View Full Version : Carb/throttle trouble

didnt get a reply to the last posts in the other thread...
so... today i take the scooter out and it wont start.
i get the carb adjusted and get it started.
cant get it over 12 mph.
well, the theory was that the cable was too long, about a half inch too long.
so i try pulling on the throttle cable like someone sugested and i swear it went to 40mph in a block NICE!
did it a second time to see, and when i let go of the cable, the scooter kept going.
i took off the air filter and looked inside and the carb was stuck half throttle.
i got it somewhat fixed, and it got stuck again, just past where it would be if the idle screw was all the way in.
i took the cable off the carb, and played with it, and etc.
put it all back together without the cable and it was normal, moved up and down inside the carb freely.
put the cable back on and it still wont idle where its suposed to.
all i can think is that the cable is stuck somewhere.
but it doesnt seem to be.
it just acts like the cable is too short now.
my girlfriend was going to take it into the shop tomarow morning.
but with it idling way to high theres no way id let her take the risk.
so i figured id drive it, just have her follow in the car.
but now the damn thing doesnt even start. :confused:
any ideas?
im tempted to scrap the whole thing. but then id be out quite a bit of money, and transportation.

screwed all the way in.
i took apart the hand side of the throttle, to see if maybe it was stuck.
it wasnt, but now i cant put it back together.
lost one of the two screws and broke the elbow.
wtf. now im going to spend the next couple days trying to get the shop to come pick it up so they can replace the cable, elbow, screw.
im so pissed im almost in tears, my girlfriend was allready crying.
i just dont understand how so much can go so wrong on such a simple thing.

you broke the elbow, and lost a screw? Sounds like you may have been a bit rough with it?

just a bit last night while i was trying to find out what was wrong with the carb.
when i took the handle apart and gave the cable more slack to see if the thing would idle where it was suposed to, it was still stuck in the carb.
i think i may have recieved a bad carb.
it makes sense to me, it hasnt run right since it was all put together, no matter how it was adjusted.
the mechanic at the shop said that is why he didnt leave the variator, clutch springs, and torque spring installed.
and the throttle cable actualy does seem to be about the right length but its hard to tell now.
have you taken out the slide to see if the needle is bent?
get back to me about it ok. I will help you threw it.I am doing the stage 2 kit also on my 2004 zip R3i Turbocam. :D
I am doing the same thing installing the stage 2 kit and having some trouble with the cable.
I was wanting to know if you are checking the cable were it splits to two cables. one to the carb.One to the oil pump?
Maybe that is were your problem is?
get back with me soon. I can help!
How is it conected to your carb.
Did you remove the big threded nut?

lol.
i didnt even know there WAS a split to two cables.
i bet that is where its stuck, if it is indeed stuck somewhere.
Malformed

yes indeed.
it was pulled out of that splitter box.
fixed it up and it now returns to proper idle position! yay.
but, theres too much slack on the cable i need to shorten it a good half inch or more so that when i turn the throttle it actualy gives it some gas. ;)
and it still wont start... it tried, put put put and died right away.
i assume my carb needs some adjustment.
my legs are sore from trying to kickstart it... i will let the shop handle it since my mechanic still has some work to do on it... like shortening the cable like i requested in the first place!
good job
i took the slack adjuster off my cable and ground it down a little and cut the threds off the other carb elbow and used that as a slack adjuster :D

i saw that i could do that with mine when i installed the carb.
but if your going to do something, do it right. ;)
i refuse to rig my scooter when i can just as easly go get some cable ends and use a crimper.
only reason i havnt done that yet, is because with it being stuck like it was i didnt know how much to cut off.
i need to go to a bike shop to get some slime filled tubes for my mountain bike anyway, i will pick up a pack of those crimp on ends.
you know there is an adjuster on the cable that hooks up to the oil pump.
i bet a couple turns would be enough to make sure the motor is recieving the oil it needs. (i dont like premixing gas+oil)
this adjuster is working just like the stock one i don't jimmyrig things
what i did was make a adjuster nothing that was wrong or sloppy so don't
say it's wrong what i did :mad:

well... the cable was too long, so the right way to go about it would be to shorten the cable, not make the elbow or aduster longer.
my mechanic tried to shove the stock elbow onto the new carb, it looks and functions just fine but tell me that it isnt jimmy rigged.
shortcuts arent cool when you are talking about high speeds in traffic.
unless you are talking about screwing things together nice and tight, which didnt work for me because the stock elbow adjuster and the new elbow dont match up, infact, none of the combinations of stock and new carb cable elbow parts matched up. it was a loose fit at best. if its loose it will cause excess wear on the cable.
the way you did it may look and function perfectly fine, but i did try pretty much the same thing and it was sloppy and jimmy rigged, so i dont know how you did it.
what im saying is that its just as easy to cut some length off the cable and crimp on a new end.
try not to get so defensive, do whatever works best for you.
the way i did it it screws togeather tight like stock.
the mechanic that did yours jimmyriged it
the parts i put togeather don't move and won't pull apart

then its all good! ;)
wish mine fit together nicely, so i dont have to mess with it anymore.
i may have to rig it up just to get it to the shop.
took me a good half hour of kick starting to get it started and running.
but even then it wont move unless i push it. lol
but atleast its running again, thats a start in the right direction. :D
even though i made a adjuster i am going to need a new cable.
you might olso because the spliter won't lit the carb slide open all the way.
i am working on that myself that might be your problem also.
yes it's good :D

i noticed that too.
seems odd that no one else reported this problem.
if you decided to run without the oil being premixed it would just be a matter of using one cable.
i might have to buy new cables and a splitter, because i realy dont want to premix the oil+gas.
im going to shorten the cable a half inch and see if that works...
if not, im probably going to just run one cable for now.

splitters for example.

i just got back from trying to fix the problem.
i removed the cable and found it off the track in the spliter again.
I got it back togeather and it works great you can check and see if this is your problem.
1) remove the speedo head cover (6 screws under sideof it)
2)remove throttel cable from lever
3) look threw opening under headlight and find 2 smaller cables on the left side
4) pull the 2 cables making sure the cable at top dose not snag anything while you are pulling it
5) you will see the spliter open it. the cables should be on the track.
6) reverce the steps to put back togeather. you might want to get a wire to help you fish the wire back up :D

mine should be fine inside the splitter but i will check again.
maybe mine is just a matter of getting a half inch of the cable cut off capped and crimped. i will try to do that tomarow.
for me, it was just a matter of taking out 4 screws (i think) and the 3 silver bolts inside the front compartment/trunk.
im thinking a better splitter may be a good idea anyway, they arent all that expensive considering how much work they actualy do.
expecialy if you decide to replace the cables.
out of curiosity...
how fast does your scoot go now? full throttle.
50+?
im anxious to see the difference when i get done.
i have not even started it yet
I will start it tomorrow then i have to break it in then i'll let you know
i can't wait to ride it :eek:
good ida to get a better spliter if you want to run the oil pump
the stock one is cheeply made

well i had mine up to 40 in a block.
40 isnt impressive, but the accelleration was awesome.
that was also with the stock variator, rollers, clutch springs and torque spring.
im sure i could have gone faster but i was coming up on a curve and i was getting scared. :eek:
when i get my cable all fixed up and adjust the cable so the oil pump puts out a bit more oil...
we will see. :D

scooter is running sweet. not much accelleration, but it went up to 40+ pretty easly. i got the cable shortened a half inch like i had planned... it was almost too much. (i cant adjust the idle down very much)
thats no problem because i can allways strip off an 8th inch or so from the cable housing.
i didnt take it on a main road because i didnt have the seat on it yet and its dark out. still need to get the variator and clutch springs put in, along with the torque spring.
that should help the accelleration a bunch.

this problem getting it started is pissing me off.
i get out of work today and i get it started EASY. and it dies.
then i cant get it started.
give it some gas, no go. dies on me.
block the air filter, and start it, give it gas, and its fine.
it seems to want to start different every time...
any way to get it to start right away every time like it used to before putting the carb and etc on?
remove the automatic shutoff valve, and add a manual shut off valve maybe? and just put a cap on the vac fitting on the carb?

that manual fuel off valve is probably an easy place to start...
The other... Check your auto choke... make sure the little "U" clip is in place holding it in the carb tightly... or it will wiggle around while driving and cause the scooter to start differently every time... I did that to mine when I first upgraded.... Looked at the "U" clip and tossed it to the side... then realized I needed it a few days later after fighting to get it running right...
Let us know if one of those might be it...
Malformed

naa that clip is on good.
i will re-crimp the wires for the choke tomarow and make sure the choke thing is in all the way.
if that doesnt help, i will add a manual fuel shut off.

not having the choke plugged in probably won't cause that problem, depending on your temperatures....
Lennox ran his for months without hooking the wires up on the choke... but he's in florida... so it's warm there all the time...
I battled mine even with a manual choke in sub 40 degree temps....
