Questions about Arreche 19mm carb install

[wedenj]

OK, I got my stage 2 kit from provoscooter yesterday for my '04
Triton and started the install. The 70cc kit was a pretty straight
forward install.

The carburetor is another story all together…. There were no
instructions with the carb and the ones on provoscooter are lacking
some of the fine details a novice needs to do this install it on a
Triton. The first issue I ran into was what hoses go where? The small
hose was a no brainer (I think) but I'm not positive I have the
others in the right place. There are two connections on the engine
side of the carb, one has a barbed fitting and the other just has a
knob at the end. Then there is a barbed connection on the side of the
carb, I am guessing that the hose coming from my gas tank with the
spring type guard on it goes to this connector.

Still on the carb… how do you get the spring compressed and the
throttle cable connected to the plunger? There has got to be a trick
to this that I am not seeing. Do you disconnect the throttle cable at
the handlebar to give it more cable at the carb?

On the new carb there is a silver 90 degree bend with threads on one
side and a rubber boot on the other. I screwed the threaded side into
the plastic plunger top plate now…. do I leave the stock adjusting
nut on the throttle cable and that gets shoved into the rubber boot
adapter or does the stock adjusting nut have to come off?

That's it for now, but I am sure I will have more questions.

Thanks,

Jay

Well, I had all the hoses hooked up right and Rob from the yahoo vento group confirmed it for me.

For anyone who is doing the upgrade here are some carb tips:

*All visual references are looking down on the carb with the engine side facing you.

The hose connections:
Two are about the same size and one is a lot smaller.
The smaller one, which is the oil line, gets attached to the small barbed connector on the right side of the carb (this one should be obvious). The hose comming from the gas tank with the black spring/coil around it goes to the barbed connector on the left side which feeds into the bottom of the carb. The last hose goes on the last connector, the one without any barbs on it just a nodule towards the end. That’s it... I had to use zip ties to connect the hoses to the carb as the stock hose clamps were too weak and the hoses fit too loosly.

Throttle cable 90 degree bend cable thingy:
If it came installed on your new carb, remove the silver 90 degree bend thing that is screwed into the top of your carb. It looks like this

only with a rubber boot on the end with the nut. Grab your stock carb twist off the 90 throttle sleve being careful not to damage the threads. I had to apply heat to the aluminium to get it to release. Once you have it removed, you will notice that no threads are present and it's a little too big to fit in the plastic top of the Arreche carb. You will now need to get a lighter or torch and heat that metal neck up to the point where it will melt plastic. Heat it up and gently insert it in the arreche top making sure you have the neck aimed towards the front of the scooter but don't cover the screw holes. It is a good idea to "dry" fit the 90 the throttle cable and line everything up before you melt it into the plastic to get an idea of what the best angle will be. Now let everything completely cool down before messing with it. Now that you have all that together, the stock adjustment thing for the cable should screw into the new carb top just like the old one.

With the above completed it should be pretty easy to connect the throttle cable to the plunger and spring. Just remember to put the gasket on the black plate before assembling the rest of it because it will not go on after.

When starting 'er up for the first time you may need to remove the air filter and cover the intake with your hand to choke it.

I have not had time to do a plug read, so I have no experience yet with adjusting the carb. Thanks again to Rob for giving me such great help.

Hope this helps,

Jay
