Adjusting a Polini Carb

Postby strangelimey » Sat Dec 10, 2016 2:19 pm

I recently bought a Polini Carb upgrade for my Genuine Stella 4t

Unfortunately, I can't see any way to adjust the pilot screw while the carb is mounted to the engine. It's underneath and the cylinder is in the way.
Anyone found a solution for this?

Thanks

Hi there!

I use one of these Motion Pro tools for getting to hard-to-reach carburetor adjustment screws:

I'd be surprised if one couldn't find the same thing cheaper on eBay or something.

Another option is one of those flexible screwdrivers that they sell at auto parts stores, etc...

If your pilot adjustment screw is not recessed down into the carburetor body (though I think it is...) you can attach a tight-fitting vinyl hose to the end of the screw, and install the carburetor, then twist the hose to adjust it one way or the other.

Maybe one of those options helps?

Another trick that I have used before, is to use a 1/4" screwdriver bit, and turn it with a 1/4" wrench. You can get into some tight spaces with that method, but it is a real pain to use it for adjusting a carburetor.
