I was checking the vacuum pistons for cracks and noticed that each one has another small hole on each one at the bottom by the jet needle hole. Does the second hole go closer to the butterfly or closer to the intake side?

I was looking at the manual and it says nothing about what side the hole goes too.

thanks for any help.

the slides can only be installed into the carb in one direction. try it... they are not symmetrical.

once again you are the bomb kkim. I got my new jets in yesterday and had the carbs apart to make sure everything is clean and clear. I will update my previous post about hanging idle when i complete the cleaning and adjustment.

Slide lift hole goes downstream of the needle in each carb.
