I opened my carb and saw gas in this piece its part of the rear carb. Is this suppose to be a vacuum? Or should gas be in here? The front one was dry and never seen gas in there.
That's the coast enricher. I don't think there should be gas on that side of the diaphragm. It works off vacuum, the diaphragm opens a port on the inside and allows a small amount of fuel into the mixture on deceleration. Could be it's leaking through the diaphragm. Could be the source of the air leak too.
