Thread: carb leak question

Tweet

I noticed the top of the carb is sealed with plastic (thus the oh crap correction). The plastic is covering the float vents, when the temperature rises the fuel in the bowls expands and vent vapors that can no longer escape to atmosphere are forced into vacuum and other passages not intended for fuel. As the temperatures cool the fuel vapors condense to liquid again, deteriorating parts and plugging small vacuum and air passages. Most likely this carb will require complete disassembly, boil out and rebuild.
I believe Roger caught this first.
