bubbles in fuel line-boiled carb
hi to everyone!
i imagine i have the same problem with a lot you.bubbles are in my fuel line all the time from cold to hot.also the fuel inside the carb is boiling when the engine is hot.i've heard about varor lock situation.vapor lock is caused from air leak?i took my measures though.
i sealed my backplate and carbs neck with rtv silicone and i am thinking of sealing the exhaust's manifold from the side of the exhaust's port.is it a good idea?also what other part should i seal?

if you are getting air bubbles in the fuel line something is leaking, either your fuel line has a hole in it, or its leaking at the nipple on the fuel tank, or your tank has a leak

RE: bubbles in fuel line-boiled carb
ok if you have air bubbles in the fuel line, how is the engine causing that.....its either the fuel line or the fuel nipple or the tank causing the bubbles, the fuel is boiling because you are A. not tuning correctly or B. you arent getting a steady, adequate fuel flow (aka bubbles in the line)
