 Re: Is there a proper way to adjust the float in the (toilet) carb bowl?
There is a school of thought that those slots on the intake manifold at the junction can leak. I have no idea since mine never did. Someone said his were cut too long somehow allowing an air leak there. I'm not quite sure how that worked. If you grind them down, the carb tube would seat deeper I suppose. I honestly don't know.
A backfire is a violent change in pressure so again I have no idea. It shouldn't be backfiring to begin with though. But a backfire might blow out your sealant since it has to go somewhere.
There is no internal pressure in the gas tank to my knowledge. It is my understanding that the tank is purely gravity feed so has to be vented to prevent a vacuum from forming when the gasoline is displaced. Which is really what a vapor lock is I think. |
