Re: Gas Hog

Dang that is alot of fuel. There is just no way that could have happened, that much fuel would have flooded that motor, and poured out the carbs. I would check for a fuel leak somewhere. Seriously, you either have a leak somewhere, or maybe your fuel gauge is messed up.

Re: Gas Hog

Well obviously the motor isnt running right. The first thing to check is the fuel pump. If the diaphram has a pin hole in it it will dump fuel thru #4 cylinder. Look at that plug and see if it doesnt look different than the other three.<br /><br />Good luck!

Re: Gas Hog

If its a "new to you" engine, I would put in a new fuel filter and put in a fuel pump rebuild kit. Then check all hoses and fittings for a leak. "Normal" fuel use should be about 6-8 gal per hour at WOT. Probably 1-2 gal per hour at toon drifting speed.
