Re: Why no help?
Since we can't see your engine, give us something to work with. Power loss -- but how so? What RPM does power fall off. Did it ever run right. Did you just acquire the engine? Does it start? Does it idle? Does it have spark on all cylinders, did you do a compression test, does it have fresh fuel, did you try activating the choke/primer or giving the primer bulb a squeeze or two when power falls off. Is the primer bulb being sucked flat which indicates a fuel line restriction? When were the carbs rebuilt last, and what have you paid others to do that didn't work? See how this works???
