Ok, so I got the new belt on. I got the Napa belt, thanks Tahoe! Started mowing and it just died. I replaced the fuel line, it had 3/16" I'd line, thought that was too small so I went with 1/4", replaced the fuel filter. It runs decent and finished mowing the yard but the fuel filter barely has any fuel in it at all. I believe this GT has a vaccum diaphragm that sucks the fuel up to the carb? It just doesn't look like enough fuel is getting to it, don't wanna run it lean, I've blown car engines up doing that before. My ? Is how much fuel should I see in the filter? Is this normal? It seems to run ok, but ran better yesterday when I bought it.

I love these Red belts they seem to hold up Really good.No one sells these around here so I usually end up on Ebay.

Drive Belt.2692R



PTO Belt 6941R



I stock most of these on my website for a better price :poke:  :D

These are the best belts in the industry and are USA made




Napa belts are all mostly for auto applications and are not power rated no matter what the guys behind the counter tell you.

Diaphragm might be on it's way out.They get stiff and distorted over time.


Diaphragm kit here.$23.00



Or the whole kit.$68.99 + shipping



I've tested these before down at the farm using a Vacuum pump with pressure gauge.My uncle has one that he uses to test his old chain saw carbs.He has a pretty big collection of old McCullough saws and is always getting more to tinker with. 


I think they're $20 at harbor freight.



I pump it up to 2-5lbs and see if it leaks down.If it leaks down then it will more than likely need the full kit with the Valve plate.If it does hold pressure then all it needs is the diaphragm.



One of our Site sponcers may have these kits a bit cheaper.

Take the pump apart, soak the rubber diaphragm in motor oil for about 10-15 mins, then clean off and put back together. The oil will soften and swell the rubber some, may get you going again,

That's a great idea Tahoe. I might try that tomorrow after I get off. It's officially dead now, only will run at idle .
