Ok I have done some troubleshooting so hopefully someone can help me figure this out. The motor starts and idles normally. After warm up if you punch it she revs right up. it then bogs down and will only run sooth at 1/3 throttle. If you got to idle for second you can punch it again. It's like it sucks all of the fuel out of the bowl and can't keep up. Fuel pump maybe???
Try it again but this time manually pump the primer bulb while running. This will basically temporarily take the place of the fuel pump. If you can run like a scalded dog, you probably have a fuel pump issue.
Also, do you have a fuel tank that has vent setting? If so, make sure it's vented.
CMOS
Well the new tank and line did not change anything. Same exact rev up and bog down. I did run around for a while with my finger on the choke and it ran full power as good as it ever has. It would make sense there is an air leak at the flange or the bowl that causing it to not suck enough gas at WOT. I would thinks it's the flange and not the bowl because I can pump the bowl full and don't see any gas leaking.? This would explain the sudden change after I initially worked on it.
Question? Am I safe to use some black permeated gasket goop on both gaskets to help seal them up.
