Well i picked up a F7 carb that dosn;t run, i know its a fuel problem but i can't figure out what it is. I cleaned the crap out of the carbs hoping that was the problem, i put back the sled toghter and it does the exact same thing. The sled dosn;t idle and runs better on half chock then full chock. Im new to this power valve stuff, could dirty power valves make it run better on half chock then no chock?

My next thing is to put a new fuel filter, then i guess rebuild the fuel pump. Anything else you guys could think of i should be looking at? The sled has 1200miles and its a 05 snopro 700

If you bought it used make sure it has the right pilot jets and they are clean. Look for air leaks like if it had reeds then took them back out when sold. Power valves need to be the same and within spec or it will fault and not run to good but should still idle. Are you adjusting fuel screws keeping air scew low
