Hey Vic, you have two jets that you need to clean out on each carb. One near the top, one near the bottom. You can gently poke a paper clip in there to clear out any gunk. Sounds to me like that will get you going.

If not, then first place to look next is the fuel lines/fuel pump.

Cleaned the jets with a small wire and got alot of stuff out of them but the problem still.persists.The primer ball does not get preasure where the ball gets stiff does this maybe trigger the problem or could it be a float problem getting stuck.thanks for the reply
