I had a similar problem with a clone engine I tried the electric fuel pump but it kept over powering the float so finally invested in an inline pressure reducer. When dialed down to about 1/2 pound it ran good. But I think the vacuum could have been used and been simpler and cheaper.....

P.S. Please turn off the cap locks...... it is too hard to read.

I can't help but I would check that oil is not full of gas.

I hope you get it figured out... someone here should be able to get you going!!!

Flintrock · 12-13-2009, 09:53 AM

Can you "T" the line before the carb and return one side to the tank, so that the carb will only take what it needs? I'm a little confused about "not having enough pressure to push up at an angle"? That pump should have the power to do that.......

DOOmsman · 12-13-2009, 10:37 AM

Back to first post(gas coming out around bolt that hold bowl on) I would pull that clones carb and look every thing over. New these days ain't allways done right.
