WOT Sputter
 
I have put new heads, intake, distributor, and installed a new 600 cfm Quick Slayer Carb on my motor. I am beating my head against the wall, for some reason I have a sputter when you nail the throttle. I have adjusted the float and the air fuel mix screws and it still sputters. Is there something I am missing here.:hc:

All I know off the top of my head is the total timing. I will have to get my buddy to come over and we will check the initial.

I wasted a lot of time Saturday chasing a sputter, I timed it, changed the coil, fuel pump and then changed out the dizzy internals. All that work and it turned out to be the combo of a paper filter and a little water in the gas. It was all parts I had laying around so it wasn't expensive, just don't forget to start with the simple stuff.....

That's what I hoped we have installed all new fuel system tank to carb. I have been doing some research today, and I think I may check the accelerator pump adjustment. We have been chasing this sputter for 6 months I have never been great at adjusting carbs.
