DON; Anyone?

I may have another problem besides contaminated fuel. Yes, the truck idles rough. But, I am also wondering about the two-notch gasket I installed under the carburator.

The instructions that I downloaded from the Holley website states the two notches go toward the idle screw side of the carb. But, I read a post or stickey recently that said I need the four-notch gasket. And, the parts manual shows a carb gasket that does not have any notches. Which is correct?

I mounted the 2-notch gasket with the notches toward the idle screw (toward the valve cover side). It idles rough. I do need to adjust the timing, but the question still remains, anyone have the page that describes the correct carb gasket?

Yes, I have dirty fuel, but do I also have the wrong carb gasket?

Thanks again team,
