Is the immediate rich the accelerator pumps? Leaning out at the upper RPM needle and seat size?



thats what Im thinking. I get a dump of gas and go rich. then it runs out and I get a lean spike. Why it creeps back a little lean at the top of 2nd gear and then again in 3rd, i have no idea.

Im going to try 2 things next week end. take out my 34 squirter and try a 28 and see if that mellows the initial rich and spreads the squirt longer to prevent the lean.

I also have a brown 500cc pump cam I want to try.

For the lean creep in second, maybe its the outboards fully opening??? I have plain springs in there now. I would think the outboards would be wide open at 6000 in first and stay that way thru 2nd and 3rd. I want to try some others.

I wish I knew when the outboards were opening/fully open. I need to figure out how to rig a tps to the outboards
