Talonhawk,
What jetting are you using on your carb? I am trying a 34mm pj keihin carb on my friends Trailblazer with the HPD trail pipe,porting and slip on filter. I need to be close. It came with a 152 main and it wont run. I cant tell if it is to rich or lean. Are mikuni jets and keihin jets different and do they go with the same size increments. Is a 150 mikuni jet the same as a 150 keihin jet? Anyone have any info? Thanks!

If it bogs bad I would say it would be lean before being rich. They should try and run but "blubber" if they are rich. I would start with the needle clip in the next to last (4th) position and go to a 160 main jet. Ohhhh. I forgot too, I run a 48 pilot jet. Dont worry about what pilot it came with for now as long as it tries to idle. Adjust the air screw for the best possible idle then work on the needle and main jet to start with. Just remember that jetting figures are the same, bigger number is richer and smaller numbers are leaner.

I was told by keihin that the stock 152 jet is like running a mikuni 230 jet. Way to rich for his application. We then dropped down to a 120 main and it runs real good. Still a little rich but we are in the ballpark. Now We need a smaller pilot jet. Stock is a #58 and am going to try a #35.
