hi having problems with my carb set up. I've change the carbs to:
rs 36
main jets 137.5
pilots 17.5
needle postion 4
it run find at low revs but when it hits 3,000 to 4,000 revs it run rough gets worse when warm. its clean ups after 4,000 ,and run well.
next test I'm going to change needle to postion 3 and cartune the pilot circuit.
any help would be useful
cheers

when you have the problem at 3-4k revs - is that
0-1/8th throttle
1/8-1/4
1/4-3/4
3/4 to full ?
may help track down which circuit to play with

thanks lee
think its about 1/4 throttle when holding it there it run rough. when i give it full throttle from 2,000 in top it run straight through it with no problem. thinking its the pilot circuit in fine tuning.

change the needle to position 2 and run really well a bit of splutter at 3,000 to 4,000. going to lower the main jets to 135 and see if that just smooth it out. I check the float hight as well.
cheers lee

adjust my float hight as per the manual. they were all out. went for run a lot smoother bit of a splutter at 3,000 to 4,000 rpm and ran a bit rougher at lower revs.
it started from cold with no choke so going to adjust the pilot hopefully that will sort it.
