Thanks for the suggestions. I have a couple of things that I am going to try. I found that the main needle was not centered in the brass adjuster so I stole the needle valve/spraybar off of an old ST 40. The spraybar has a round profile instead of the two flats so we'll see if that and the concentric needle will help. I'm also going to tweak the timing to see what effect that has. I did find a bit of crap around the original needle so I added an inline filter right before the carb. Hopefully some or all of these changes will help and if it would stop raining I could find out [sm=drowning.gif]
