Thanks Spud! I have another question for you or possibly Weldangrind. I ordered a new Mukuni carb today (The one that is recommended on here so much) I am going to free up the exhaust by gutting the cat, and I have a uni foam filter to go in the slightly modified stock air box
(I opened up the intake holes about double the original size) I operate primarily at 5000 - 8000 ft above sea level, where would you recommend I start with the jetting, with these conditions in mind?_
P.S. this is a 229cc engine

I defer to Weldangrind, who is the resident, Mikuni carburetor expert.

I'll accept enthusiast, but I'm no expert.

Can engines even run at that elevation?

I'd start with a 115 main and a 30 slow. If it won't start despite adjusting the pilot mixture screw, go to a 27.5 slow.

Thanks for the starting point. I'll put in an order for some jets to get started with. BTW I see that there are 2 different styles of slow (pilot jets) for the vm series carb which ones does the carb in your link take?
