Default Re: Mikuni carb kit from Performance 670

What size carb are you getting? I bought the VM30 from them and it is tuning adventure to say the least. I put it on a stock Predator 13hp. As it is, it comes setup way too rich. I am at 180' above sea level. I am still ironing out the adjustment.

Comes with:
Main jet 260- I am at 210
Pilot jet 35- I am at 17.5
Needle jet Q2- I am at Q0
Jet needle 6DH4- I am at 6DH3

I have not gotten to throttle valve or air jet. The throttle valve only effects a narrow range. If you can get it lean enough with smaller pilot jet the air jet is OK.

If I had it to do over I would have gone with smaller carb, 30mm is a whole lot of carb.
