Hey guys. I'm new to the forum and have a couple questions. I finally got my blaster built and it's running really rich. Boggs really bad at low rpm. Took the main out and the guy before me was running a monsterous 350 main. I dropped a 300 in it and it helped significantly but still Boggs. I was hoping I could give you guys some information on my blaster and see if you can help give me a starting point for pilot and main. I have a 02 blaster. Motor was just sent out to Ken Oconnor and bored to the next piston size. Nothing major. And it has a little porting done to it. Stock carb. Uni filter. No air box lid. Bills pipe with a freshly packed fmf power core 2. Running a new BR8ES. Running 32:1. Any information would be much appreciated. Thanks guys.
 
I have heard that little R can cause some problems. Try to find a B8ES.
 
The main jet has nothing to do with anything but above 3/4 throttle.
You need a stock 32.5 pilot jet in there and tune the airscrew........

While your in there checking for the 32.5 pilot, check/set your float height.....

And set your needle clip to the middle slot.

Once you get the low and mid running right, plug chop that 300 and adjust accordingly....
