Stuttering!

Probably spark plugs. Got on it a bit today and it started cutting out about 4k rpm. I'm still running the spark plugs that were in it before the rebuild and before the blower. They're IT20's gapped for running NA, so I'm changing to TR6IX gapped to .028 and see how that works out. They're out of stock so I gotta wait until tomorrow morning.

Oh, and that brief period of boost put it up to 16 psi. I'm hoping for 18 or so when I can get on it for longer.

So go and change them already!:D

Brian, I had to gap my plugs at .025 with the KB 2.2 (17psi) to stop spark blow out.

You will probably need a boost a spark. I had planned on running one when my setup is done.
