How much fuel is through your JS? If it is still around the gallon mark you need to give it a little more time to warm up before you hit the track.
MY JS is nothing like any OS I have ever owned and I doubt any of them are. I have about 1.5 gallons on the engine and it will stay that way as it will never be bolted in any of my cars again.

Are you running an odonnel plug, JP series pipe, or some crappy fuel? (these 3 things make the motor run crappy) If you are having a hard time with a p4 plug try a p5, stay away from jp series pipes, and keep the low side needle a little leaner then you are used to. Only thing else I can think of is you may have over temp'd or rev'd the motor and made the rod a little sloppy. You just can't come in here short fused with a
fit like a 5 year old who didn't get his way and yell this motor is crap without trying to figure out what your doing wrong first.
First off this is a public forum and I CAN say what I want. If you think I am crying like a 5 year old then so be it. My engine is junk. Yours may be great and I am happy for you as I don't doubt there are a few good ones out there but mine was and still is junk.
As for fuel...you are right it may be the problem. It is most likely equal to the quality of the engine. I think it says EB Mods on the side of the bottle.
I am also running a P4 plug and a Ofna 086 pipe which were all suggested by Ed Bridges himself.
