Lots of Questions!!!
 
1. Ok, Ive posted my compression numbers before(30-30-50 rear)(60-60-60 front) and I was wondering how the thing is running! Is it possible or am I doing the comp. test wrong? The car idles(kinda high), pulls in high rpms. Hesitates like crazy in low rpms(1000-4000, I think there is something wrong with the primaries or something).

2. I am about to buy all of the following; Greddy 720 secondaries, Rtek 1.7, and a 255 walbro. I sent the primaries out to get cleaned and rebuilt. Any problems with that setup or will I need more.

3. I know that both of the top plugs are fouled for a fact. Because both the top plugs are fouled, could that be the hesitation problem?

4. I have pre mix in my tank right now and it will probably be sitting for 2 weeks. Will I have to drain it and is it safe for new fuel pump and injectors? Please help.

Thanks guys, except for Alan. Jesus Christ. Dont jack threads! Is this why I failed emissions horribly, since I didnt know they were fouled during the test?
