Very nice! I just went to harbor freight yesterday. My dad literally checked me for money before we left because he knew I wouldnt be able to walk out of there without a new project engine. So I came back with nothing but I have to say they seem to be much higher quality than the 9hp clone I have. I say get the 50$ cam from AGK along with an ARC rod and your good to go. With everything you have done it should really have woken it up!

Sounds good to me! Did you do anything to the timing yet? That could help just a bit. I saw your post over at bob's and I just thought of that for whatever reason.

[1992suburban]

stock timing...

the e-tube on mik's (and others) some have more holes or less holes. some holes are bigger, etc. but on the miks, they are different sizes for different slide needles.

Every jet recommendation across these forums suggest a #90 main jet (assuming for a 6.5hp engine). This seems strange given many different setups and engine versions. Stock jet is #72, #90 seems like it will be too rich for most people.
Do the exhaust and air filter upgrades really demand that much more fuel?
Did anybody do the spark plug reading tests?
