Plugs are totally fouled after maybe 100 miles. Extreme carbon buildup in muffler after the same 100 miles on a new muffler. Smells awful. Moving the wiper on the AFM to make it leaner increases idle ...

Hey y'all, I have the square port heads (029-101-371B) on my late 78. Are the valve adjusting screws 10mm or 8mm? Only reason I'm asking is because I need to order them today and I don't have access t ...

If you want one that is cheap and functional (if not OG) get yourself some 7/8 vacuum hose from any hose supply store, a 7/8 OD elbow, and 4 hose clamps and call it a day. I did that and it works gr ...
