I finally got the boost problem sort of fixed. Seem to have been some film or a particle in th eboost valve limiting me to about 13 psi. I may need a new ball but for now I've got it limited to 15 till I get to drive it some. Seems that 15 " vacuum is about normal for the A-237 camshaft. I'll start playing with the adjustable cam sprocket this week. Seem a lot of guys have found 4* advance a good setting. I've detected some hints of surging, probably the same thing Dan ran into. Soon as I run the tank empty I'll drop a 190 Walbro in it and get an adjustable FPR in the system. I can really feel a need for a bypass valve now so I'm going to have to figure out how to plumb that in.
