My 74 VA, which I ran in Stock class at Tomahawk Cup has been sitting since May.
I had pulled the header pipe off over a month ago to get measurements from it, never re-installing it until yesterday.
Not using a proper new exhaust gasket, I noticed a ton of leaking from there and also where the chamber and header slide together, Awesome design btw??
Fix- I used a gasket material and beer can to make a temp gasket which was marginally better than nothing, and I used some HD fabric type tape at the chamber connection point. All sealed up...??
Now easier to start and idle but when gassed it's smoking like crazy and soft seizing, I check carb and notice one bolt hole is stripped, yay?
I ALSO quickly learned that my problems were worse or headed that way as I was doing all this without a jet holder+jet I failed to replace in the encarwi.
FUCK YEAH###(should consult doctor about lowering dosage)
