Ka-pow!

I was actually referring to the metering block gasket,forgot The PV gasket too. I highly doubt the PV has ruptured, I see nothing dripping fuming after shutdown.
I adjusted idle screws to the highest vacuum, seemed to help quite a bit. I rechecked float levels, good... This engine will take and like even more than 18 deg. timing. 24 and still will not kickback on starter on hot starts. ?? Makes me wonder what`s the most initial guys have run on street machines?
Still waiting on making it legal, to do any real tuning, too many LEOs in the area to chance it.
The fume smells could be the tank vent and open element breather. where on break in It was running off a fuel can close to the pump. I guess I should wait and get it on the street, with engine under load and a few blasts then check plugs before I get too excited on diagnosis.
Still getting that initial Crack out the exhaust on cold startup although not as bad.
but still don`t like it. I`m sure it won`t cure itself.

I have no fascination with ramming initial timing at the engine. The correct initial timing Within a couple of degrees,always comes out in the wash at the time you set the T-port sync.
