plugged exhaust?

Well, removed fuel inlet and it was clear. Removed both main jets and blew out passages and blew out all vacuum ports. Seemed to clear it up just fine. I bet my secondary was plugged. Runs great now, was able to weld my exhaust back up ( thanks for THAT advice!) And we should be good to go. New rad cap and coolant too. Wish i could isolate that 1 little valve tick, other than that im happy.
