I know, Rick, I know....

When that is said; Rotating assembly is rated to 1500 Hp/ 8000 rpm. And it's lasted for a couple of years now, without any issues. Oil pressure stays the same, noe need to adjust valves, etc.

Worried about the Comp solid rollers: yes. Will run one more year and then inspect.

Back to the webers: As 12.5 in AF ratio is a bit high for a N/A, I have to try 140 main jets just to check. This might eliminate the off- on throtttle issue and also bring the gas fumes away when criusing at 3000 at the highway.

And there is unburnt fuel leaving the engin; after every run when engine is turned off, it takes 30 seconds before a dull but loud BOUM sound leave the exhaust.... Should have uploaded a sound file- really funny thing.
