Carb tuning with oil pump delete.

[Dmitri]

Switching to running premix this year. Car has ran very well with the jetting currently in the carb, anyone have experience with switching over and were jetting changes required?

I changed over this year, didn't really notice a difference. A little smoke with premix, like it should, but didn't notice anything else.

Don't run it with Lamdas tho. They will mess it up and not give a good reading. So I was told.
