Secondly, I get the bone head of the year award. I pulled off the air filter assembly and there was no venturi in it! I pulled it all off and cleaned everything and I guess forgot to put the 6.5 venturi back in it. That is the dumbest thing I have ever done. My problem was 2-fold. Front bearing starting to leak and a dumb #$% human error. It was tuned for 6.5 and didn't have it in there so no wonder it was lean. It was not lean bogging though and running great until it flamed once you let off the gas. Anyway, I need to get a bearing and replace it before this weekend. I think I should be good. I feel confident after looking at it everything is okay just a really dumb user error I will never make again!!!

New rule also. All my engines get new bearings no question asked every 2 gallons from here on out, maybe overkill but that is what I am doing.....
Make sure your rear bearing is nice and tight with no excessive play as well.

You can go 3 gallons on bearings, if not 4 or 5.
