When you cleaned carbs, did you remove and clean #7 Idle jet (attached link to diagram below)? Also #3 which is your main or high speed jet. If you have good compression and good spark on all 4 cylinders, you may have a fuel delivery problem.

Yes sir I did I have an oil leak coming from the inner exhaust cover about half way down on the right side I don’t think it’s contributing to my problem but needs to be addressed
