150cc AC.
What is the best jet size (sizes) considering I live at 3300 feet elevation and never get below 2500 feet?
I have a Deni but no idea what's in it right now other than I think it's just not getting enough petro-chemical.

Just to help you a bit maybe what you are basically asking is similar to this...
What's the best size pants? I have no idea what size I have on but they are too tight...
Unfortunately the answer is too vague. A bigger one than what you have.
First why do you think you are lean? Have you moved the needle up? Adjusted the fuel/air mix screw? Start with those jetting is the last resort... When you have done the above and you are still lean then find out what you have and go one size at a time till your too lean symptoms subside...

Thanks for that reminder - I had not moved the needle up.
Done now but my carb does not have an adjustable needle, so all I could do is slip a tiny washer and raise it a small amount. No further raise is possible. I got it up maybe 1/64 inch. not much. And adjusted the mixture. I have a couple other things going on right now so I can't test it until next week. Have to get rid of engine knock before I destroy the engine so if this doesn't work...well I'll have to see.
