I put in new rings a Hi compression head and expansion chamber. Now it only runs with almost full choke, if I take it off it dies. I'm running out of ideas..

Run it out or drain into a container and add a little gas to get to 32/1. Or mix a new batch. Too much oil actually makes your fuel/air mix leaner but all the oil washing through fouls up the running so you can't tell it.OK, I had a new (NT) carb lying around and threw that on, (no O-ring). That cured the full-on chock condition and it's now operating fine. Now I'm getting the 4 cycling condition and then it kicks in the does the 2-stroke, so it's on and off. I'm running 20:1 cos i'm breaking in my new rings. Do you think that's what making it do the 4-stroke?
Just guessing but after the gas is right drop the needle. It's all trial and error, but it is logical. Fun really. Take your time and change one thing at a time.Thanks' Slogger!! It bogs off of idle and then in the midrange all of a sudden it comes on and runs great (2-stroking) then at the WOT it seems to bog again. I will thin out my fuel as it has a fair amount of smoke coming out of my chamber.
Yep. I figured as you break in it will need that 'extra gas' that is making it burble. More power, more gas. An engine can be looked at like an air pump.Thanks' Slogger & Tyler, yes I believe I'm getting a little ahead of myself and need to let the rings seat because it is running better little by little. Lol, yes this is fun as you fix things you learn.
I don't know. you wanted high compression, sooo..Wow, I just did a compression test on this little air pump and it is producing 165 psi. Isn't that a little too much? I do have a high compression head. My plug is looking dark brown to blackish.
