Hey guys first time on this forum. Looks like a lot of good knowledge!

My 300 fourtrax ran like a top when I parked it some fiveish years ago. And I’m sure it had some ethanol in it.now I know better.

The bike would run with the choke on it but rough. And the exhaust pipe was cherry red so I figure it was really lean.

I emptied and flushed out the tank and took the carb apart and soaked it in cleaner for about an hour. I cleaned the jets the best I could. They were really gummed up and in bad shape.

When I put it back together it’s running better but it’s still not right. It will run a few seconds without the choke but not long.

Do I need to set the idle speed before I mess with the air mixture? And how Cani do that with it on choke?

Should I take it back apart and try again with a new kit or do y’all think I can adjust it out?

Thanks for the help guys. This thing has got me kinda stumped.
