This only happens when the engine is cold and its warming up...
I pull the choke to start it up in the morning. I let it warm up for a few minutes to 5 minutes. With the choke pulled all the way out, the RPMs seem to go up and down. But when its warm and the choke is pushed all the way back in, the idle is fine. No problems there. It just goes up and down in RPMs when the choke is pulled. Why would it do that? And also what is the RPMs suppose to be at when the choke is all the way out?
Thanks

I have the very same issue. After going thru the carbs and sealing the tank she runs great except when cold at idle. She seems to surge from about 1100 up to about 3000. Once warm it stops... I am trying to find out what I missed.
I am not sure where your idle should be set at but mine is set between 1100 and 1200.
