Motor cranks and runs fine except for one big problem. When engine in cranked idles at 1500-3000rpm most of the time. However, there are times that idles perfectly. Choke seems to be functioning ok. Does not seem to be a problem with throtle linkage. Can change from high idle to correct idle...

When moving throttle forward slowly and reach about 2,200 rpm enginge speed increases rapidly. Don't know how high it would go but pull back when it reaches 4,000-4,500 rpm. When throttle is pulled back goes back to idle fine.
Any thoughts on what could cause this run up...
