Mine ran like that....Until I installed a manual choke. I could never get that water choke to work for me.
Autozone has them for under $10. Not sure what the real problem was but It has been 4 years now with no problems......so for me that was the problem

I by passed the water choke with a peace of heater hose.
Mine ran fine until it warmed up. It seem to run real rich after words and would miss at idle. I had no power at times. A quick fix was a peace of wire to close off the choke some to get me back home.
edit: BTW mine is a trail rig so no inspection.
