Continue to have idling problems, runs great on initial start and then goes into a mode after (a minute) where it loses power , (it does not appear to be slow mode, I have experenced that before). I have replaced the theromstat, checked the compression, change the plugs all are good, ran it from a separate fuel tank, same issue. I premix my gas and thought I had a fuel pump issue since it would only run WOT when I continuosly pump the bulb. Removed the VRO pump and replace with a non VRO fuel pump thinking the engine was starving for fuel. Same problem exists. Thinking this is a carb problem. Not sure where to go now other than the dealer. Thoughts?
