I have two problems that I can't find answers to.
The first is on start up, the engine smokes excessively and from idle to 2000 rpm runs rough. The second is when operating at full throttle the engine will just shut off. Starts right up again and will run fine up to 5000 rpm or so, but if I try to take it to full throttle again it will shut down. It's not a fuel suction side problem. Any one out there that has any ideas?
