The engine starts well. the engine will run up to full RPM and then it will break down to one cylinder. Plugs look good and I suspect a coil breaking down. May need to order one so if someone can check your sources for a year I would appreciate it very much. I also will test the needle seat.

Thanks for U R help! JOHN
