Think it may have a dirty injector or air leak at the injector, had no time to pull and check.
Would fire and run on # 2 cylinder, # 1 just huffed smoke, # 1 would fire with #2 for a few rev then only # 2 would run with the starter helping it along, checked the fuel line and injector pump for leaks, loosened and tightened the injector.
Pulled the air cleaner and kept cranking while # 2 popping until # 1 took off.
When # 1 fired she blew a lot of black smoke clearing after a few min.
Was going to spray/dribble water around the injector for bubble test and may lead to pulling and checking the injector for dirty nozzle.
Runs good and power is the same, worked it hard today pushing 12 inches of snow, mostly in high range.
Would like to check the valve lash but can not find the manual for the 1200 specs.
Any idears, comments would be a help, kick this around for a few.
