wonder if you have some issues with flat level adjusment, or maybe sticky valves

Mine has the reed valves.I think the reed vlaves were on the fuel injected model
I hate to say it but I would bet that carb needs to be cleaned better. From my experience coughing or sneezing thru the carb is a sign of a lean condition. You say it happens from 1250-3000rpms, that would indicate the low speed circuit on that carb is starving for fuel. It stops after 3k, if it was a bad valve it wouldn't get better. Your high speed jet is allowing the proper amount of gas in the cyl so it smooths out.Thats my 2cent stimulus opinion.,,
The timing belts being THAT loosecan definitely give you a backfire through the carbs. It causes your valves to open at the wrong time. I'm willing to bet that replacing them will solve your issue.Do you think this is enough to cause the problems I have been seeing with the backfiringt up through the carbs?
