What kind of mileage is on it?
Is it a misfire or drop off in performance? Does it rev cleanly above 8k or not.
Does it backfire (misfire) through the exhaust or die and pick up again?
Misfire is usually, (not always) electrical and drop in performance is usually (not always) fuel/air related.
Have you changed the air and fuel filters?
Did you do a compression check?
Is it worse when hot or cold?
When they cleaned the carburettors did they check the tiny inline filter in the fuel line T piece on the centre of the carbs?
