Engine roughness at low idle
I've read through many posts and responses and I believe that the low-rpm engine roughness that we are experiencing is due to a gearbox issue (which I believe is near or over the inspection time anyways). The carbs are synced, the plugs are good, and the mounts are in good shape and torqued. In looking at the manual I see no reference to a "belleville" washer which is mentioned many times in the forums. I assume the washer between the dog gears which the book seems to call 2 different things is the "compression disc/plastic thrust washer" but please correct me if I am wrong. I appreciate any help or information and thanks for all the posts you all make, it has been very helpful.
