Gentlemen today I had a customer come in and pick my brain as to what is the matter with his saw. He has a Ms 460 that he purchased recently. The saw was checked out and he was told it was fine. ( servicing dealer stated this ) Well he has issues starting it so he removed the limiter caps, reset the H and L to factory settings 1 turn out and the saw would fire on the 3rd pull , then fast idle but in run it would just die. He tells me he adjusted the LA and it made no difference. He put the saw on his bench and went in to have dinner. Well he comes out and absent minded adjusts the saw again 1 more turn to H and L ( now 2 full turns out ) and the saw fires up on the 3rd pull, then fast idle and then it runs as it should. Acceleration is crisp BUT the LA screw has little affect for the idle. ( runs at about 2800-3k 2500 is spec IIRC ) well he lets the saw sit over night and it fires on the 3rd pull.. fast idle then runs .. be it a little quick idle wise and the chain creeps a bit. He looks at me and asked sooo what ya think? I said well.. I am thinking carb kit, maybe a leaky seal or a bad carb ( had an 026 that acted exactly the same way and it was the carb that was the issue ) What say you fine gents?
