Sometime ago I read somewhere about putting a ms461 carburetor and oil pump on a ms361. For the life of me I can't find anything on this subject. Oil pump is a direct fit. The carburetor however has a few things that need to be worked out. Impulse being #1 and the linkages from the trigger and choke to carb being #2. Anybody have any insight on this? If you have done this what did you think about it?
