Thanks carburetor Al for responding. I don't need to rejet yet but I ride all year round and know I'll have to rejet at some point due to the temperature drops. I also installed an MZ65 pipe and another fella said I may have to rejet because of the higher flow exhaust. I'm pretty new to these higher performance parts and have much to learn. The Jets in the carb have no markings whatsoever. I tried a jet from a keihin clone and the diameter was to big. I'll mike one to see exactly what size I have and do more research and see if I can find a match. I have another build and installed a 18mm Mikuni because the availability and quality of the Mikuni brand.
There are only a few basic small carbs,keihn,mikuni,Dellorto and the chain saw ones.Try going on the net and entering the different carb names.If you click on image ,pictures of the carbs and jets will come up.Your jet and carb have to come up.A no name carb is only a copy of a well known carb. China copy's,not develops these parts, to keep costs low.So be patient and keep trying.I do not know much about the chain saw world, so you will have to do your search.
