If you found this video helpful, please LIKE and SUBSCRIBE!! Today we are going to try and "reset" a Stihl MS-261C with no carburetor adjustments. It starts and runs, but is not getting enough fuel. The saw has been fully serviced and checked for all other issues and everything seems to be in working order. Unfortunately without an adjustment to give it a little more fuel on the top end, my customer will have to pay a Stihl Dealer to finish the service with their fancy dancy computer program..... Be aware! These M-Tronic devices are used on Stihl Chainsaws and brush cutters. Fortunately Echo has not put these on their outdoor power equipment.
