I was using my ms 180 yesterday ( saw is 5 years old) and the rpms were racing on either its left or right side and up side down. Now I am pretty sure the seals are going and this is the problem but the saw was only $200.00 when I bought it. I figured to just get another small limbing saw . May get a rear handle 201 and have brad hook it up or is there a saw that is close to the weight of the 180 that anyone has used and liked ?
