Watch those seals now .If after a period of run time it gets to leaning out that's usually the problem .Fact I have a 281 in the shed that needs seals and I'll be darned if I remember where I put them .Not a big deal as they are about 10 bucks a pop not like those 20 dollar Stihl seals .
Now on some Huskeys that seal has to slip over a square cut shoulder and where a lot of people make an error in instaling them and soon after the new seals fail .
It's a simple trick of using a small plastic tube to kind of "shoe spoon " the seal over the shoulder .When I get the time and motivation I'll do a few pics of how to do it .--mean while I either have to find them or buy new ones .Forgetfull minds cause tired feet .
