Since it did not snow this weekend, I took some time do catch up on maintenance of all of my yard equipment . . . 2 snow blowers, lawn mower, and a lawn vac.
My new Troy-Bilt 2410 snow blower
: I pumped some more grease into the gear box. I changed the oil on it several weeks ago.
My old Toro 521 Snow Blower
: I did a seafoam decarb by soaking the top end a couple of times through the spark plug hole. That seemed to help the valves a bit, but the piston still looks like it has a fair amount of build up.
Then I ran the engine at a moderate throttle and did some water decarb. Still a fair amount of buildup left on the piston. The valves look better.
I'm not sure if there is any thing more worth doing . . . the engine runs OK. So, I changed the oil and replaced the spark plug.
Troy-Bilt Mower (550 Briggs engine) and Troy-Bilt Lawn Vac (625 Briggs engine)
: I changed the oil on the summer/fall equipment - lawn mower and lawn vac. Probably should have change the oil sooner, as it looked pretty bad . . .
Anyway, the Toro 521 looks like it has got more life left. . . just need to fix the reverse gear. I wonder if there is anything else I can/should do to get more decarb without pulling the head off ?
