Pulled out the Troy Bilt 5550 today, washed it off because it was all nasty from mice crawling on it for the last 10 years. Wiped everything down. Sucked the old gas out of the tank, which didn’t smell that bad. Put some fresh gas in and it fired right up on the first pull. Then it blew mouse nest crap out all over. Decided to pull off all the shrouds and make sure nothing was blocking the cooling fins. Got all that out and blew it all out with compressed air. Had to pull the carb off to get the front cover off. Didn’t have an internal torx bit small enough for the carb bolts (Briggs engine), but my smallest 6 point metric socket got them out. Then had to fix the kill switch wire because mice chewed the insulation off a 2 inch section near the coil. Put it all back together and ran it for 15 minutes with a load on it. Ran great and didn’t hardly faze it when I ran the miter box along with the vacuum. Then changed the oil. Put some Toro synthetic 10w-30 in it because that’s all I had.
Ready for work tomorrow.
