Got an old Snapper 21404P that's probably mid 1980's era. Still cuts and runs perfect. Ok nothing new there. You Snapper guys know the drill.
Issue is the mower has a nasty vibe to it. Has a new OEM Oregon 99-121 Super Mulching blade and the Extreme Ultra carb clean. Fresh oil, both air filters are new and plug cleaned. Deck is clean and again blade is new. Thinking previous owners must have hit something in the yard? Unless the blade is somehow a dud? Crankshaft is the next thing. I put anti-seize on the blade bolt and torqued to 40 ft lbs.
Engine is the stellar Briggs MAX Series (prior to Quantum) 4hp 190cc Super Engine. The oil stays crystal clear/clean. Amazing from a 35 plus year old engine. Doesn't use any oil either.
The vibe is there from idle to max revs. Thinking bent crank? What do you guys think? Could swap in another new Oregon blade to rule that out. What is the best way to check for a bent crankshaft?
