Saturday Ill be picking up a lawn mower Ive been wanting for a long time, a Snapper self propelled with the Robin Wisconsin 2 stroke engine. Ive heard these are just as bulletproof as the Toros with the 2 stroke Suzuki engine. Its a 1986 year model, runs great, and the guy said parts are still available. My question is, should I use it regularly or keep it as more of a vintage piece? 40:1 or 50:1 fuel mixture? Those who have one or experience with one please chime in. Thanks
