No visible oil leaks. Runs as expected but I’ll check the crankcase vent. Plugs look good. I change the oil and filer once a year since I only run it maybe 10x a season.
So I bought this mower new in 2015 and it has less than 200 hours on it. I’ve been very consistent with regular maintenance. Last fall I noticed a little smoke on startup and it goes through a lot of oil. Is there any other adjustments for valves or something that I’m missing?
