VIDEO UPDATE. Here's where I am currently with this mower. find a manual or take it to a pro
Cleaned the crab pretty good, first thing I did when I got it. I keep thinking it might be the linkage. Fuel tank is brand new so it can't be that. Maybe I will double check the carb.Revs sound waaay too high for one. Going to stretch the rod out LOL. Put a tach on the ignition wire. Keep her under 3600 revs fully warmed up, no load.
Carb linkage not adjusted proper? Dirty carb and fuel tank?
Make sure it is mounted right. It should say this side up or something like that.https://www.amazon.com/dp/B0038U3LZU?psc=1&ref=ppx_yo2_dt_b_product_details Here is the coil I installed.
I've been checking for spark by simply grounding the spark plug tip against the engine. I was thinking about getting a test light.
