so
i got a new spark plug, gapped it and put it in. drained the old oil, put in fresh, fresh fuel with stabilizer, new air filter, new mount adapter and remounted the blade, which i again checked for balance. now it won't start at all. Even after several pulls. soooooo....gonna have a friend help me check the new spark plug for a spark. if it has spark, which I suspect it does, not sure what to do next. i still need an answer on that autochoke vane in video 3 and make sure that is assembled correctly.
so, that leaves timing which as far as I know isn't even adjustable.
