Starting up old rototiller

[Oaktree]

I'm no expert on Tecumseh engines, sorry.

If it gets fuel and the carb is new, that leaves spark and compression, right? How are the spark and compression?

When did it last get a new spark plug? If it were me I might start by checking the spark and the magneto alignment, and if that doesn't help, I'd check the valves.

Pretty sure I replaced the plug and am getting spark (been a couple years since I fiddled with it). Didn't delve into it any further at the time. Wasn't a priority project, really ought to get back to it.
