Snowblower hard to start

[I Lean]

Cliffs: what's an acceptable compression number for 2 stroke yard equipment?

I have a Toro CCR 2500 snowblower that has been awesome for the last 15 years or so, but has been difficult to start this last winter. Once it starts it runs great, just lots of pulling on the starter cord first. Spark plug looked good (replaced just now for next year's use), carb seems fine (cleaned out well for next year). Since the easy/obvious things seem fine, I did a compression test....just under 90. Is that low? It seems low-ish to me, but I don't know what it is supposed to be either.

It's a Tecumseh engine, if that makes any difference.

You ought to be able to check resistance in your coil pack as well as plug wire. My guess is they aren’t giving you the voltage they once did.

Check the primer bulb and hoses to the carb, sometimes they crack and you can't prime it which makes them hard to start. I've fixed lots of these if you need help.

I'll check those things. Thanks for the input!

More than likely you need to adjust the valves.

The CCR 2500 is a two stroke, no valves

Ooof sorry. I'm so poor I can't even afford to pay attention. 🤣

90 PSI isn't a lot for a 2 stroke Carl.

Pour a few drips of oil in the spark plug hole and pull the cord a few times and recheck the compression numbers- if they bump up 10-20psi,
I'd say you'd need a new piston/ rings.
