Hi all.
I've had this snowblower for 2 years, always started on the first or second pull.
Last week used the snowblower without issue.
2 days later it wont start.
I'm getting gas because the spark plug is wet with fuel.
Thought maybe I flooded it so I cranked the engine over with the spark plug removed, then installed a new plug.
Still not starting.
I took the plug out and grounded it to see if there was any spark and there was some, but appeared kinda weak.
I took the ignition coil off and tested on the 20k ohm setting and get 9.85 ohms of resistance between the spark plug connection and
the coil body and the same reading to the ground tab.
What is the desired resistance for these coils?
I've read under 10 is good and also it should be under 5 ohms.
Which is correct?
The engine won't fire even with starting fluid so It's gotta be a no spark/weak spark condition no?

Welcome to the forum! I don't know what those readings should be. If you close the plug gap down, as a test (to make it easier for the spark to jump the gap), will it fire then?

Low compression could also make it not run. Can you do a compression test on it? Admittedly, it seems somewhat unlikely for compression to suddenly get messed up from sitting around.

I did not try closing the plug gap down. Figured if it wouldn't fire using starting fluid its not going to fire period.
Just ran outside and checked compression, after 4 or 5 cranks I got 150 psi....
I should also note that I checked the wires for bare spots or something grounded out.
All wiring appears fine,even tested both switches with an ohm meter to verify I had nothing grounding out.
At this point I'm thinking its gotta be the coil??

My thought was that an iffy coil might not provide enough spark to jump the normal plug gap, under compression. So no matter what fuel source you provide, no spark = no running. But if you closed the gap down, and got at least *some* kind of spark, it might at least run a little. If the only thing you changed was spark related, and then you got some activity, you could better say it's the coil.
