Ariens ST824 sprays gas out muffler

    I have an old Ariens ST824 with an HM80 Tecumseh engine. It would not start up this year. I have replaced the entire carburetor with a brand new one, changed the plug, drained the gas and replaced with new gas. When I try to start it with the electric start I get gas spraying out of the muffler. Does anyone have any idea what I should take a look at next to get this thing running? Thanks in advance for any help.

    Does it have spark? What's the compression?

    Just checked, it has ZERO spark. Good compression.

    Do you mean to turn the key off or replace it? Replace the coil too?

    No. Meaning it's either in the ignition circuit, or coil, or airing gap, or flywheel

    Take off the covers to get down to the coil. Remove small wire that goes to the Key or Switch. Put it back together with this wire off. See if it has spark. If yes it should run. You can choke it to stop it from running. Now you need to find the short in the wire or switch.

    If it still has no spark - is the flywheel rusty on the magnets? If so clean off the rust and rest the air gap.

    how old is it? it may have points - in which case it could be a cleaing/adjustment, or maybe a replacement.

    oh, and condensor should be replaced too if points are replaced.... should be under $20 for both if you need them.

    Just wanted to update this thread and thank everyone for the advice. I got it running. My older engine had the ignition coil and everything else behind the fly wheel. After I got the fly wheel off I figured I would just replace everything. Coil, condenser, points and since I was in there the fuel line. Sparked right up and started right up. As for cost, the new carburetor I installed first was $97. Turns out that probably wasn't contributing to the non-starting, but I've had problems with it for years so I kept it. New ignition coil was $32, points were $12 and condenser was $5. About $150 all together to get it up and running again. Better than $1000 for a new one.
