11hp little wonder wont start

I took my little wonder out this spring and it started up but with limited power. Had to run it with the choke 1/2 on. I figured it was the carb from sitting all winter, but took it apart multiple times and found nothing in there.
Now the engine wont start and I have 0 compression reading from my compression tester, also my air filter is covered with oil.
I'm guessing from what I read on the internet that it might be a bad head gasket?
I'm just looking for a little direction/ advise.
Thanks in advance for any help.

Head gasket sounds like a good bet.

I finally got around to working on the blower and removed the head yesterday. The gasket appears to be in good shape, looks fairly new. The cylinder is not scorn at all either

I brought the unit on craigslist late last year from a white collar suburban homeowner.(not a landscaper) and it looked to be in well maintained condition. It had a tag on the handle and I was told that it had just been serviced (I figured just a tune up). It ran great to clean my leaves up in the fall but than quit on me this spring.

When I took it apart I noticed that all the gaskets seamed to be fairly new. So I'm thinking that it was either not tightened down properly or the bolts vibrated loose. I removed the bolts with a socket on my cordless drill so I'm not sure how tight they were.

When I reinstall them what is the torque setting that I should use, and would you recommend putting anything on the bolts so they don't come loose?

Also is there anything else that I should be looking for before I put it back together. I ordered a new gasket kit and have a few days before that comes in


Thanks for any advise.

Is the piston moving? Even a badly blown head gasket usually allows some buildup of compression. With 0 on the compression gauge, I'd suspect the engine is blown or a valve is hung wide open.

Yes the piston moves up & down as well as the valves are opening and closing like I think they should

I should have done a leak down test ahead of time but did not have a tester and could not find some place to rent one.

That should have made some compression, I think your gauge might be defective. It sounds like you have a carb problem and might possibly have a problem with rings, overspeeding, or gas in the oil.

The gauge worked because I tried it on my chainsaw to confirm. Is there anything I should look for before I put it back together?

Also what are the torque settings for the head when I reinstall it.

Thanks
