Good afternoon ladies and gentlemen. A friend referred me here and told me if anyone could help it would be you guys so I appreciate any assistance you can give me.

My mom recently gave me this Huskee mower with a B&S 446777 engine and said it had been parked for about 7 years and she had only used it 2 or 3. When she parked it she said the starter was going out on it. I've since taken it apart, replaced the solenoid, starter, spark plugs, air filter, fuel filter, oil filter, cleaned up the fuel tank, and did an oil change. Once the new starter was on, I tried to crank it and the flywheel turned about 5 or 6 times without a problem but it wouldn't start. So I gave it a second and since that first crank when I turn the key, starter will engage the flywheel but the flywheel will only turn about half an inch before it stops. Not wanting to burn up the starter, I have tried limited re-engagements. I spoke with a buddy who said it sounded like a valve problem. So, with advice from him along with some how-tos online, I adjusted the valves to manufacturer specifications and it has not made a difference. I can turn the flywheel by hand and it's not terribly difficult but it does require some muscle. I'm wondering if anyone has any suggestions on what may be wrong and what to try next. Thanks for any assistance you can provide.

Are you sure the engine is not flooding? This might be caused by a float issue in the carb. That would explain why it locked up after cranking a bit.

Excellent post by motorhead....Remove both spark plugs, see if eng cranks , and cranks fast...Beware of fuel spray ..If still not cranking, you may have a foreign part that wiggled it's way under the flywheel, and now jammed.....

Wow! Thanks guys for the quick replies. I pulled the plugs and the flywheel is considerably easier to move by hand. I cranked it and it turned the flywheel about one or two full revolutions and then it stopped. After that initial one, it is right back to just turning a half inch or so before it stops.

I would've guessed hydro locked like Motor and susofign. I'm also guessing that you've left the plugs out while you try to turn? Or did you put them back in? Hopefully the engine is not seized.... I'm sure that's worse case scenario. That thought crossed my mind since it's been sitting for such a long time. Hopefully the experts will be around here soon. They'll get you lined out with some good ideas. Good luck!

Since the engine still doesn't turn right with the plugs out, I'd suspect that something is jammed under the flywheel, like suspicion suggests. Otherwise, the starter may not be working right. Can you turn the engine by hand continuously, or does it lock up after a few full revolutions?

Motorhead, I just turned the flywheel six full revolutions and it never stopped. There is one specific point in each revolution that it seems to get quite a bit more difficult to turn but I can still push past it.

With the plugs in. With the plugs out it becomes considerably easier to turn by hand and still never stops at any point.

I tried starting it again without the plugs in and the flywheel rotated about three times before stopping. On subsequent attempts it returned to only turning a half inch or so. I was able to hand turn the flywheel multiple rotations without any problem.

So, the plot thickens. I started thinking about how I was getting cranks but directly after nothing at all. So, I rethought the whole process and decided I was going to get a different battery and lo and behold this thing began cranking immediately and fast and free. So, I'll be buying a new battery but it seems now that I'm not getting fuel to it. My clear air filter has a small amount of gas in the bottom but I do not think it is enough to think fuel is flowing. Any thoughts on what to check? I have brand new plugs in it but should I stick to thinking this is a fuel line/component problem?
