Yup,I picked up another SEZ yesterday for free from a high school classmate.Joe told me that he always mixed the fuel to the correct ratio of 32:1 & he went to pull the recoil & it was locked up.He assumed the engine was seized,but I'm not convinced at this point that it is.I pulled the recoil to make sure it wasn't locked up,it wasn't,it works fine.Next I pulled the drive case cover to see if the clutch was locked up,it wasn't,but the outer bar plate was on upside down & one of the corners was bent.I thought that might've been what was preventing the engine from turning over half-heartedly,but that wasn't it either.The last thing I did was to pull the muffler,that'd tell the tale.It looked like new,no scoring at all.I've been told to pull the flywheel & check to see if a bolt had backed out against the flywheel thereby locking it up.That's on my list for today.I did examine the fuel line to see if there were any cracks that'd cause it to suck air & lean out,but the line was like new too.If the saw had leaned out the piston would've been toast.I put some penetrant in the plug hole & in the exhaust port,but my money is on a bolt that'd backed out & locked up the flywheel.BTW,the saw is in beautiful condition,has a new chain,& you can still see part of te Homelite logo on the roller nose bar.It has a plastic AF cover & recoil,so it's a newer SEZ.I didn't look to see if it had tags,but I'm sure it does.Pics to follow if I get to the cause of it being locked up & rectified.

Post up some pictures when you can!
I had the screw back out on mine once and lock against the flywheel. I thought for sure the unit was seized, I'd pull the flywheel and check it out. If nothing else, it doesn't take long and cost anything.
Good luck, the SEZ was my first homelite (first gas powered saw actually) and holds a special place in my heart.

Agree with Rowdy, fuel tank screw behind the flywheel is the go to deal on a locked up SEZ. I wish I had a dollar for every one of them I've pulled the flywheel off of and loctited the fuel tank screws.
Fingers crossed that your ignition module works! Good luck!

I went to take the nut off for the flywheel & the flywheel turned! I think you guys are right about the screw backing out qagainst the flywheel.I was then able to take a look at the cylinder & it's pristine!Not a scratch in it anywhere.I tried like heck to get the flywheel off,but I couldn't find the screws for the puller.I had my hands on them just recently too.Once I get the flywheel off & put that screw back in & give the carb a rebuild I'll have myself a good little SEZ!

After wasting between 4 & 5 hrs.on this little PITA I 've deciderd that I've got other saws that are more deserving of my time.All of that time was spent on trying to get the flywheel off! I've heated it,beat it.pulled it.I've repeated this process several time to no avail.When I snapped the head off one of the bolts in the pawl spot,that's when I called it quits.The only way that flywheel is coming off is in pieces.

Spray some arokroil on it and let it soak. One of mine was like that, thought I'd never get it and presto. "It's the only oil that kreeps".

I had another saw with the same problem.I sprayed it with PB Blaster & let it sit for a few days,then I picked it up & put on my work area & gave the flywheel a couple of sharp blows with a drift pin & hammer & it popped loose.The SEZ has been sitting for about a week now with Blaster sprayed in the key slot,so maybe I'll check it today & I'll get lucky again.

I finally got the flywheel off today.Unfortunately there were no screws or bolts that backed out.When I turned over the engine by using the clutch it'd lock up at one certain point & it'd click internally.I came to the conclusion that a crank bearing had gone bad on it.I don't feel so bad now that I broke off one of the fins on the flywheel.Lol Just another saw for parts.

It's been quite a while since posting about this saw as it sat all this time.It's winter & it's the time of yr.when I part out a saw.I was really only interested in getting the rear throttle handle off to use on another saw,but that cylinder was just staring at me so I had to take it off to see what the problem with the engine was (curiosity got the best of me,Lol).After I got the cylinder off the piston turned on the crank just fine,so I knew it wasn't the bearing as I'd originally thought.Then after further inspection I found a gouge that goes all the way up the piston & into the rings too.Apparently it ate something that didn't agree with it.I don't know what it was,it must've fallen out when I removed the cylinder.I did find the head of a worn screw in the fuel tank though.
