blaster wont start

I bought a blaster that wouldn't start. I replaced the stator and now I'm getting a spark. But still there was no action in the engine. So I cleaned out the carburator, and filter. Still nothing is happening. I put a bit of gasoline under the spark plug, and tried to kick start again. Still I'm not getting any explosion in the engine.

If I put the new stator in wrong and my timing is incorrect, would this be causing the problem? If so, how do I get the timing right?

Or any ideas what to look at next?

Which are you missing?
Nice hot blue spark?
What’s your compression?
Because of wires stator can only go on one way. Did you install key in flywheel?

I got a blue spark. I assume that means it is hot enough. I didn't measure compression. It feels like I have compression when I kick the starter, but I will check that. I didn't forget the key, but I also assume the flywheel wouldn't be spinning and I wouldn't have the spark if I forgot the key.

Check all of the above. Also check reeds to see if broken or not sealing on tips .
Just remove carb and shine a flashlight in carb boot. Tips should seal tight to metal cage.
Is carb good and clean? Pluged jetting from sitting. Especially pilot jet.
Fresh gas and oil?

Thanks very much. That's what I'll do next.

So we spent several hours on it yesterday. Used a proper spark tester--spark is good. Used a compression tester--it holds 60. Checked reeds--turned them over--they are sealing. Fuel is coming through carburator. Got one very small explosion when I sprayed starter, otherwise nothing.

One thing that is strange: there is A LOT of resistance in the kick start. I have to use all my weight. Even when the head is taken off the engine, it is very hard. Could that be causing the problem? Could it be that something is stiff or seized up in the lower engine and I'm just not able to get a big enough explosion to move that cylinder?

Thanks for the advice. I did exactly this. I found out that when the cover is off the engine, everything spins nicely. When I screw the cover back on, it is extremely hard. I then saw where the cover is being scraped--also where it had been cracked and re-brazed. So that's the one problem. But unfortunately there's another:

With the cover off, I took the clutch right off and put a cordless on the drive shaft--spun about 1000-1500 rpms. It still doesn't start and run on its own. I know there's spark--I checked with a tester. I know there's compression--I tested it at about 60. I know fuel is getting through--I was spraying carb cleaner directly through the barrel of the carburator, and I could see wetness on the bottom of the spark plug. The magneto is one of the ones with slots. I tried it rotated one way, then in the middle, then the other way.

Help! Is there something stupid that I'm doing? What should I try next?

OK. Someone told me that 60 was fine. But I guess he didn't know what he was talking about. Where's the first place to check for leaks? Or do I have to assume I need a new top end? (Former owner assured me that top end was good.)
