Wisconsin AKN Starting Problem

Hello all, I also have a AKN Wisconsin that I got about two years ago now. I went completely through it and lapped the valves and glaze braked the cylinder. I also rebuilt the carburetor as well and cleaned the magneto and the points and gaped them. Now the engine has incredible compression, an old fart like me is dead tired after six pulls trying to start this thing. Watching You Tube videos I see people getting there Wisconsin's started easily. So as this is my first Wisconsin, what am I missing? what are the carburetor adjustments? Any Magneto tricks? type of spark plug? If I use starter fluid it will start on the first pull but usually die. Then comes the "fun" of trying to restart.

Turn the engine slowly the direction it runs and when the mag clicks, see where the keyway on the crank is. It should be just past up (TDC). If the mag doesn't click, the impluse on the mag isn't working.

Ok got a chance to play with the AKN and I can not see the key way but there is a casting on the flywheel that says D|C (Dead center?) anyway, just past that point is where there is the loud snap of the magneto.

You can't see the key way on the output shaft? If it fires just past TDC, it wont kick back when you are trying to start it.

Ooops my bad I was looking at the fly wheel side, I'll check it tomorrow, but I still know I was on top of the compression stroke.

Which carburetor do you have? Is fuel actually getting to the carburetor? You can crack open the line at the carb to check.

Hold the spark plug wire about 1/8" away from one of the fins on the head and see if it sparks when the mag snaps. You may have to put the plug wire on a spark plug and hold the main part of the plug against one of the fins to see if you have fire.

My AKND (same as AKN but heavy duty) has a Marvel-Schebler carburetor on it and according to the manual the high speed needle valve should be set between 3/4 and 1-1/4 turns out. If you have it too rich or lean it may not be starting well.
After I have mine running I put the generator under full load and adjust until it runs smooth, but about a turn out is a good starting point after a carb rebuild.

Is your choke working properly? Mine has a loose choke shaft so the choke spring detent thing sometimes causes the choke to open the moment I pull the start cord. It basically won't start for me without the choke when it's cold, it's kinda awkward, but I'm able to hold the choke closed while I pull the cord.

I use the generator all the time, it's a fantastic machine and I never have issues with it. My general starting procedure is open the fuel valve, close the choke, turn the engine over by hand 4 or 5 times to prime it, then give it a rip. Almost always starts up on the first try, always on the second. Except the one time it was sitting all night at -25F, it took 3 or 4 pulls...

Also try to avoid using starting fluid, you probably won't hurt a low compression flathead with the stuff, but it's really bad for any engine.
