What filter did you pull to see valves?

Here is what you do to check valve lash.

Remove the valve cover, just under the int and ex. ports. Turn the piston so it is TDC on the compression stroke. Generally speaking, no more than 0.010 gap and no less than 0.003 on either valve.

You wont find the valve stems inside the case, they are under the breather where you checked th valve lash. Only things in the case are:

Governor gear
Crank
Rod
Piston/rings
Cam
Tappets.

On your L-Head engine the valve lash is adjusted closer by cutting the valve seats, and opened up by grinding the end of the valve stem.

OPn Sprigs OHV engine, he has a large valve cover on top of the engine, he measures valve lash on top of the engine by doing the TDC thing, but he measures between the Valve stem and Rocker arm.

If your valve lash were out, you would have either no compression, or an extreme difficulty pulling the rope.

I pulled the air breather filter to visualize the valve stems ( Intake valve ) I pulled the exhaust to see the exhaust valve stem, there was alot of carbon build up as well on the exhaust stem, i cleaned it as best as i could without tearing into it further, the valve stem on the intake is pitted and so is the exhaust valve stem but not as bad. They appear to seat well but i know even a tiny gap will cause a problem, in the end i just may replace the valves after i get through replacing the coil, points and condenser. Here are some more pics.

Sorry Red I misunderstood that you were meaning the points gap. Thanks for pointing out the holes in the bowl assembly I'll pull the plug today and check it out. I'm pretty sure its getting fuel as far as the bowl as before I replaced its seal that was where it was puking out (someone before me didn't seat it properly and crushed an edge, doh) Has to be something simple................just has to be. I'll letcha know how it goes and thanks again for the advice

Definately

Valve job time...no question. Call around and find someone with a Neway set and have them do the valves. If you buy new valves you will still need to set the clearence and cut the seats anyway. If you measure the clearence correctly you will find that you have next to no clearence and I can see that the intake has been leaking by the coating in the intake pic

That is a snow engine and the damage that it shows is from overheating. That engine is designed to operate with the shrouds over the carb only below around 45 degrees F. The bore does not look that bad but the shrouds that wrap around the carb, muffler, and cooling fins needs to removed and replaced with an air cleaner for summer use. You will most likely also need to replace the crankcase breather (The valve stem cover) as they distort when overheated
