Kohler genius needed

Hi all,I have a Kohler 8hp spec#30108A and serial# 796926 K181S. I tore this apart and rebuilt it(I don't know how or if it ran prior to my owning).I had it all back together and all it would do was fart out the carb once in awhile.Has spark,getting gas.Pulled it out,tore it down again to check timing marks,appear good to me.No balance gears.Has starter/generator(rebuilt also).In the book it says points should open when the "s" centers up in the inspection hole,it does not do this(static timing).Points begin to open at tdc.Any help would be greatly appreciated.I am guessing this is from the late 50's or early 60's.Thanks for taking the time to read this,Poppa...

It's been a few years since I worked on a Ole K series. But, All I ever done is rotate the engine until the points plunger rod was at the furthest point out then gap the points at 0.20". They always fired right off and ran just fine.

If you are sure the timing marks are aligned on the camshaft, then the things I would check are the flywheel key make sure it's not sheared (this is a posibility since the timing marks won't align).
Check and verify point gap and operation.
The next thing I would check is the valve lash to make sure you have sufficient clearance on the valves.

As far as I know there is no electronic conversion for this engine. You might want to check the crankcase breather, you should not have pressure in the crankcase when the engine is running, this may be causing oil to squirt out onto your points.
