Default Only Backfires Through The Carb Regardless Of What I Do (1450)

I got my engine back from the machine shop. Turns out my binding issue was two-fold. The crank needed to be polished .0005", and the aftermarket rod was doing some goofy binding.

Now that I have every single thing back together I can't get it to run. The official Kohler manual says the points should be set to .020". I read in the archive that .015" - .020" might work. Someone even said as much as .030". I found in the library where it said to go off of the S on the flywheel. I tried every technique and I still can get it to do more than backfire through the carb! Every once in a while it will run for a few seconds, but it's fighting the piston, and runs rough! Everyone's probably thinking that the timing is a tooth off. I checked that before I put everything back together. The "." on the cam lines up with the "-" on the crank.

I'm really at ends wit here. I tried setting the points from .012" - .030 in .oo2" increments, and it still wouldn't start! Everyone was right. I would have been a lot of time and money ahead if I would have bought something new with a warranty...

I'm really stumped on this one, and I'd appreciate some input...

If I can't figure it out can someone suggest where to get something like a K341? I'd also like to know if there is a conversion kit available for this for pointless ignition. I know for sure it will at least need a new flywheel...

Thanks!

Mike

EDIT:

I forgot to mention the carb is a brand new Walbro unit....
