Default K301 Carb Adjustment

Hi folks,
It's been a wile, but im hoping I can get some advice and here is the scenario:

Last fall I put a little MMO in the gas tank per the instructions, and near immediately it started having running problems which I attributed to the MMO doing it's job and loosening sediment and shellacking in the gas tank, carb or anywhere else. It would run at the lowest idle but wouldn't take any gas/throttle, so I figured the high speed jet got clogged. I put the machine up as I'd broken my ankle a couple months before and didn't want to be walking back and forth for tools.

Now this year, I removed the carb, disassembled it noting the position of the Jets which was 3 turns on the main and 2 1/4 on the low idle. When I removed the carb there was no gasket between the carb and block and came that way from the previous owner, but a gasket has been put back during assembly. When I put the carb back together, I looked up default starting point for the carb and set them at 2 for the main and 2.5 turns out for the low. I figured perhaps the extra air that may have been leaking in from the back side of the carburetor was compensated for by allowing more fuel with the extra turn.

I can't get it to run using either the default settings or the old settings. It does fire, but that is about it. And it will fire on every key turn. I notice the carb throat wet so it seems to be getting gas, but I can't for the life of me get it to run well enough to even do the final adjustment needed for the jets.

Any thoughts would be greatly appreciated. I'm getting tired of recharging the battery in between attempts.....

Thanks in advance.
