After a 20 year hiatus from the hobby, I recently took an old K&B .61 out of a long long storage. I bought the engine new, ran it long enough to break it in, put it away, and only recently dug it out again.

The engine turns over freely and has good compression. However the front bearing is really really sloppy. Fuel will leak out of it.

I hooked up a new freshly charged Hot Shot 2 and a tank of new Omega 10% fuel. I tested the Hot Shot and it works fine.

The glow plug is a new Fox idle bar plug, screwed in good and tight.

I set up the high and low speed needle valves as close as I could to factory settings, and blew through the fuel inlet to make sure that it is not too clogged.

I tightened up the carb nut to keep air leaks down.

Only after a massive amount of priming, maybe 10 or 20 revolutions, will the engine kick over, complete one or two revolutions, and die. I maybe got it to run three seconds on one occasion.

The results are the same whether the tank pressure line is hooked up or not.

I played with the high and low speed needle valves but not much seemed to change.

The engine is definitely getting fuel; I can feel fuel leaking from the front bearing.

Where am I going wrong here? If the engine wants to start, I must be fairly close. I have a sneaking suspicion that I am almost there, something not quite adjusted right....
