I used propane and carb cleaner to look for leaks and I diddn't find any. Which is good.

Here's the situation though:

Cyls 2, 3 and 5 are working fine. Unplug any of the plugs and the engine stops.

Cyls 1, 4 and 6 don't appear to be idling at all. Unplug them and nothing happens. Even all 3 at once.

If I spray a bit of carb cleaner into 1, 4, or 6, the idle speeds way up. So it sounds like the problem is fuel, not spark or timing.

So the idle circuits on those cyls don't appear to be working at all. I'll pull them apart and check them out tomorrow. Also, I'll try swapping jets from one carb to the next and see if that changes anything.
