TOPIC:

Am I missing something? I have spark, good compression, when the bike is running I can unscrew the drain plug on that carb and gas comes out. 1,2,4 pipes get hot but #3 I can touch just semi warm Anybody? I just put on new wires and plugs too.

Just because you have gas in the carb doesn't mean it's getting into the engine cylinder.
You may have to take your carbs off and clean out the passageways.
Can you smell gas in the cylinder when you remove the spark plug?

I smelled a slight hint of gas Then ran out of time Going to check that again today and pull carbs off again I have cleaned them out 2 times already

Some possibilities --
Assure proper adjustment of #3 pilot mixture screw (might be too rich).
Check service fuel level in #3 float bowl (clear plastic tube method). Might be too high. Does it match levels in other carbs?
Pay particular attention to cleaning pilot circuit: pilot jet; air passage; air jet (if applicable); fuel passage.
Assure enrichener (choke) is completely closing on #3 carb.

Good Luck!

Patton list some good possibilities.
If you've had the carbs off twice already and you're sure all the passageways are clean, then check some of his suggestions.

I had a problem like yours before, and I ended up going through the carb again and used compress air to blow a chunk of gunk out of my pilot circuit that I probably never would have found other wise.

When using carb cleaner spray from aerosol can, please remember to use protective goggles. This toxic stuff backfires a lot.

You should wear safety glasses at all times ;)

Yeah, I definitely learned that one the hard way!

Thanks Patton and to all else that chimed in I focused in on the pilot jet and passage and that seemed to do the trick it is firing on all 4 now. I just took it for a ride and it rode great. (now just have to fix oil leak from checking valve adjustment) but thats an easy one
