Honda CB1000c

I've got a small problem. I just picked up a 83' CB1000c, and it has not been ran since 87'. I checked the crank bearings and thy are in spec. with no rust or embedding. The rings and cylinder walls are in good shape, and changed the plugs and plug wires, but when I went to fire it up it ran a little off. missing on #3 cyl. intermittently. So I checked carbs re-cleaned and tried again. still missing. checked plugs thy are good. Still missing. Does any body have any clue what may be going on?

How are you judging that it is missing? Due to a cold exhaust pipe? are you getting fire to the plug consistently?

Ive got fire to the plug, and yes the pipe is running at 210 not at 285 like the other three at the head. I ran a few tanks of 95 octain gas with some carb cleaner in it, helped some. Carbs are spotless, running id. 35, mid. 68, and main 110. For a stock bike that should be good, but still spitting gas out the exhaust?????? I've been working on bikes for years, but this one has me dumbfounded.

Hmm sounds weird. I think putting the carb cleaner is a good move though. I guess you've done that enough that you can't get it to clean up though. If you have good compression and have good spark about all left could be that one carb. Maybe a float is sticking? Is the plug fouled when you pull it out? If it completely dry maybe it's somehow still a spark issue? I'm sure this is the same kind of stuff you've been thinking of though. You're really just gonna have to systematically eliminate everything that could cause it.
