Number 4 not firing

[Guest]

Well that's got it. Bolted everything back up and she fired right up, including #4. A lot less smoke out the right exhaust too, I'm hoping some miles on the engine will clear that up completely. So the culprit was my fuel mixture screw was set wayyy out allowing too much fuel in not allowing the fire...as Octain said "something simple". Would this problem effect my vacuum synch on the carbs? when I synched them earlier I can only assume #4 wasn't firing and now that it is should I resynch?

Glad you got it sorted.

If you set the synch right in the first place, with #4 not working, it'll be fine now - it was still pulling vacuum exactly the same even though it wasn't firing (ok, for the purists it will have been the tiniest fraction different).

Good to know, and thanks to everyone for their advice. Took her on the road today as it was dry, man does she pull. Big difference between my 850 and this one. Can't wait to take her out for a few hours and see what she'll do.
