GS850 missing with choke

[gssuzukixxx]

I am having a problem with my '79 GS850. It starts up with the choke pulled out but cylinder #2 does not fire...that exhaust header is cold. If I warm it up like that, on 3 cylinders, and push the choke in the #2 header will get warm and the bike runs good on all 4.

I have confirmed that the choke plungers for all 4 carbs move up and down with the choke linkage.

It has new plugs. I put fuel stablizer in the gas last fall plus I put some fresh gas in yesterday.

I rode this bike alot last summer started and ran great when I parked it last November.

Any thoughts?

Thanks

Fuel side of the enrichment circuit is clogged, so when the choke is pulled it adds air but no fuel. Take the float bowl off and clean the little passage in it. It is usually the first thing to clog up from sitting a while, as it is the lowest fuel passage in the carb, and it is small. You may have to take the whole carburetor off to dip it if it's not the passage in the bowl which is clogged.

Thanks for the response. I will give that a try.

OK I have the carbs off and the float bowl off #2 carb. Is the passage to the enrichment circuit the skinny brass tube with the tiny hole?

You're the man Tkent. Stuck a thin wire up that whole, then blew some air in there. Put the whole thing back together and now I can burn my hand on whatever pipe I grab.

Thanks for your help. I love this forum.
