CV carb issue on No 2 carb

[Suzuki mad]

Hi all, my E's been sat since last September when I ran the fuel out by running the engine and putting it to bed for the winter. Battery on trickle charge etc etc.

Came around to Wednesday of this week to put new fuel in it, check the battery and fire her up as usual. She chimes up OK apart from No2 carb. Plugs seem all OK with spark, fuel seems to be getting through yet the exhaust is colder than the others.

I'm going to change the plugs in case its a duff plug but my nose tells me its a blocked jet, port on No2 carb. Why would No2 go wrong when being sat when its normally No 1 or No4 that block up? Maybe a bit of rust or muck in the jet?

Its an 80 GS1000E with 46,000 on the clock in standard trim, airbox, filter etc.

Thoughts.....

leaky petcock?

How's your oil level?

Good place to start! After running awhile , pull # 2 plug- wet or dry? If wet, suspect bad petcock. If dry, might be stuck float- though this seems unlikely if you ran it out of fuel- tap on carb body to revive.

I changed the pet cock 2 years ago with another NOS vacuum version. Works a treat. I'd not though of a stuck float so will give the bodies tap a try.

She runs better on choke but doesn't fire crisp on all 4 and ticks over at about 900rpm when warm. Last year when I started her up from her winters sleep she wouldn't fire on NO1 which was a duff plug hence the thought of this time. Plugs haven't been changed since 2010 but she's done less than 1000 miles in the two years.

I prefer to drain the carbs, remove & plug the gas line. Id bet that you have a plugged pilot jet. I had that a lot until I chnaged to the method above. No matter what you do the petcocks will leak fuel over time.
