Idles for a while, dies if choke off or throttle opened
I just bought a 2005 1100 classic that had been sitting for 7 years. It only shows 2100 miles, and looks new. Now if I could only get it to run I'd be happy boy. Here's what I've done so far. New battery, oil, plugs.
Drained and cleaned tank filled with new gas, changed oil, cleaned carbs twice by disassembling and all passages are clean, diaphrams look new. It starts right up on full choke, but dies after 5-10 seconds. It won't take any throttle without dying. I made sure it has gas in the bowls, even tried bypassing the fuel pump, no change. Pumps out a nice stream when disconnected. Stock air box connections tight, no change when squirted with carb cleaner or wd-40
I got it to rev up a few times with starter fluid or carb cleaner from the air filter tube, but couldn't duplicate even that now. Dies if choke is released even a little. Seems worse than when I started.
I'm kinda stumped, it has spark, fuel, compression is 145-150 psi. I haven't drilled out the covers for the mixture screws, not sure what to do next. I've got lots of old stuff running, this one's almost new and won't run. Always starts right up with choke and fuel on.
Since I know nothing of the prior history, it looks all stock. Maybe this is why it was parked for so long, dunno.
Any suggestions would be appreciated.

Update.......Took off the carbs again and drilled out the brass covers for the pilot jets, and one was open 1 3/4 turns and the other only 1/4 turn! How this could be right from the factory? So I open them up both 2 turns and reinstalled them. Won't start without starter fluid. Checked for gas in float bowls by opening drain screws, no gas. Hmmm. Must have gotten crap in them when I bypassed the fuel pump and filter (which works as it should)
So I'll have to drain the tank again, clean the carbs again, and try again. At least I can do it quickly now since I've had so much practice.

RE: Idles for a while, dies if choke off or throttle opened
yeah sat that long proly all kinda crap in that tank, need to drain, then theres a solution for cleaning it, may need new fuel lines and filter too as this new fuel leaves a film after sitting. will see if can find the solution to use in the tank, helps clean it good.

could also just rinse her out good, take a good light to check inside the tank for rust issues, if there is some there is a tank liner that can use to help with that to keep it from getting into the fuel, otherwise worth a shot after checking to add your fuel then a full can of sea foam, crank her over like trying to start her up so fuel gets through the lines good and into the jets hopefully, then just go away, try it again in about 2-3 days, have heard of barn finds starting up like that.

RE: Idles for a while, dies if choke off or throttle opened
I got it running real good! Thanks for all who helped. Turns out the last problem was the float jets were stuck closed due to some white crap in the little bores. Seemed to work good the first time I looked at one, apparently I forgot to check the other one which was really stuck. The first one was hanging up too. Stupidity strikes again! Needed needle nose pliers to pull it out! Apparently these bike won't run without fuel!
