Got 'er done! The carb had no room to rotate but I was able to remove it (somewhat difficult) and check the jets. You nailed it...all jets were fine EXCEPT the pilot jet, which was completely blocked. Spraying and soaking didn't free it, I had to run a thin wire through it and then follow with soak and spray.
After reassembly, it still didn't want to run past idle, I had to "tease" it up to high rpm a little at a time in bursts (which previously I could not do at all). Eventually it revved up and after a short ride it was better than before the problem. Got 80 mph out of it.
Actually, every year on first use I had a milder throttle problem for a while. It must have been sticky all along and recently got worse. Problem seems solved now. Many thanks from this total newbie!

Friends,
I have a BV200 which has not been ridden for a few years. I am getting it cleaned up for my wife and found that it would start, and it will idle for 2 minutes or so, but it the throttle is turned even by a very small amount, the bike will immediately stall.
I removed the right side and disconnected the output of the fuel filter. I found that there was plenty of fuel being delivered, so I think the pump, filter, etc. is all OK. Also, removing the fuel cap made no difference so I see no venting issue. Plus and ignition seem fine as best I can tell. I have replaced the fuel with fresh and tried to run some Seafoam through it, but at idle this isn't much.
Does this leave just the carb as an issue? Varnish buildup? I am definately not an expert and would not want to remove the carb and break it down without some good instructions, which I have not found. Can I clean this to any worthwile degree while on the bike? Is there another likely problem? Can anyone point me in the right direction to solve this?
Many Thanks, Drew
