Been looking around on the forum here, and it looks like a gold mine. I've just picked up a New To Me 1990 DR250 from someone, I pulled the carb out and cleaned everything. P.O. said that he already had it out to clean it up, but that he could only get it to run run on half choke, AND the fuel literally ran right through the carb. After I cleaned it it will now run, but I think that the pilot screw is not set right, if I let it run, the exhaust ends up glowing red hot by the engine. I've turned it back a bit and it seems to have helped. What is the standard starting point for this? And is there any other jets or anything that are adjustable?
