OK I have the air screw at 1 1/2 but the other day when my dad and I were doing this it really didn't make a difference the bike is a challenge since of the wierd carb. Every bike I own have a mikuni with 1 air screw that is set at 1 1/2. I'll try though again. thanks for the advice and help

Hello to all who are trying to help me out. I blow the carb out with my compressor and made air shoot out every passage with getting all the water out as well and as for a picture I did get it to work so here it is. The pilot jet though doesn't it deal with the choke?

Hello DirtyDT, so correct me if I am wrong but you are saying that the screw toward the front of the carb is for the pilot. Do you have any knowledge of what the pilot screw should be set to.

Hi, I have checked all that. I have parts cleaner that I put the carb in, shot water though all of the carb jets, and blowed out all the remaining dirt. What is photobucket and is there another way to post pics.

Hello and thanks for responding back. I will shortly find how to take pictures and post them but on the carb there is the idle screw on that adjusts where the slide sits but also there air adjustment screw with another screw that is on the carb to reed valve side. And for taking the carb apart I knew I needed to since I got it home and it did what my others did before which was that they would only run with choke and I could ride without choke but I had to keep the engine reved up.

Hello, if your are putting in the 1900cc then you should be fine. I would check the oil with the bike standing straight upright. Also see if the oil might be leaking from the oil seals, drain plug, or around the case if you think your losing some.

I bought a 1979 DT 250 and the carb was all messed up. As I was taking the carb apart I found that the previous owner had screwed down both air screws. The bike needs trouble shooting, but first I need to know what the factory settting on the screws is first. Any help on the settings will be gratefully appreciated.
