  1. I was lucky and found a used OEM. The other stuff I have no idea. All I know is I bought an supermarket one new off ebay for my sons Polaris ATV and it was junk. It wasn't a mikuni though. I would think that would be fine. Hopefully someone will chime in.
  2. I got luck and found a used carb on Ebay. The guy said it was good and guaranteed it. So I bought it. Put it on and had to tune it a little other than that. I was good to go.
  3. Damn... It did't work. The tube seperated at the base of the carb. Guess. I need to look at a new carb. Ohh well. At least I tried.
  4. yep that seems to be my problem as well. The pilot jet. This should be interesting to get cleared
  5. im on the same page as you.
  6. Thanks, I'll give that a try. Here is a picture out of my book of what I am talking about. It is the brass tube next to the one with the arrow. It is the one with a tiny hole. Should that be clear. I would think so, because it would have to serve some kind of purpose. Thanks
  7. I'm still working on mine. The little brass tube that is pressed into the carb body. Is that supposed to have a passage to the carb body. If you are not sure what I am talking about. I'll post pictures. I can't seem to get anything small enough to put in the hole of the tube to find out if it is blocked or not. I definately don't see light. And it is pressed in the carb body so I can't remove it.
  8. I purchased this bike a few months ago for my kids. It sat for a few years. So much in fact that the carb was dirty. I pulled it appart cleaned it the main jet looks good. I can see through it. I pulled the gas tank and had to remove what was left of the fuel screen. I cleaned the tank put in a new fuel screen and also a filter before the carb just to make sure. I put the carb back on and I am having trouble tuning it. The fuel screw is 1 1/2 turns out. The idle screw I have no idea. I can start the bike. It runs however when I twist the throttle practicaly dies then revs up. It also seems to take a little while for the idle to come back down. Anyone have any ideas?

    CRF50F fuel/Carb issue.

    I took the Carb apart today and cleaned it. I need to check to see how many turns in the 2 screws ar on the side. For mine. I think the top screw was 5 turns in and the bottom philips head screw was like 8 turns in. My Screen for the tank should come in the mail Monday along with some other odds and ends. I probably should have bought the entire fuel petcock, as the one I cleaned out was horrable looking and I don't even think the reserve feature works on it at this moment. It was caked will all kinds of grime old fuel and plastic from the old fuel screen.
  10. Like many others on here. I just bought a 05 CRF50F for my son. It sat for a long time. I pulled the tank, and emptied the gas. It was nasty. The fuel screen in the tank was distroyed and clogged the fuel lines. I was wondering. Would eliominating that screen and putting an external inline work just as good? The next questions will come later when I pull the carb appart. I got it off, and pulled the bottom off. It also is very dirty. So it looks like a lot of jet turn counting and cleaning is needed. Hopefully that is it. Thanks guys/girls
