I have found the oil seal for 10 bucks. I just don't know how to pull the old one off. I have changed oil seals in brake drums and I have whacked them off with a screw driver. then I put the new seal in with a pipe approximatly the same size as the new seal and tapping it till it goes in. Anyone every done this before?

Thank you so much. Oldgitonabike, you are amazing. I looked at your diagram and sure enough both the air jet and the pilot jet were clogged. I know I cleaned the pilot jet out the first go around but I did not get the other jet. they were both plugged. I put a fuel filter in the fuel line. I blew it out with some air and she runs excellent. Thanks again for your help.

I have a 1980 DT 175. The kick start was slipping and I tried everything I could think of to tighten it. I did not want to pay the $75.00 for a new one. I went to a bike boneyard and found another one for a few bucks and put it on. It still slipped so I figured the shaft was the problem. I have a welder so I welded it on to the shaft. Now to my suprise, I have ruined something else. Oh well, this is kinda how my life has gone so far. But anyways, I believe what I did was fry the oil seal. It seems to be leaking from the oposite side of the kick starter( The left Side) maybe where the spocket comes out. Anyone replaced the kick starter shaft and the oil seals in a DT 175? P.S. I only ride it hunting once or twice a year so I can add oil and I am still in good shape.

The bike is cold. I went out and pulled the choke out and it started right up and seems to run with the choke out. As soon as I push the choke in it runs really well for about 10 seconds and then dies. I will look at these two jets. I am assuming the pilot jet is the main jet that picks up the fuel. P.S. Thanks for your directions on the float adjustment that I found last Saturday on this site. I was not a member at the time but it definitely stopped my fuel leak.

I have a 1980 DT 175 that has worked really well for me. It has leaked gas for several years and I have always just turned the gas valve off. However, it has slowly become harder and harder to start. The air filter was very dirty and I hate to admit it but It hadn't been changed in several years. I replaced the Air filter with a new one. I replaced the spark plug as well. I then cleaned the carburator out and put it back together. I replaced the needle and seat since I was sure this is what was causing the leak. After I put it back together, I was getting tons of gas comming out the exhuast pipe. I readjusted the float to 21 mm and this stopped the leaking. I adjusted the air intake to 1 3/4 turns from closed position. It now starts up on the first or second kick but you have to keep it going by constantly giving it gas or it will die. It really boggs down and you have to basically gun it to keep it running. I took it appart again and found some small rust flakes from the gas tank. I cleaned the carburator out again and put it back and it did the same thing again. I can't see a piece of rust getting back into the exact hole or spot to make it run poorly again. I am going to put an inline filter on it and try it again but any other suggestions would be helpful. Thanks
