getting a bike running

[mrdj115]

Alright. There was a screw directly opposite the nipple. It was the only one even close so I assume it was the right one. When I opened it up, no gas out of the nipple. What's next?

Turn the petcock back to On or Run, then disconnect the fuel line from the carburetor. Find a suitable container, stick the end of the fuel line in it and turn the petcock to Prime. If gas comes out, your carb is going to need to be disassembled and cleaned out. If no gas comes out of the tubing, the tank will need to be drained and the petcock will need to be removed, cleaned and/or rebuilt.

Gas flows through the petcock fine. It's definitely the carb.

I took the carb off and took it apart. There are a few screws that I left in. Two of those screws go from the bottom of the carb (near the plastic floater things) into the center of the carb. There is another screw that is not near the floaters but I can see it in the center of the carb also. Do I need to do anything with these screws?

Also, on the bike the carb was attached to a fairly large plastic cylinder. Inside the cylinder looks like metal mesh. I'm guessing it's some kind of filter. Does this need to be cleaned? If so, how?

*Edit - I think that cylinder is the fuel filter. I took it out and it's really dirty. Should I try to find a new one or is there a way to clean it?

Ok, quite a few updates.

First thing...I want to thank all of you who have been helping me along the way. There's no way I would have gotten to this point without your help. I really appreciate it.

My cousin found the operator's manual. It doesn't have any major information but it's helping a great deal in tuning things up a little.

I found out that the plastic cylinder thing is the air filter, not a fuel filter.

I took the carb off and disassembled it. I found an extremely helpful diagram of a carb online (http://www.dansmc.com/1stdcarb.jpg). I used that as my guide (along with the explanations on that site) and cleaned the whole thing with parts cleaner.

After I put the carb back on, it still wouldn't start. A little starting fluid and...YES!! I was so happy when it started.

Now that it's running there are a few things I need to get straightened out to get it running better. I don't know how to check the idle in order to set it correctly. The clutch is pretty rough (although this could be due to the fact that I am an extreme newbie). I'm gonna have someone with more experience tell me how they think it feels.

And this is the one that confuses me the most...if I pull hard on the front brake, the engine dies. Any idea what that could be?

Hello Matt, and welcome to the forum. These people haven't been here in years. You'll have better luck going to the introduction or garage areas. Good luck.
