250sx NOT STARTING!!!

Put a wrench on the nut that threads it onto the tank. Tighten it. now keep the wrench on it for back up, to keep it from spinning. Now put another wrench on the bowl and take it off. it should break free and un thread.

Ok take your carb off completely. Take it all apart, clean everything with carb cleaner, then put it back together according to specs. Talk to DeePa about an online manual that you could refer back to. If not, get carb cleaner and just spray the hell outa the carb. This should loosen everything up. Bolt the sucker back to the engine and hook up your fuel lines. A problem might be that your petc0ck might be clogged up so check that. Another problem might be that your gas cap might be plugged so take that off and try to start it without it. Good Luck

I was thinking buy a can of carb. cleaner. I don't know anything about this situation so tell me if I am wrong to do that.

[firefirefire90]

Clay...should he not emty the tank before doing this? If he does it all the gas will out?

EDIT: Use B12 Chemtool. This worked perfectly for me for carb cleaning.

[ClayW]

Not if the valve is in the off position off. I would try the petcock valve first.

[SPECK]

I know nothing about engines, so taking my carb. apart may be a bad idea. How is carb. cleaner applied? Anything need to be taken apart/off?

And I will try once again to remove the "petcock"
Also I will try the gas cap thing.

[ClayW]

If thats the case, you should definately pull it as a last resort.

[SPECK]

DO you need to take anything apart to use carb-cleaner?

Ok im on a computer where I can type fast now. I was using a tablet PC. Anyway. Did it run before and just start having this problem. If so its rust from the tank guarenteed. Especially if it fired off with a shot of gas directly in the carb. Choke isnt going to make much of a difference at this point. Clean that pet cock out. Hold a wrench on the upper part for back up. TUrn the valve off, and put a pair of channel locks on the bowl and unscrew it. Its likely full of rust, which will not allow enough or any gas to get to the carb. Hell take the fuel line loose from the pet cock and turn the fuel valve on. See if gas comes out. That will tell you something too. Clogged or not. Hope this helps. Dont yank the carb unless you have too. Its very time consuming to say the least and you need to have an idea of what your doing.

[firefirefire90]

just open the valve on the carb and spray it in
then open the little hole on the bottom to let it all out. No fuel=carb/tank

If you end up having to check the carb you wont have any trouble. Very straight forward. If you need help we are always here.

[Erics350x]

try removing the fuel hose from the on\off valve. then turn on the gas. if gas comes out you will know its the carb and not the valve/petcock. if it doesnt take the vavle off and clean it out.

[SPECK]

I called my father, the original owner of this trike.

He said:

Pull off the line from the petcock and then turn the petcock to the ON position and if fuel comes out then that is not clogged. If it does not come out, then take off the bowl underneath and clean it.

If the petcock isn't the problem, do this:

Buy carb cleaner. Remove the same line as above, spray it into that line. Hook the line back up and kick-start it 2-3 times then let it sit for 15 minutes.


He said it is 1 of these 2 problems he can almost guaruntee.

Thanks again for your help guys and I will report to you again tommorow. It is 11:20 PM here in The Great Northern Michigan so I am done for the night.

Ok, so I purchased the GUM-OUT carb. cleaner and will apply that AFTER I try the petcock, I just got back from town and am now able to do it.

We'll see how it goes.

How much gas is in your tank? I had the same problem you did, and I could not figure out why it wasn't starting. I shook the bike, and gas sloshed in the tank, so I figured that it was not a "low/no gas" problem. Checked everything I could.. no go. I was stumped. Finally, on a whim, I decided to turn the petcock to "Reserve" and see what happened. Well.. she started right up after that. So even if it seems like there is gas in your tank.. there may not be enough to go into the tube on the petcock.
Put some more gas in the tank before you do anything else.. sometimes the simplest things are the most overlooked.
