Gas to Carb

[miloman]

I just finished putting my carb back together and cleaning it on my 200es but after putting it back on I can't get any gas to flow into the carb? I know for a fact that all the line is clean and it will come out of the petcock so any ideas?

Could my gas line not be like in the right position or something??

If gas is flowing from hose when petcock is on then your float or needle inside carb is not allowing gas inside. You need to pull carb back apart and make sure the passage where needle is not clogged. When you say you cleaned carb what exactly did you do? Did you remove jets and needle/float and blow air through all passages to make sure everything is clean?

I got gas to flow to it but now the thing won't start (it did before the clean)

I'm assuming from the previous post that you confirmed that you have fuel in the float bowl now? Let us know how you confirmed. What I like to do is to open the drain on the bottom of the bowl and watch for fuel to flow out. This will confirm that you have fuel in the carb.

Did you mess with the idle adjustment screw when you rebuilt the carb? Turn up your idle... or hold the throttle partially open when you crank it.

Did you adjust the pilot screw? If you did, you need to set it back at the correct initial adjustment.

Is your spark plug wet or dry?

How I know fuel is in the bowl: I used the drain screw

Did I mess with the idle adjustment screw?: No but I replaced the mixture screw, lowspeed jet, and that thingy that I always forget the name of that hangs from the float

Is my Spark plug wet or dry?: Dry, dark black

Are you sure the slide is in correctly and not 180 out. If in backward it will start sometimes but will run wide open. Remove spark plug from case but leave the boot on and let the plug rest against engine block while you crank over to see if its sparking.

I'm using a 4164 spark plug and I just swapped it out for another one that is identical and it fired for about two seconds revved hard then died?

Seems it will only fire if I spray starter fluid in the spark plug.

The fuel hose connect to carb looks funky. Doesnt it connect to an upward facing tube behind that electric loom? I might not be following this correctly either. So ?

It corrects upwards yes, but I believe I have gas in the carb (see my previous responses) but I can't keep it running without starter fluid so I'm not getting gas somewhere

I would have to agree with fieldy that from the camera angle, it looks like your fuel line is DEFINITELY connected to the wrong spot on your carb. I'm sure it's just an illusion if you have fuel in your bowl.

If it were me, I would suspect a clogged idle circuit and I would at least pull the bowl and idle jet off of the carb. I would also make sure that the bowl is SPOTLESS and THOROUGHLY clean the slow jet.

Hope that helps.

Thank you that does help and I can give that a go tomorrow, as I said many of the jets that I put in were band spanking New except for the main jet and I'm sure they're all clean and I could try again to get the fuel line on the right way but I can't seem to find the correct way to do it to make it all go down (usually goes up at some point) and I could include pictures of my carb or maybe even reinstall the old jets and screws?

Did you leave a rag in the intake when you were cleaning the carb?

[Onetrackmind]

Unless there is a kink in your your fuel line, it will flow to your bowl due to gravity. You have to be SURE that you have a full bowl though (and it is SPOTLESS).

What about your choke? Does it fire w choke? W/out? Did you take it apart and clean its passage?

Above is what my carb looks like from the outside (fuel line is sticking up in the air and I believe the one going to the side is the vent tube? And the one coming from the bottom is the drain tube)

And below is what it looks like from the inside (notice it's wet with fuel, so I am getting gas in there somewhere) (also notice all components have been replaced except for the float and main jet)

Below once again is my float and float valve

I can take any more pictures that you may need and will leave my carb off my ATC and disassembled until I get a response

While it's off the machine, you should fully disassemble it and clean it again.

I would soak it in a Chemtool bath, then clean out all of the passages w carb cleaner and compressed air. Make sure that you clean your jets too. I like to take a strand of thin wire and work all the holes in the slow jet to make sure they are open. Make sure that your choke assembly is really clean too.

Are you sure that your fuel screw (mixture) is set to factory? That is where you need to be initially.

Is your new slow jet the same size (number) as your old one?

If the above doesn't help, your float level may not be set right (you are getting SOME fuel in your bowl, but just not ENOUGH).

I am doing a carb clean bath to it right now and I'll probe the holes once it's done, the mixture screw is set to 2 turns open from fully closed which is that factory setting that it says in the manual and the jet number is the same (the number is 38 on both) and I can't find any resources on how to set the float height??

You can't set the float height on that carb. It is what it is. Notice no metal tang on the floats.....un adjustable.

[Onetrackmind]

Yep...good eye Obe Wan.

You can check float level w the carb off of the bike, but you will need some clear tubing that fits your drain line.

Fill your carb w gas though the fuel line with your clear tubing connected to your drain. Hold the clear tubing vertical next to your bowl and open the drain screw. The level of fuel in your tube will be at the same height as it is in your bowl.

You may need to add more fuel to account for the volume that went into your new drain tube...
