Does your carb have 2 adjustable screws?
Some have 1, Some have 2 (one high speed + one low speed adjustment)

It starts with the starter... So it is pulling fuel and sparking.
What's your fuel mixture?

Is it a used X1? or Brand new? Though brand new or not they sometimes come abit defective.
Try to start it with the idle screw or low speed screw all the way in, take care when screwing it in, hold the throttle wide open with the bike off and screw it in gently and don't tighten it to much just until it gets tight otherwise you will mess up the small threads. the reason to hold the throttle open is sometimes the slide can bend that screw on you when you screw it in all the way so hold it open and screw in that screw. Try to start it with the screw all the way in AND HOLD ON it will take off on you if you aren't holding onto it when you start it.
If it idles like that back it out 1 1/2 turns. If it still quits then you have a part somewere to clean or replace.

The rubber pump diaphram my not be pumping enough gas is what sounds like. Choke systems might start it even if the carb is bad. Might need to adj. the low jet inside the brass ring on top.
Sounds like he has said he has tried that though. Try to give him a starting point on it were it should run then he can fine tune it more if necessary.
Like for instance how I set idle screw, is start all the way in and back it out till its were I want it at. That way it is guaranteed to start for me and then be adjusted from there.
Instead of starting with the idle screw all the way out were it doesn't start and messing around with it.

The Flat head one with a spring is the low speed adjustment. The other would be high speed.
The low speed is also idle, and it does slightly affect the high speed adjustment but not by much.
If the bike doesn't start with that low speed screw in all the way then you do have another issues either with not enough fuel, to much fuel or something letting in air somewere causing not enough fuel.
It isn't always the carb that goes, sometimes gaskets and the plastic manifold can break.
(take care with the low speed screw in all the way when it does start it will rev up and want to start driving itself make sure ur holding onto the bike inscase.)

When cleaning the carb. Did you soak it then use a air compressor?
You'll need to blow out the passages and the jets with an air compressor after you soak them.
Don't soak rubber seals or gaskets they will get wrecked.

Any compressed air should work I guess an air compressor might be overkill. But soaking alone isn't enough.

This could be it.
That could be from something being still dirty. I don't think those carbs go as far as to have a pump speed/flow adjustment do they? A flow adjustment wouldn't make sense as the bike sucks the fuel its not meant to be shovelled fuel by a pump.
So a clogged passageway? or incorrect screw adjustment. or leaky gasket.
Leaky gasket could prevent enough fuel from being fed to the engine. Especially reed/manifold gasket it will suck air and not take fuel.

Ok it should be clean enough to run.
EPR hasn't gotten back, He might be onto something with it not pumping enough fuel for the bike.
Choking would force some extra fuel but you wouldn't be able to ride the bike like that.
EPR - How would he increase pump flow? As I said I don't think these carbs have a adjustment for that. Not one that I see on my brand new pumper carb anyways. How abouts his fuel filter itself? clogged or backwards filter installation.

Have you tried with the idle screw out 1 1/2 turn (from all the way in) and the high speed out 2 turns (from all the way in). And with/without choke? if it has manual choke.

Spark, Fuel, Compression = It will run. Perseverance is key.
My last mishap with my bike starting then idling down and dieing was all from a cracked intake manifold.

Sweet Cam2.
Uhm on mine right there its just white.
It does seem like I can peel off whatever substance is there. Is this normal that a screw would be hidden?
Mines brand new and works fine as it was from the store but looking at your picture and mine it looks like my screw is covered up.


EDIT; Curiosity got the better of me, I figured it wouldn't hurt so I poked at it and it was some sort of waxy substance. And indeed it was hiding a screw :eek:

So CAM2 Im still woundering why Tebow_Man might have to do that adjustment.
His bike was working for him at his current settings, He says it worked till it sat for abit then now hes trying to use it again with no success.

CAM2 what about something still being gunked up from old oil stopping full flow of fuel? He says its been soaked and blown out which shoulda solved that though.
Id figure his bike should start with its settings since it was previously running on those settings.
