Banshee not firing on one cylinder

[Schrader]

My banshee would only fire fine until I hit a higher gear then the right side would shut down and fire every once in a while. I took carbs off cleaned them put them back on now it doesn’t fire at all it will blow smoke sometimes and back fire it is leaking out of exhaust and getting gas I’ve swapped spark plugs, wires, carbs hasn’t changed it has the tores delete idk what else it could be

Flip it up n see if the pipes are full of fuel

Just did that a little bit of fuel cane out it was black 

[375hp banshees]

Might just be flooded, see if new plugs are wet, kick it over with them out (WITH IGNITION OFF) to get as much fuel out of cyl as it will blow out & try & start with fuel off. If it starts turn fuel on & start diagnosing all over

It will run just the one side won’t fire I don’t think it’s spark or fuel because I swapped everything and the left side still runs strong

Put choke tube back on, slides in correct carb? Compression test?

case can still be flooded on one side, and not run on that side

[Schrader]

I didn’t know the slides matter what carb you put them in I tested compression I got about 105 in both I don’t think its flooded because it started right up and was running one on cylinder. I don’t have the choke tube hooked up though could that be it

Put choke tube on & iirc the cutout on the bottom of the slides face the back of the quad & try it

Was the choke tube off before or just since youve been working on it?

105 is low but doable & since other sides the same & fires...plus could be gauge

[Schrader]

Put the choke tube on didn’t make a difference when I first got it I put some stock carbs I got from a guy and I never hooked up the choke tube and both fired then it sat for a while and that’s when the right cylinder started to stop firing it shouldn’t be the carbs though because I swapped them and I just swapped them back and put the tube on and I think since both sides were the same it might not be accurate but they are both consistent

So you poured gas out of the pipe but don't think it's flooded?

[375hp banshees]

Oh, you swapped them side to side, not with another set.

I cant remember if leaving the tube off causes a lean condition.

If you swapped carbs & plug wires side to side i' d lean towards mechanical, maybe inspect reeds next easiest. Tho 105 is pretty low everything would have to he spot on for that to run well i'd think, i assume you didnt do comp. Check when you got it?

leaving the choke tube off will leave a large enough air leak that the carbs won't be able to draw fuel and start at all.

Kicking while on end should flush out cases wont it ( depending on pipe bend& being able to exit pipe)

I've had to completely remove them and turn the quad completely upside down with the spark plugs out to get raw fuel out from flooding
