I hear ya! But if you get to the point where you think the problem is in the carbs, you have to take the surge tank out, so at that point I think its easier to just get the earshave done. I'm more electrically inclined than mechanically, so I'll let the others help diagnose the problem

Could try watching it in the dark to see if any of the plug caps/plug wires are arcing. Just found one of the caps arcing on mine.

The carb vent has the tee between the carbs. The line can run to either ear, there's a spot on both ears.

You still have the airbox, so you probably still have stock air filters. Pods are the aftermarket air filters, used when the airbox is removed... earshave.

Sounds like there might be a vacuum leak. Check both vacuum lines, to the petcock (left carb), and the emissions valve (right carb). If starter fluid gets to the leak, it will change the idle. Spraying near the carb vent shouldn't cause a change, but it might. The vent is directly into the fuel chambers of the carbs.

Jim-n-AZ And I rebuilt the petcock. It was leaking... Seems to be getting enough fuel...

Goofyfoot2001 I highly recommend the tw200 petcock mod. Takes another element out of the fuel to combustion equation.

Yes I have the pods (or ears). And yeah, I'm guessing that's where it goes. Everything I read said it should go to the right side air filter, so I was hoping that was my problem... I've sprayed starter fluid everywhere, and after tightening the rear boot, nothing else made a difference. After pulling the tank, I saw that where I was spraying between the front carb and tank that was killing the motor, was probably just a fluid induced short. So I'm back to square one...

Engine fluctuates between idling at high rpms for a few minutes then trying to die unless I open the throttle... It smells and feels like one of the cylinders is cutting in and out.

Not that I'm an emoji guy, but this one expresses my feelings...

Is this the crankcase hose?
