Pods wont make a difference either way.
Pods off; Do this, take a spray bottle, fill it with a bit of gas, shoot it in the carbs when trying to start it, you might have to turn the throttle a tad. If it starts or stumbles starts you are lean yo! Or clogged carbs/jets.
P.S. be careful with doing this. Also make the the garage door is open and don't face the exhaust or the carbs in case of a back fire.

Not a bad idea just requires more tuning. If the bike sat for an extended period of time with old gas in the carbs then they will be clogged. If the bike starts on ether then you know the ignition system is at least firing. Did this just come on or was the bike stored? If stored then take the carbs apart and thourghly clean them paying attention to the idle circuit and all it's small passageways.

+1 The slide sits all the way down at idle anyway so the diaphragm is doing nothing there.baldy110 wrote: No, torn diaphrams will not prevent the engine from starting. In fact you can remove the diaphram and it will start and idle. It will not allow the engine to run past idle though.
I patches slits in my diaphragms with urethane (gorilla) glue but that's not why yours won't start.

VACUUM LEAK.crabman02 wrote: i have spark, and the boots arent cracked or anything, and i have installed a new float needle and gaskets for the carbs. i got it running once off of ether but it was really loud at 5000 rpms idle :pinch: any clue what it could be?
I would clean the fuel system top down (tank, petcock, carbs) then install inline filters. Check/adjust fuel levels in bowls using a clear tube.
If you can get it running, check for vacuum leaks.
