the fuel petcock on my 1984 fj1100 wont stop flowing gas. Even if it is on prime setting. I have installed an inline fuel shutoff valve to turn it off after i ride. After leaving the fuel shutoff valve open for an hour(engine not running), my carbs leak gas coming from the overflow hoses. My question is, is this normal? :scratch_one-s_head:
Or am I having an overflow carb?

It's not supposed to stop flowing on prime.

All other settings on the petcock (ON,RES,PRIME) wont stop flowing gas.
are you sure it has 3 settings? I think it has just on and prime
I guess it is possible that it has been changed. but you should take a closer look.
is it vacuum operated? if so and it still flows fuel in the on position (not running) than it is a problem.
but remember when you disconnect the fuel hose it can still run gas for a second or two before stopping.
I would say fix this before worrying about your carbs
Replace the o-ring on the shutoff plunger. 5mm x 2mm
