Re: 340 wont idle without gas?
probably the idle solenoid, have you cleaned its nozzle and the channel into the carb?
voltage on the blue/red wire?
hear it click when you tap the wire to the solenoid?

Re: 340 wont idle without gas?
yeah but is the channel in the carb clean? (remove solenoid and blow trough it with an air compressor)
you can also blow through the emulsion pipes at the top of the carb, could be a bit of dirt in the main yet

jep, solenoid can work fine but if the channel of it going to below the butterfly of 1st barrel is blocked; or the petrol doesn't reach the solenoid you won't have idle without selfapplied throttle
Re: 340 wont idle without gas?
ok cheers will check on that tomorrow ....if it turns out not to be that any other possibilities in mind? .......think the carb wants a rebuild anyway it seems to leak fuel when gas pedal is pumped........do you happen to know where to get a refurb kit for the weber 32 dir 109??

Re: 340 wont idle without gas?
fuel leaking out if pedal is pumped; mostlikely accelerator membrame. this is the membrame that has 4srews and is placed next to the idle solenoid.
refurbkits in the u.k. i don't know, in holland you could try bccp.nl

Re: 340 wont idle without gas?
means it's running on 3 cyl, do you get a good spark at that cylinder?
if you get a good spark there; best thing to do next is a compression test
