Bitch on gas... Carby maybe? Help lol

[taslucas]

Id be checking and tightening all hose connections for the gas. My GQ was running dual fuel when I got it. It had a fully reconditioned carby, mixer, hoses etc. Twice over the period of 6 months I lost power with gas, also it wouldn't rev over 3000 rpm. Both times I fixed it by tightening the hose clamps on the gas line close to the carby. The problem being that when trying to get above 3000 rpm, it would begin to suck air in through the loose connections.

Does this happen after a gas fill, you could be getting an air block.
switch from gas to petrol a few times on the move and see how you go.

Could also be dual fuelling,

I'll look at them hoses. It starts fine. It gets worse the warmer the motor gets. To take off in 1st gear now I have to get the revs up to 3000rpm at least or it will stall. Changing gears is the same really. Even that doesn't always help. I doubt she is duelling, fuel levels stay the same. It can also be rougher after a gas fill also 3dogs

When a coil is buggered it can play up more as it heats up.
Also a faulty ignition module (the bit that replaces the points) can have a similar affect.
Does it feel like it's an electrical miss or is it more of a fuel shortage lag?

Hmm ok. On gas it kinda feels like a fuel shortage but in saying that the electronic ignition stuffs up on river crossings a lot. I had a bloke say it seemed like an electronic problem once. Driving on petrol some times the revs drop right off to 0 then straight back up... Like it gasps. Not as much on gas but has done before... I'm running a bosh coil

If it does a similar thing on both petrol and gas I reckon id be looking at the coil or ignition module. Can you get hold of another coil of a mate etc,to swap for a test run?

I'll try another coil if I can. Shouldn't be to hard to find one. Any way of testing the electronic ignition to see if it has issues?

I got instructions to test my pertronix ignitor. I'm not sure if they'd be the same. I posted them in the forum manuals section.

Awesome thanks mate. Not sure if it's issue related or not but it's never started on petrol from a cold start. Will once it's warm with ease but not when it's cold... Only starts on gas
