Petrol in Vac Advance Line


Recommended Posts

While lookling around the board in prep for de emisioning my brat, GD told us that it was good to blow thru the line to know exactly where they go (its a maze in there). When I blew thru the hardline where the vac advance on the dizzy connects petrol came out too. This hardline is controled by vacuum valve and is also conected to the charcoal canister. And gets its vac source from ported vac off the carbi.

 

1. Could this happen when the carbi floods or something?

 

2. Or is it caused by a bad valve charcoal canister?

 

Cheers :drunk:

I have seen liquid gas come from the float bowl vent line, and that goes directly to the charcoal canister... could be the source of your problems. The canistor was a big source of vacuum leakage on my Brat, so I just disconnected it. The canistor does nothing for your emmissions while operating, so you can remove it completely, and block off all the lines. The float bowl vent I would leave open at the carb... maybe put a line on it, and run it down towards the ground like the radaitor overflow.

 

Connect the vacuum advance directly to the carb, no gas can get in from there... see this thread for why you should NOT connect it directly to the manifold:
