Re: Carter Carb fuel leak

Hi John,

I too am dealing with a leaking Carter WA-1. The rebuild house where I purchased the unit told me that if there was positive pressure on the throttle plate, gas could siphon back down the throat of the carb and leak. When I checked this out, I found there WAS too much adjustment on the linkage and, in my case, not enough threads to alleviate it. Not knowing the history on the linkage or where it came from (when I got the car it had a Carter carb from a Chev Bel Air 6 cyl) I ended up cutting a piece out of it and brazing it back together. That worked perfectly as I was able to adjust the idle down to zero such that the motor wouldn't even run. I then brought it back up to 'spec idle' thinking the problem would be solved but it still leaked, dripping out the bottom of the bowl. This winter I removed it and took it to a carb specialist here in Canada. He rebuilt it (although it was SUPPOSED to be a fresh rebuild from Carb-X in El Monte CA) and reported numerous issues with it, including parts that had not even been removed during the last rebuild go-round. He said he machined all the surfaces (whatever THAT means) and the unit is ready for pick-up with a bill of about $240 USD. In that this is the second carb I have purchased for the car at $350 each and now this rebuild bill, I HOPE the damn thing doesn't leak!!! Does this sound anything like your issue?? Chris.
