fredges Posted August 2, 2015 Report Share Posted August 2, 2015 So the carb on my 1300 in my '69 521 is leaking, and stinking up my garage when I park after driving it. I noticed bubbles on the right side of the window, and it's moist with gas along the seam where it meets the manifold. Where should I start? New gasket? Guessing it's not that simple. Here's a photo: 1 Quote Link to comment
datzenmike Posted August 2, 2015 Report Share Posted August 2, 2015 Try tightening any external screws on the carb that join the top (air horn?) to the body. There are several on the bottom holding the throttle plate to the underside of the body but thecvarb will have to come off to get at, 2 Quote Link to comment

Eomund Posted August 6, 2015 Report Share Posted August 6, 2015 Might need a new seal for the window too. You can try tightening the screws as a temp fix as mike said. Also, these trucks are notorious for working the bolts in the carb loose on the base. Give the whole thing a once over and make sure it's all nice and tight. 1 Quote Link to comment
Eomund Posted August 6, 2015 Report Share Posted August 6, 2015 Or.... You can shelf it and get yourself a weber. Just an option, one that I took and am quite happy about. 1 Quote Link to comment
fredges Posted August 11, 2015 Author Report Share Posted August 11, 2015 Thanks guys. I tightened everything up, and it's not as wet and doesn't bubble. However, I'm still getting strong gas odor when I aprk sometimes. I know the carb is kinda wonky, but I find them about as complicated as vaginas, I'll just keep poking at it until I get it right. HA! I made a joke. I don't want to get a bigger carb if I don't have to. Like using the old parts if I can. 2 Quote Link to comment
