JD 3020 Zenith Carb

[ajhbike]

Had a leak on the carb and figured it needed a cleaning and some going through. Ultra sonic cleaned it out, got a gasket and small parts kit and was putting it back together. I saw that the gas inlet had been braised or welded and saw a very small crack. Cleaned it out and put some JB weld on it. Next day put some tape on the fitting and screwed it in. Put everything on and the leak is still there. Researched it and THEN learned not to put tape on since that CAUSES CRACKS!

Should I really be using a metal gas tank repair compound or just more JB Weld after cleaning that stuff I put in?

A pipe thread fitting is going to put outward force when it tightens, with or without Teflon tape. Gas will wick though even minute cracks, you may not get it to seal. Replacement may be the only way to have a good seal.

It can possibly be cleaned up and brazed or replaced. You aren't going to patch it with any compound.

Tear apart carburetor and clean the top half around the inlet fitting crack.. V out the crack area.. Preheat the crack area and braze... Tape out the internal threads for the gas line fitting.. A little no-1 permatex on the threads of the gas line fitting and screw in... Let dry..........

The other alternative is to JB weld the threads of the inlet and the fitting and permanently seal it I guess. I would have to cut the inside screen I guess because that fitting would be a one time deal.
