MG MGB Technical - MGB Dashpot oil leak

I have a 1974 mgb with SU-H1F4 AUD550 carbs, the rear carb dashpot will not keep oil, it is leaking out bottom onto jet needle, is there a sealer and repair procedure to seal bottom of dashpot oil well ??

Thank You

Are you saying that with the piston out on the bench, when you put oil in it leaks out of the bottom?
Allan Reeling

Hi Allan, when on bench oil will seep out of hole were needle was removed from.

That's a rare one, will have a look at an HIF tomorrow and let you know what I find.
Allan Reeling

Should not do that, it was overdrilled from one end or the other. Clean off all oil and put a bit of epoxy in the bottom of the damper tube or the recess for the needle, not getting any on the sides.

Hi Allan & FRM: After complete clean of piston dashpot I noticed small hole in center. I use JB weld to seal hole. I used a plastic drink straw to draw sealer in straw and inserted down hole on plunger side. Applied a little breath into straw and slowly pulled straw back out. Process worked just fine. Thanks for all your help. Jonathan
