1981 750F Carbs

[hosedragger105]

I'm currently finishing up an 81 750F. I'm having issues with the bowls leaking out of the drain when I draw vaccum on the diaphrams. The drain screws seem to be completely tightened down yet they continue to leak.

Ideas?

Thanks.

I have the same problem and can't figure it out. HELP !!!!!!!!!!

I dont have these carbs so this is just a suggestion.
How about getting small fuel resistant o-rings and putting them in the drain. When you tighten the screws, you should get a seal then.
