I cant see much from your picture, but any and all fuel leaks should be fixed at once. Unless you like things going BOOM on the back of your boat
hope your fire extinguisher is in good shape

Screw # 25 has a constant drip every 20 to 30 seconds. What can I use to stop this leak, Teflon tape?

I just finished cleaning all 3 carbs and installed items recommended: inlet neddle #6,7,8,33, blew it all out with compressed air.Reinstalled them (3 carbs) and when I pumped the primer bulb gas spray right out of the carbs. So I am in the process of adjusting #4,5 as per the repair manual. Measure 3 x's and hope for the best. Looks like its gonna be an all nighter.

Oh by the way I found a red plastic tube the kind used to attach to an aerosol can behind the middle carb it may have prevented #20 from closing properly.

I wrapped it (screw #25) carefully with Teflon tape filled the bowl with gas left the float out and put the cover on, to test it..!! Should know if if gonna leak in a few mins.

OK it stopped leaking. Not a drop and when I pressed the primer it was very firm less than 1 pump. 7:30am its time for bed....I'll start her up later.
