On to the next problem 1983 470merc 170hp

i put an alternator conversion kit on i winterized motor and stern realized another problem boat is hard to start meaning no gas in carb (only when sitting for a period ) when i tried to start motor to pump antifreeze in it would not start and battery went dead charged back up still would not start i poured some gas in carb started right up and ran great. so does this mean i got a carb problem do i need to rebuild carb or is the fuel pump not working properly why is the motor hard to start when sitting for a period

p.s. boat was hard to start on other occasions not just winterizing but battery held out enough to start and gas got to carb is there a way to choke the carb or do i have a problem mentioned above

It sounds like the fuel bowl are slowly draining out over time. Have a look at the link below on carb rebuilding by Alpheus. It mentions in one of the videos in the rebuild about leaking bowls and what you can do to repair it.

Run a pressure test on your fuel pump.. May have a stuck float in the carb.. Once you get it running will it stay running?

my carb is a 2bbl the guy said in the video about putting epoxy on the two plugs to stop bowls from draining, the carb in the video is a 4bbl will my 2bbl have the same plugs

I had somewhat the same problem after my boat sat for a while. I solved it by putting a squeeze bulb on my gas line anout 18" in front of my carb. Before I start it after it has been setting a while I give the bulb 3-4 squeezes and it starts right up. Worked for me.

No. And there is no need to epoxy anything on a Q-jet built after 1967...drop the JB Weld and slowly back away...

ok on epoxy but why does carb leak out gas from bowls does this mean carb rebuild will this solve the problem
