"Hello everyone,
I recently purchased a 7.5 Mercury outboard in excellent condition. I was amazed to find out it is a 1975 year from its serial...it's in that prime of condition. The individual I bought it from had it stored indoors for the last 5 years. He couldn't get it started and just wanted to get rid of it. Sounded to me like an issue with the carb so I jumped at the offer.
He said he could get it to turn over, but only at full throttle and only for a little bit until it choked out.
First off, when the fuel bulb was pumped, gas would come out the carb. This was an issue with the float. I pulled off the carb and took a look. Didn't see anything wrong but cleaned it up and put it back together. That issue was resolved so the float is working properly.
After that, still gas would come out the carb when trying to start. Not a lot but I dont think it is normal. Still, we couldn't get it to fire at all. Someone suggested it could be the fuel pump diaphram. I bought a gasket kit for the fuel pump and changed it out. Still nothing, there is still a little fuel that comes out the carb but not as much.
Even if you flood the engine are you ever suppose to see any fuel come out the carb? I wouldn't think so....
Any suggestions? I have spark. One thing I found odd was that after trying to start it for a while and pulling the plugs, the inside of the cylinders seems relatively dry....I would suspect quite a bit of fuel to be inside after seeing how much would come out the carb.
Any help would be great.
Thanks"
