My 1996 25hp motor has been hard to start. It always started but it took several tries.
I noticed that the manual primer fuel line that runs to the top of the carburetor was routed behind the starter motor and appeared to be pinched. When I disconnected the line at the carburetor and pumped the primer, no fuel came out. The fuel line that runs to the engine block below the carburetor has fuel coming out.
I installed a new OMC fuel line running from the top of the carburetor to the tee fitting, and I replaced the fuel line from the tee fitting to the engine block with a longer line to give me more room to work.
It was a tight fit getting the new fuel lines on to their barbs. I cut zip ties off the old lines but haven't replaced them yet as I don't know if I'm finished yet. There isn't any leakage at any of the fittings when I pump the primer.
The motor hasn't started since making this change. The first time I was pretty sure the engine was flooded, so I pulled the plugs, cranked the engine a few times, and left it overnight to dry out. The next morning when I tried it, it fired up but I didn't run it for long. I took it to the river for an extended run, but it wouldn't start again.
I suspect I've flooded it again but it's hard to tell there is fuel being delivered to the engine when I prime it. If it doesn't start after a few tries, I reprime.
Do those fuel lines need to be zip tied to work properly?
Am I on track with this repair?
Thanks
