I recently acquired a seized 8hp, the motor had very little use and was left in the engine room of another boat for 2 years laying on it's side. After unsuccessfully trying to unseize it using conventional methods I decided to rebuild it, the crank shaft bearings were frozen and I was able to clean them up and put the motor back together. I am at the stage where the motor should be running but I can't seem to get combustion.
I am getting 120psi compression from both cylinders and I am getting spark at both plugs. I rebuilt the carburetor which had a lot of dried up gas in it.
I could not get combustion even when I sprayed starting fluid into the carburetor.
When I rebuilt the motor I didn't pay attention to the bleed hoses and valves, when I pulled the lower hose off fuel poured out of the fitting and I'm not sure if this should happen? I am also not sure if you have to set the timing on these motors? The service manual I have is not very informative regarding timing.
Any thoughts?
