Hello, I am new to the forum so i hope im doing this correctly. I recently was given a 19 ft sea nymph with a 93 120 hp Evinrude. It had sat for 6 years and had not ran for that time. Once it was home i put new carb kits and new plugs Flushed the fuel tank installed a new fuel water separator, Deleted the VRO and premixed at 50 to 1, flushed all the old oil and fuel out of the pump and added new fuel lines. Took it to the lake and she jumped right to life but seemed to run a little rough after about 30 minutes i pulled the plugs and the bottom left plug was dry. I did do a compression test and all 4 cylinders were between 120 to 125 psi. the plug in question is firing i made sure of that as well. any help you be great.
Thank you.
Thank you.
