Hi this is my first post here. Just recently purchased a Bass tracker with a 1985 140 hp Evinrude. Didn't start at first. It's been sitting for quite awhile. I drained the fuel tank,
put new fuel in,
cleaned the fuel filter,
replaced main fuel lines
Replaced spark plugs
Sprayed lube in the pistons
Cleaned the carbs
Checked all jets
Took VRO pump apart and replaced diaphrams (old ones were cracked up)
Checked spark on all plugs
Dumped in some seafoam
The plug for the VRO pump was very slightly corroded inside, and I cleaned it a bit and filled it with dielectric grease.
Result is it'll fire up, but run like it's only firing every odd time. Dies frequently. Then all at once it'll catch and run like a dream, only it won't idle down but stay very high idle. Before I replace the diaphrams it seemed to only stay running with the pumping primer bulb.
Would anyone have any ideas what to check next? Since electrical issue or something?
