My buddy has an ‘89 90HP V4 that runs (ran) like a top. Was winterized in fall. This spring, was stalling - ignition wire was cut, probably running on 3 cylinders.
Installed new ignition wires. Starts great. Idles great. Runs to 2500 rpm’s fine. Then dies. Checked spark at each plug. Plugs could definitely be replaced. There is no water fuel separator or a pre Fuel filter before fuel pump. Screen at fuel pump is clean. New fuel. Fuel line and primer 3 years old.
Going to replace spark plugs. And, pull carb. cowling off and spray carbs with gum out.
Thoughts where to focus ?
