Thank you for your help. I’ve done basically everything you said besides comparing spark plugs. I have those tools in which I did use to clean out the carbs and each jet. I did test the fuel pump by keeping the drain bowls out of the carbs and turning the engine over it did pump fuel into carbs.
Checked spark and compression both are good. I do have it to its own tank. Not the boat tank. I took the drain plugs out of the carbs and cranked the engines and they were filling. I will try what you said and pump it. I replaced all filters and checked all of the lines they are all clear.
I have a 1990 Johnson 140 vro outboard that has been siting for 2 years. It was properly stored. Im having a hard time getting it running.
I replaced the following
- fuel pump
- compression is 125 psi
- new gas
- check all fuel lines no blockage
- cleaned out all carbs. They were very clean...
