90 hp Evinrude -- Fuel Problems??

JIS1974 I just bought this motor. 1984 90 hp Evinrude E90 MLCRD It has the VRO option (there is a seperate tank for the oil.) The previous owner obviously had some problems with it; the spark plugs and coils are new. Previous owner ran it "a couple of times o 2002-06-03
gonegatorfishing Did you clean the carbs?

You might have a blocked high speed jet. Depending on the design of the carbs this would also contribute to the hard starting and lack of idle.

JIS1974 I'm working on rebuilding the carbs now. Any suggestions or tips would be helpful.

As I was removing the carbs I noticed the "clear" oil tube that goes to the VRO unit was cracked/broken. It is fragile with age. I'm not sure if it was broken prior to my tugging on the fuel line... It needs replaced if I'm to continue using the VRO system. Any ideas where to find this part? If this was broken prior to my tinkering what would be the "symptoms" of the motor? Would they be similar to what I've described previously? Should I run a compression check to make sure there was no damage? ...sorry for all the questions; I'm new to outboard motors.

Terry H Kansas...I would definately do a compression test. You could have been sucking air instead of oil. If compression tests good I would plug the vro where the oil line hooked into and primix some fuel and run thata way until you get the bugs worked out, then if you like the vro feature get it working properly and use it.
Sounds like you do have a fuel delivery problem, check all the little crevices and holes in carb make it spotless. Check all the spark plugs for good spark and good clean plugs...if all is good run it on premixed fuel. If the problem stays try pumping the primer bulb when motor starts to slow...if that helps you might need fuel line parts or fuel pump...just a Thought
