Hello I have a 2HP model 2602 Evinrude outboard that I?ve rescued from my brother in-law?s garage. Previous work had been done on the motor and others it seems were not able to get the motor operational again.
I took it on as a project and I completely disassembled the whole motor and put it back together looking for worn or broken parts. I had to replace a water impeller which I think this was what caused some of the other problems. Because the water jacket was not being cooled the piston rings got scored and these I replaced as well. I decarbonizes the piston head. The motor had plenty of spark coming from the plugs but still the engine would not fire.
I rechecked the gas tank and washed it out and cleaned out the fuel line to the carburetor and for good measure I put in an inline fuel filter I redid the carburetor with a carburetor kit and then I reset the high and low speed needles as per the manual. I seated each of them gently and I backed out the low-speed needle by 1-1/2 turns and backed out the high speed needle by ? of a turn.
I brought the motor down to the lake and fastened it to the dock, when pulling the cord on the rewind starter the first time the engine did not fire so I put on full choke and the engine would start but would subsequently begin to die and I immediately put it to half choke and the engine ran fine. However when I tried to remove half choke the engine would sputter and die.
On repeated attempts, starting on full choke would get the engine running and moving it to half choke the engine would purr nicely. I left it run on half choke to let the engine warm up and the new water impeller was doing its job fine and the engine ran fine from the standpoint that if I did not try to remove half choke I could run the engine at full power and return it to the start position and even dropping it down to slow. However touch the 1/2choke and the engine would die.
I tried increasing the high and low speed rich setting in an effort to keep the engine running without the choke. This failed and I returned to the original settings and it ran fine with half choke on. If I leaned out the mixture on the high speed needle and not touching the half choke the engine just purred. Then subsequently I removed the half choke and the engine performed fine. However when I throttled back to the start position the engine would slow down and subsequently stop.
What I would like to do is start the engine and be able to push in the choke so that the engine will continue to run without choke then this would allow me to follow the procedure for adjusting first the high speed needle then subsequently the low speed needle then repeating the procedure with the high speed to tune the engine.
Have I missing anything that should be checked or need I adjust the low and high speed needles a bit richer or leaner so that I may carry out the remaining fine adjustment? If so how would I do thst the original manuals do not provide such information
Any help would be appreciated.
