My grandfather gave me a 1984 2HP Evinrude (E2RCRS). It has a built in fuel tank with a gravity fed fuel system. Single cylinder.
As a learning project I bought the following parts and installed them:
Head gasket
Carb kit including float and needle
Impeller
Spark plug (set to .03 JC6 I believe)
Plug wire and boot
Fuel hose
Fuel valve with new screen
After that it started but ran kind of rough. I could play with the carb needles to smooth it out a bit, but it never ran well and wouldn't rev up to WOT.
So I took the carb down again and soaked it for a few days and put in a new kit. I used a thin wire to clean out all the holes and blew compressed air through the whole thing. Its very very clean.
Started it up again and it ran better, but still had issues. I played with the needles to get it to run WOT which it did quite smoothly for about 10 seconds then stalled out and wouldn't start again.
So I did the carb AGAIN, and put in a new ignition coil, new point (set to .02), new condenser, and a new complete plug wire assembly.
Now it won't start at all. I can pull on it all day long and it won't even try to start.
I have very strong spark and decent compression, so I assume its a fuel issue.
If I remove the lower (high speed) needle gas pours out so I know its at least getting to the lower part of the carb.
I tried laying the motor down and pouring some fuel mix directly into the carb. When I did that I at least got some exhaust to puff out the motor for a few pulls, but it didn't start .... or even hint at starting.
Because I have good spark, can I assume my entire ignition system is working properly? Could I have good spark and still have a problem with the condenser, coil, point (which are all new)?
This sure feels like a fuel issue ... like the gas isn't getting into the upper part of the carb .... could it be a float/needle issue? I admit I don't fully understand how everything works inside the carb.
