No fuel to Cylinders

Sorry for the novel, but I'd like to give a little history, it may help.

1963 Johnson RKL-25D Electramatic 40 HP. I bought this engine with an old boat and it was seized from non use and had a squirell living it for some time (I found acorns in the mid shaft) as well as bees. Everything was in such good cosmetic condition that I assume it must have been "barn fresh" Right now I'm running my '78 Johnson 55hp on the boat, which runs well but obviously isn't correct vintage.

I freed the motor and bought the obvious items, carb kit (I also bought a used carb in good condition because the carb was so bad), fuel pump kit and impeller. All have been installed. Carb and fuel pump were soaked overnight and blown with compressed air, replaced float, seat & needle, repacked and cleaned low speed needle, removed and cleaned fixed high speed jet. So where should I begin looking if the plugs are dry after crankling? I'm thinking maybe I should remove the reed assembly to see that nothing is stuck there.

There is also no spark and I could have sworn that it had spark when I initially assessed the motor, but I'll deal with that after the carb issues. I bought the old johnson manual on CD that covers 1922 - 1964 Johnson motors. It has good diagrams and good model specifics, but only general troubleshooting.

Thanks for any assistance

On more item to note. Fuel is geting to the float bowl.

Does the motor have good compression? It will not draw fuel if it's too low. Choke working? It wouldn't hurt to see if something is in the reed area....

I haven't checked with a guage, but judging by how hard it is to pull I thnk it's OK. It has a hot water choke that's mostly closed at rest, but I've tried full choke as well. I also disconnected the pull start safety and tried pulling at WOT to see if the low speed jet was clogged and still nothing.

Thanks for the replies. I'll pull the reed cage to see what they look like.

Re: No fuel to Cylinders

When I pulled the reed cage, there was something that looked like sawdust inside. I vacuumed it out and cleaned all surfaces. The reeds wouldn't sit flat against the plate until I cleaned the plate and reeds. There wasn't much gap and it would close if I pushed it against the plate lightly. Would that littlt bit cause this problem? They have to open to allow the fuel through anyway right?

Check your compression. If compression is low or none it wont pull fuel into cylinders. Maybe fuel primer bulb not doing its job. What kind of material was in the reeds? Was it foam particles from cowel cover? Good Luck!
