Johnson A-45 Mag Plate & Start Up

[David Bartlett]

I had a similar experience with my A-25 recently. My problem was a little piece of dirt in the little tube in the carb. Starts and runs great now.

Thanks Dave,

I’ll pull the carb and check the passages if changing my starting procedure fails to resolve my problem.

Good news!

With a few adjustmets the motor now sounds strong & runs continous until the fuel in the float bowl runs outs. The weather has taken a turn to cold & snow today so I’ll have to wait a few days to put it back in the test tank.

What changed:

1. I changed the fuel mix from 16-1 to 24-1. Prior to the fuel change the motor would run initally after the first few rope pulls when the cylinders & plugs were dry, run for a few seconds and then flood out and not start again. I’ll swith back and try bit richer mixture but it dosen’t seem to like 16/1. (my bottle of 16/1 does look really rich though)  I’ll mix another bottle to verify correctness and try again. 24/1 is probably to lean?
2. Adjusted the needle valve setting to 3/4 turn out from closed position.
3. Set plug gap at .028″ (D9’s) I’ll try the vintage plugs again later.
4. Put some fish paper bottom under the coil/tabs for good measure.

Pleased with the current progress & results.
