Re: Johnson HD 25 carb problems

[burnt-clutch]

Here’s the latest – I finally got some fuel proof airplane dope and I sanded the original float down and gave it 4 coats of dope. I re- assembled the carb and tested it in the water barrel. When I press down on the primer gas squirts from the float needle in the top of the Carburetor cap – (not sure if this is normal – I thought that the gas was to pump into the slow speed yoke on the front of the power head). The motor starts, but it will only run fast if I open up the slow speed needle. While I have it running fast, I can adjust the high speed needle in and out (rich and lean) and this has no effect on the engine speed. This leads me to believe that the high speed circuit is still blocked. While I had the carb apart, I ran some light gauge wire through the passages in the carb from the float forward, but I didn’t run any wire through the primer cylinder, because I didn’t think that was part of the high speed circuit. I also checked the passage between the intake manifold and the rest of the carb and I was able to blow air through. Is there a passage that I’m missing that might be keeping the high speed circuit from working? Thanks for all of your replies so far!
