I have a 1948 Johnson 5 HP TD 20 That will not idle down without quitting. Also it misses at lower running speed. It seems to run OK at higher speed but it misses but not as much. Any suggestions? It has not been run in quite a few years. I have gone through the carb and cleaned it. The float looks good. What else can I try?
Thanks,
