Excellent site, this is fantastic for searching for info! Kudos to you all! Like you've all seen before, I rescued a 1955 Johnson JW-11 Seahorse 3hp, in good shape, had been sitting for 10+ years without running, gas in it. Totally disassembled carb and cleaned out every nook and cranny. Fuel tank spotless, as is fuel line and shutoff valve. Gaskets looked good actually, didn't put in a carb kit (yet). Lower unit oil looked good, she cranked up on pull 3! BUT, now will ONLY run with full choke. Fuel filler cap vent is open, so don't think that's the culprit. When running with full choke, and then when it's closed/off, the motor will surge and then die. Any ideas on what could be issue, what I missed, etc??? Any and all info GREATLY appreciated! Thanks!
