Re: 1962 18hp Johnson Only Runs With Choke.

Here’s a little background on the engine. It sat in storage for maybe 30 years. I bought it from the son-in-law after the owner passed away. The motor was winterized before going into storage. The carb had a little hard varnish on the bottom of the bowl and the needle and seat were stuck. Everything else looked surprisingly clean. I pulled the soft plug and it was clean inside. I sprayed carb cleaner throughout all the passages that I could find. Adjusting the low speed needle while running on the choke had an effect on how the engine ran. Low speed needle is set to 1.5 turns out. High speed is set to 3/4 out. I thought about the seals because it sat so long, but I guess I should pull the carb and see if I missed something before diving in further.
