Jacobsen Commercial 20 Carb Problem
I have a late 60s/early 70s vintage Commercial 20 with a 501 engine that I got from my dad. He got tired of replacing cheap mowers every few years and bought a Jake from a local golf course/estate lawn equipment supplier. I have had it for about 25 years, but for some reason the escapes me now I stopped using it about 10 or 15 years ago. I recently came to my senses and decided to start using it again. I was not getting any spark so I pulled the flywheel and cleaned the points; now I have spark, but gas is running out of the carb throat (it's a Walbro 195). I'm thinking I have a stuck or leaking float, or a bad needle valve and seat. Is there any hope of finding replacements for these parts?
Any insight/advice anyone can offer would be greatly appreciated.
