Hello folks,
I got my hands on a relatively "new" 1969 4hp lightwin model 4906. The factory paint was never broken from where the original plugs enter the head! It was used at a local high school for demonstration purposes only. It has never seen the lake! I am in the process of cleaning/possibly rebuilding the carb. I had some troubles initially getting it to start. Eventually it fired up. I have a question about the upper valve ("speed") setting and the lower valve (rich/lean) setting for start-up and normal operation. Also, what is the proper fuel mixture? I have read many different threads...some say 50:1 others say 40:1.
I wish everyone could see this thing...I pulled the cover off of it, and it is in pristine condition, I could barely believe it. What a find! Thanks for any and all help.
