Re: Here I go again,Briggs build
Was never much of a Predy fan though I have used em with ok results. Have done several builds with the Lifan 2.5hp flat head and really liked them a lot. Guess its time to use the little Briggs. Its fairly old maybe a 67 as I remember. Been packed away along time. Hopefully will be able to use the updraft carb. I do have a carb like the one you used from when I put a Honda clone ATV engine in a bike. I can use if I need to. Will probably ditch the pedals and use the bottom bracket as the jack shaft.
Your build is the inspiration I needed for another 4stroker.
