Re: back in the day...
Welcome to the forum. You might try taking a look through our DIY, non kit section for some input and ideas. There're guys here using Briggs & Strattons, (or is that Pratt & Whitney?), engines and power plants from everything from chain saws to washing machines. Keep us posted on your first build. Have fun, ride safe.
