Hi,
I noticed an old post on your previous web site and a member said they have a manual in pdf of The Bux 120 2s engine.
I have just purchaed a Shay Rotogardener with the Bux engine and as it hasn’t been run for quite a while I may have to strip it down.
Cheers
Guy
Looking at old site I think I may have the documents referred to, owners manual and parts chart. The files are to large to upload to this website though, if you send me a private message with your e mail address I will send you copies.
