I've got an old, pre-70's dilapidated TroyBilt I'm gearing up to rebuild, largely for my own education on mechanics. Linkages are broken, fuel tank is missing, lots of work to be done so I figured why not rebuild it to run on biofuel. Not sure how well I'm navigating the site but I haven't found much on converting engines, biofuels, etc. to go off of.
I'm posting in hopes of receiving any information sources out there people would recommend. If anyone has strong opinions about battery power vs biofuel, vegetable oil vs processed alcohol, etc. as well I'd love to hear it. As I make headway with this project I'll try to post progress I've made, or pitfalls I've found.
