Well, after a long break of owning a 6x6, I finally purchased a Max IV yesterday! It has the original 16 hp B&S Vanguard V-twin in it, and I was wondering what kind of mods I can do to that engine. I know the 14hp uses the same block, and removing the little blocks in the exhaust manifold and replacing the carb bumps it to 16 hp, but since I already have the stock 16hp, I want to know if there are any inexpensive mods I can do. If I end up keeping it long-term, I can always upgrade the engine, but at this point I will most likely keep the 16hp.
