This engine has been part-built from a set of Stuart-machined castings. It has been well-made so far, turns over very freely and is complete with flywheel, crankshaft assembly, cylinder/valve chest assembly, beam and base. It requires the Watts link making complete with spindles. The eccentric strap has been made. We have run this engine using "donor" parts from another beam and it runs very nicely. This engine can be supplied as is to complete, or we are happy to quote to complete it.
