been awhile since I last sold any of the command single stuff on evilbay, been saving alot of that stuff for the pulling guys locally. I built a stock 16hp out of mixed match parts from command singles, no porting, no altering any of the factory parts, just s 6 angle valve job, polish cam & crank, put on a steel adjustable timing flywheel, #26 carb, set governor to 3800rpm running on BP Ultimate fuel & it turned out 23hp & decent on a wide power band. Not too shabby for a little 29 cubic inch single!
Couple others were just straight up timing, factory assemblies w/o any work done & they came out around 19hp each.
Great lil engines to run when you are limited in cubic inch
