I have to hand it to Woody Bartelt. I can only imagine how much work, engineering, and expense must go into some of those replacement parts. Just a timer assembly must start with a lost-wax casting, followed by machining. And any internal parts must be fabricated precisely, and usually heat treated so they will fit.
He charged me $55 for a complete timer for the Orwick, so I can convert my Orwick 29 glo to spark ignition. The replacement parts are well made, and fit perfectly.
