I looked at engine ..item #160058487646... it lools to be a Mac Mb290. This same exact engine is also sold under Yardman. I could never get parts for My Mb290. But I think the Yadman web site you can get parts. Not sure. They seem to be a nice engie. Flipflop...I do not hammer on my engines. I have taken many flywheels off...ect and not had to hammer on any. I checked the end-play on the one I had BEFORE I took anything apart on it. Capt,n
