Between deer hunting:I pulled the smoking, choking model 73 out of the barn and brought it in the garage for a look at the engine top end.
Found out a couple things.
1. Pulled the head off and found lots of slop in the piston side to side. Valves had some minor movement too. Lots of carbon. Looks like a rebuild of this engine next year.
2. Wiped off the dirty oily grease from the rear cover and found the factory sticker proclaiming that this is a 8 HP. Since I haven't gotten into the hp info for different models, I guess this makes sense? model 73= 8 HP?

Anyway that was not of great concern to me I like the way the other 8 Hp runs on the model 83, ( I think its a 8 HP?)
Buttoned this model 73 back up and while the son Eric was here he took it for a smokey "Spin and Grin". I think he would like to have it at his place to keep the 106 company!
Eric got a nice 8 point today (last day of archery season for PA). So I helped him process that and get it in the fridge.
I did briefly look at the plow and tiller I have. I need to take some pictures and post them So you folks can get me started on new projects.
Regards,
Chris
