Ask The Pros . . .
Thank you for you input Dennis,I'm not sure how to respond to you directly so I hope you see this. I have a 12.5hp cub engine out of a newer model, I checked to see if it would fit, It"s to wide. I have 3 other tractors, 2 with plows and a John Deere to cut the grass. So I quess the 800 will be more for looking at then anything else.
Jeff -Welcome to IHCC.Com. not much activity here in the pulling forum. I have thousands of hours of seat time in 7 & 8 hp Cub Cadets. A 7 hp barely runs a 38 inch mower deck, an 8 hp is only 14% less gutless. 7 & 8 hp Kohlers have at least one too few head bolts, makes it hard to increase compression pressure and keep any kind of reliability or durability. The forecast Conn rod means you have to keep rpm down. So if you can't increase cylinder pressure or rpm, your pretty much stuck with stock horse power.
I have 1975 cub 800 with the 8hp, I want to keep it original but I'd like to squeeze more power out of the 8hp, I'd like to know the most cost effective way to achieve this, any input would be appreciated.

I have a question for you pullers.I am going to use an 18hp cam in a K341 do you run more valve clearance to get it to start?I had one in a 341 years back and was hard to start had to start at idle.Is the duration blowing of the compression.
Started life as a model 71. Tractor classified as a 'Stock Altered'. Single cylinder engine based on the 16hp Kohler (Midwest Super Cub aftermarket block). Dodge Dart rear end set-up with 4-speed. Wish I could take credit for building it. Bought from friend that built it and pulled it several years. Still in excellent shape and competitive.
