New 104
 

I have this 104 and it has low or no compression. Mean while my 127 is in parts, many parts. The engine runs fine off the 127. Will the 12hp bolt right up? I have plenty of toys to cut grass with, just figure the cub is more indestructible for my teenage sun. I'll post more of the 127 later.

I'm going to say yes, yes it will. They're both narrow frames and both K series engines so have at it.

Had same problem with my. 105 had no compression, did a quick valve job cleaned all the carbon and it has tons of compression and runs great.

Throw that 12 horse in there and don't look back. Should bolt right in. Good luck!

Thanks to all. I'll try to swap 'em out tomorrow. The PTO clutch probably needs a lot of a attention also and it has no fire. It will aid me in taking my time on the 127. I think it may be the valves I can feel air moving but not pushing and pulling, so something is happening in there.

That's exactly how my 105 sounded. Cleaned the carbon build up off the valves and runs great now.

It will indeed fit.. by the by where in SC are you?

Just south of Charleston. I wish there more Cubs around here, I paid 200 for this one on Johns Island.

The 12hp is in. The PTO belt that came with it is too short. When the belt is installed I think it'll cut an acre. The deck number is 421 U 1113.
