Zach Kerber machine sells a nice reground cam for $135. If you deck the block and take .045 or .050 off the head and put a nice three angle valve job on the valves. 20+ HP should easily be had out of a k341.

That's what I was thinking. Don't forget you can bump up the RPM to 3800 on it along with advance the timing a few degrees. All that will surprise you on how much power you will have.

I wasn't knocking on you or anything. I'm all for re-powers. It just doesn't make sense to me to use that particular motor. :beerchug:

actually with a bit of work you can get 20 out of a K321.

how much should one deck the block in order to get 20hp? doing a three angle for the valves I always do on my personal engines as well as polishing of the intake. does either Lakota's 117 or Zach Kerber machine's cam grind 1 or 2 have compression release for easier starting? also which cam is better in anyone's opinion? I am not looking to spin the engine faster the 3500 cause I simply don't usually need it that high. I mow with a mildly built k301 with a 48" deck and it doesn't have any problems. this 1650 will see tilling duty the most do im looking to build an engine that can handle that without any problems and sounds good while doing it. my theory is if I am in there to rebuild the engine since that is the route that I am going I might as well get HP that is there to be had.

J-mech; yeah I did not take it that way, just looking for opinions, I knew about the valve seat problem but wanted to try something different. I have always thought OHV engines were cool and why not use one in an old cub?

Yes either Kerber or Lakota cam will have a compression release. You send them your cam and they regrind it. If you are in a hurry I would recommend Kerber. Lakota has to send it out to be ground.

As for decking the block I always measure it. I have it decked so the piston is flush with the top of the block. That measurement is typically between .020 and .030. So before you disassemble the engine get your measurement.

Just wondering if the CH16 out of a 2166 would play?

The frame is so tall, IDK if it would fit.....

I have two QL's sitting here with no motor and a CH18 on a base. I could look and see how things line up. :bigthink:

Crank height is an issue. But could be solid mounted to help that. Then the trans could potentially be raised up to make up the difference.

But I am not sure if there would be any issues with width.

How about a cv style shaft and Sams adaptors for height misalignment? I'm guessing width would be an issue for side panels, at least it is for vanguard vtwins. I assume ch is comparable width? Be cool if it would fit, I see plenty of ch 16 and 18 donors on clist cheap.

This is the link to the service manual for the CH16, it has the dimensions of the engine.

Not sure but I think you could use a motor plate like the later tractors did to mount the engine.
