Can anyone answer me on this one please? I have the old style block with the 1-1/8" exhaust valve. I was wondering if it was possible to cut out the old seat and insert the new 1-3/8" one and put in the new valve?

I looked at that site for about an hour last night, looking to see if it was offered. I must have been tired, because I just could not find it. I did find it now, thank you for making me go back and take another look.

SO,,, that brings up a question..??? How can I re-size my throttle shaft openning... is there a sleeve.?? My throttle shaft warbles at the intake and causes the throttle shaft to bounce around.......??
There are bronze bushings that people use on the throttle shaft. Drill out the body of the carb and press in the insert. I will see if I can find it.

Another question, if I make this into a twin by mating both blocks and machining both cranks to mate up, is it possible for the original carb to feed both cylinders?

I don't know if I will have the problem with running them the same. That is why I want to run it off one carb. I literally am going to bore the front crank out and then I am gonna to insert the PTO end of the back engine in the front crank and set screw it in. I am gonna keep both cams separate, but they should rotate together based on the gearing. I think pullers use one carb spinning well over 4000 RPM which would be like feeding this twin off one carb. I have thought about adding a fuel pump too.

Isn't there a two cyl. engine available that would save you having to reinvent this whole thing? I've seen a puller w/ a Suzuki Hayabusa engine that was killer.
I have been looking and not having that much luck. I wish I could find one. Does anyone have any suggestions? I would really like it to be an inline twin and around 18 hp to 30 hp and not a budget killer. Would like to keep it at 3600 RPM, too. On a side note, I do have a Wisconsin THD that is sitting around that could go in there, but it is in pretty sad shape.

I would go with the THD. The money you spend on the homebuilt would rebuild the Wisc. I'm not trying to be a kill joy, but I'm afraid after you get the dual Kohler together, you will spend a lot of time trying to get it to run right. Now, if you were to belt two engines inline, that might be doable.
