Hello all,

 

I have picked up a little Kohler, but i am not sure exactly what it is. The model and serial # plate is missing so i am left guessing exactly what I have. I see things on here that make me think K91, but also things that make me think K90. I hope someone a little more experienced can help me out! Thanks in advance!

   really hard to tell without the ID tags on there, Looks an awfull lot like the kohler k-90 and k-91 I have here. both are almost exactly the same when placed next to each other.  Nice looking little engine, even has the air cleaner on is, good score.  does it run ?

Yep it runs pretty nice. All I did was clean the carb and rusty gas tank and it fired right up.

6 or 7 head bolts? K90 and K91 have 6 head bolts K141,K160,K161 and K181/M8 have 7 head bolts.1 extra bolt between the valves.

I thought the K90 had an experimental ignition system? You'd have to pop the flywheel, but you should be able to tell from that?
(Or am I thinking of some other engine)

Hmm I may have to look into this further.
