61 Crankcase size

[RC_Flyer]

I’m trying to replace some 61 two stroke engines that are 39 MM at the crankcase mounting area and a little under 100 MM in length. I cannot find these specs on your for website for any of the 61s. Could you please post the names of the engines you sell that are in the 39 MM to 40 MM or 41 MM. I know the K&B twist ABC fits, but what about the HP and RJL and others.

I went with two RJL K.61s.
