I'm in the process of re-assembling a K&B .61 ringed r/c engine I tore down about 10 years ago to replace the bearings. It was purchased new around 1980. It has the block style K&B carb.
As best as I can recall, this engine had a machined aluminum "spacer" on top of the cylinder between the crankcase and head. This "spacer" has unfortunately turned up missing due to the many years of storage/moving.
I cannot find _any_ references to this part on the web or Mecoa.com. The 6550 parts diagram makes no mention of it.
Do any of you know where I could find a replacement, or at least a blueprint of the part so I could machine one? Is the current model head made to eliminate this "spacer?"
Thanks for any help,
Kal
