Greetings to all forum members,

I've been fine tuning my 72 m117 engine for some time and due largely to the information obtained through this forum it's running allmost "perfect".
One running characeristic that I currently could use help trouble shooting is a slight but very noticable engine stumble/shutter between approximately 1300 and 1500 rpm.
You can feel the engine's power loss in this rpm range.



Thanks in advance for any and all replys.

Knarf
