OS .91 DF Needle Valve (9B Carb) Compatibility
 

Hey, I would like to know if the needle valve from an OS .61 will work effectively in my OS .91 DF Engine.. I just purchased the DF engine (second hand) and it did not come with the needle valve in the carb.. I need to get this engine installed and running by Friday, however nobody can have one shipped here in time so I'm grasping :D

Any help would be appreciated..

Thanks.

If the needle is the type that will screw into the needle holder, then it will work. It may be too sensitive or not particularly so. It may even have a slim point that won't regulate particularly well...can't tell until you try.
