Does the drive plate not go on far enough?
You can get steel ones if you don't use an electric starter.

EDIT: I wrote that before I saw Dan's post.

A steel thrust washer that will not extend past the crankcase neck OD. Not a drive plate. Smile

Any particular reason for a steel One Matt?

The phenolics that Bernie sells are just a touch bigger than the crankcase neck OD's,,but you can carefully trim them down and get it right to the OD.

Just wondering why you need a thrust washer.

Is the phenolic washer preferred, for starter users?
Yes guilty as charged, occasional starter user. John

Yes, I don't think it goes on far enough. Plus I think the original KBs had them. Not sure though.

Add a washer or two on top of the prop you're using to pull the plate on. It may go on further.

That doesn't necessarily mean it needs one.

I don't want to strip the threads though.

Your screw may have hit bottom before the drive plate was fully seated. If there is more room under where it already is, then you won't have to force it. A couple of washers will let you get it on the last bit. If it doesn't move any more with reasonable force, then you really do need a thrust washer.

I was using one of these things - http://coxengines.ca/assembly-tool-for-cox-.049-engines.html

I guess I could use a standard screw though.
