Hello Scott

I agree, the parts list is not so helpful in identifying what
the 0144-01 type actually had. It is clearly not the standard spec
because of its specific mention in the parts list.

Remember, this is a replacement engine, and one designed for
stationary application. I believe it would have had separate
choking - and not from the 'Fast-Slow' rod control.

For mobile lawnmowers, a remote, manual throttle is desirable.
I think you will get auto-choke if you add a cable and control.

I see no point in restoring the original stationary screw-knob control.

Hope this helps.
