Looks pretty moch identical to Predator type,i dont have the measurements to hand though.The crank dimensions look to be the same so fitting the dog wont be a problem.My predator type pull start is 50mm approx between mounting hole centres.

I just heard from Al of BHHanson that the holes of the EZ pull recoil for Zenoah has holes 50mm apart too.
So that would not fit my engine, (56mm apart).
I might be able to use the pawl carrier plate together with my old rope reel though. It would need to have a width smaller than 56mm, and the pawl positions would need to match the 2 "teeth" of my reel.

assuming the new recoil starter will blot to your crankshaft, then all you need to do is make an adapter plate since you are going from bigger to smaller (other way around might be a problem).

you machine a 56x56 piece of aluminum (1/8"?), cut a hole, cut 4 holes 50mm apart and thread...bolt and enjoy.

basically like a carburator restrictor plate

OR.....use the old school method pf putting a starter cup in place of the pawl plate and winding loose rope around it to start it.. kinda like the older lawnmower engines.. just a thought..until you get it fixed properly that is

Smile! people will wonder what you're up to!!

Time to wait
Thanks everyone.

I found what looked liked the exact replacement pawl after looking thru the parts manuals at tanakapowerequipment.com
I've ordered 3 pieces from "M & D Lawn Mower Parts", US$4.14 per piece! (just the little black plastic pawl.)

When it arrives in 2 weeks, I will probably shim up the pawl-carrier-plate with washers so that the pawl engages the reel better.

EDIT:
I received the pawls from M&D Lawn Mower Parts.
They are now made of white plastic, but shape seems to be perfect match.
I added a few washers to standoff the pawl-carrier plate so that it sits nearer to the rope reel, and so the pawl engages the nubs on the reel better.
Pull starter works well now.
Starting seems to be easier than before too.
