G'day Maurice Paul and Jack
The 'A' designates an aluminium head.
So Max, do you think this engine is, in fact, a Hurricane Model 125A?
That seems to be the engine I see.
Yes Jack the motor looks like the 125A ,I was going by the info on Vintage mowers but it looks
like where it lists the AMPLION MOWERS WITH THE 125 AND 160 CC ENGINES ,the
160 should be 185 total cubic capacity or 150 for total cubic capacity unless marketing called
the 153 (154) swept volume a 160cc ,I had a 490cc bike that was marketed as a 500 cc.
The thing is the bigger bore motor is only 6.35 mm bigger in the bore diameter so I would
say it may be difficult to tell the bore size from an image of the Hurricane motor.
I'm not sure how you can tell the bigger Hurricane motor from an image unless the muffler
mounting flange is larger with the 153cc (154cc) swept Volume.
Vintage Mowers does list the COLLECT-O-MATIC as having the 185 cc motor as an option.
Cheers
Max.
