Thanks. 1st glance looked like a convertor housing.. 'Got a couple of new centrifical friction clutch's too but after freshening the 172cc Original Techumseh, it has that much compression after a Flathead V8 style Port n Relieve with Milled head its hard to Pull start, so I by chance happened upon the C90 Honda mill, with its lighting coil, ease of spears & matching chain to the drive sprocket (+ its gear selection) ...
Still interested in the diffence a t/convertor CV makes over the std ave 6:1 autoclutch gearing.
Std T Roadster ? They'd be worth a decent coin these days ! ( my T Bucket pickup was built off old "Fad T" Plans : suicide Front axle, Happy Days 'Ralph the Mouth" style Lakes headers etc. Still kicking myself ( but lost storage=unwanted Sale)
Cheers T.
