Does any one have details of the CH/HT engines such as engineering drawings and specs for the motors?

Im trying to get info together for someone who wants to get some better quality engines built in India based on the HT's

What I hope is the engine will be higher compression and built with better metals and tolerances. It is likely to be more expensive - but I think the difference will be worth it.

HI Jemma,

I like your idea....You are the (wo)MAN! ;-)

I have searched near and far , high and low but have not been able to find any (I wanted technical info to help build tuned pipes originally)...

Unless somebody else can turn up something, I wonder if it would be worth shipping an entire engine to a perspective manufacturer for them to dissect and take measurements from??...of course the danger there is they get a defective engine and then make a series of defective engines from their "blueprint".... Hmmmm....

Great idea ..I would love to see a high quality high performance "Happy Time" engine!
