Guys
Many thanks for your responses to my dilemma, i will contact Keith on the above number to see if maybe able to help.
The motor itself is connected directly to the shaft then straight to the chain linkage. So is that correct that i only need the keep the RPM to the same as before?
Many thanks once again i will keep you up to date on how i go.
Also i have looked on ebay to no avail but i'll keep looking
