I'm only too happy to email my thoughts and feedback.
I'm here in Ireland. It shows how global the internet is. People email
from all directions about kart queries.
Ah! I didn't realise there was a centifugal clutch built into the motor!
That makes things nice and easy. Did you procure the engine specially or
was it re-purposed from somewhere else such as a water pump or generator?
I'm sure the students liked the idea of dipping the chassis! I was
wondering if one or two of them had to go painting it manually :-)
The chassis does look very well with the zinc finish. It makes a job of it.
Are the pedals a little on the big side?
That is interesting about the three wheeled suzuki motor bike. Was it a
sort of trike? Did it have a single front wheel to steer with? The
method you have adopted with the single rear drive wheel makes things a
little easier, in that you don't need to have a differential (if you had
of used a solid live rear axle).
