40:1 is always safe- 50:1 is usual now with our better lubricants.IMO- DON'T WRAP YOUR EXPANSION CHAMBER. Try and find something you can put between the seat and pipe, you don't need anything fancy, you can put a thin sheet of aluminum or steel right in front of the pipe with very close clearance (but not attatched to the pipe) to keep the seats from getting too hot. Wrap causes the pipe to run hotter-also expansion chambers expand and contract.
I like the buggy- looks expensive to build!!!
