Thank you Paul_C cheers2

Deejay so I take it the fan was an improvision?
The whole set up looked like was knocked up in someones back yard.

Unfortunatly the wooden block has to go, Termites!!!
when I stripped the engine it had wasps living in the muffler and ports, the little buggers didnt wipe there feet
and filled it full of mud and sand.
Will post pic's later.
Regards to all
