That D7 is absolutely beautiful , a contractor in our village ran a fleet of Cats , I spent endless hours just watching him grubbing out trees in the 1960s , no track machine comes even close to a purring Cat.
Are you certain it had a recoil stater , I seem to vaguely recall the earlier ones were conventional rope start , but I do stand to be corrected.
Some close up pics of the engine may help us.
Remember the first MK15s fitted to the Howard Bantam had the V508C carb fitted(later replaced by the S12) , so the carb you have is the correct type and fitment. Fortunately it is a very common carb , so spares are readily available.
Well done Geoff , I really enjoyed the programme , it illustrated the truly monumental effort of farming in the day , unlike todays farmers who moan and groan about anything and everything.
With all due respect , if a company can’t make a relatively straightforward cutting cylinder , something is seriously wrong with them.
It would be a doddle for any reputable engineer.
Charlie , it’s a Hayter , but don’t recall the model name , a neighboring grower to my Father had one which we used to borrow , I spent many hours using it.
