Weak joke, you blokes should "workshop" them before you go public.

An 8 x 6 prop on an 1.5cc diesel?

Perhaps why it is difficult to start?


Montgomery Models was the name of a very successful Victorian kit manufacturer in the late 1950's.

It disappeared without trace when the c/l boom fizzled out.

Would any of your mothers or grandmothers be in the picture below?

This is not it , this one took 45 minutes to start and had a bit less power than my No1 Silver Swallow ,

Im starting on Fiery's 2nd silver Swallow ,


that is my third Silver Swallow



it will have a lot less exh timing for the big prop and a lot better piston fit




and the shaft timing that Pe recommends for sport Diesels
