Well just reporting back. Not had the really hot weather again to fully test the modifications. The fuel is now not boiling.
I drove today 5 miles to Barry Mulroy’s house ,I considered the adaptions to be doing their job. Barry however was concerned about the temperature of the inlet manifold and subsequently the top of the carb. He suggested making a heat barrier between the manifold and the carb using a Bakelite type material.
Having returned home I made the said spacer, 10mm thick and fitted it. I took the car for a run and the difference In temperature between manifold and carb is quite noticeable.
It was mentioned in an earlier post that the longer the inlet tube the more toque obtained, could 10mm about 10% make much difference, because it feels like it does.
I’ll take this opportunity to thank the input received even if some of it was tongue in cheek.??

I am always interested in any information about Rosengart details or current owners.
