hiya,
Dennis I found the 220 Roller engine as fitted to the Big J a reliable enough engine
never having any trouble with them and they would “out tub” the Gardner 240 all
day long (and I’m a Percy fan) but me not wearing the guvnors cap I wasn’t caring
about MPG as yourself would take into consideration, I didn’t find them any more
noisy than the ■■■■■■■ engined jobbies we had at the same time, Oh’ yes and if
I could have swapped that bloody 80 thing for a Big J I would in the blink of an eye.
thanks harry, long retired.
