Hi. Has anyone ever tried to fit a different carb to a 13, I was thinking of making a manifold and fitting a single large bore carb to mine as I have a naff set of carbs,
Number 4 cylinder runs rich all the time despite doing all the cleaning tips elsewhere on this site.engine is ok with good compression all round. Could it be the coasting enriching device be blocked but wouldn't that make both plugs black on that carb?
I'm not bothered about a power loss just want the smoothness back ,had enough of the stuttering on take off.
Cheers. Mark
