My Dellow has a 100e with Aquaplane head and Shorrock blower and i am plagued by a misfire under load when the engine is hot. failed to get off the line at the MG Spring trial.
Engine strts cold Ok and accelerated with no problem until hot then misfires when you really need it.
Have changed coil, condenser dist cap, plugs -tried NGK B6ES and B8ES .
Sometimes engine cuts out when giving slight acceleration from rest then will not restart until you let it cool down for 15 mins. Any ideas before the Lands End?
