Hi,
I've been trying to diagnose whats causing my A series engine to run abnormally today. Drove it yesterday and it ran lovely on a long trip, topped up my oil (does drink a bit with 50 years of use ). Came to start it up today and needed an usual level of choke and seemed a little rough. Turned it off and cleaned dizzy and rotor arm (thought I might be running on three) and all seemed well until driving home sat at the lights the revs dropped and i had to use a LOT of choke to keep it going and ended up free wheeling with the engine off until I found a petrol station to pull into. Seemed fine after cooling down and restarting the engine.
I'm not sure it's temp related (happened when cold this morning and hot this afternoon). But when it shows the symptoms the whole engine feels rough and unhappy to rev, needs choke to keep it going and produces less power than normal.
I've got a few ideas I'm going to check early tomorrow morning but anyone got any suggestions for me?
(I'm optimistic it's nothing to do with the head/compression )
