Hey all
I posted about this months ago with no luck, and have just lived with the problem up to now. But it's been getting worse recently, and I'm stumped.
March 1.3. Starts and runs fine. After about 3 miles, while she is neither warm (thermostat open) nor completely cold, she starts to hesitate badly if I accelerate. Cough, splutter. When not in gear she will stall unless I am REALLY careful and light on the throttle. (Coast up to the junction, very gently rev her up, slip clutch to go!) If she does stall, I either have to wait 1/2 hour for her to cool down, or turn her over on the starter for about 10 minutes solid with full throttle. Not good. Bye bye battery. BUT, if I'm on a hill she will bump every time, no problem. One she is fully warm she is perfect again. But then leave her for 30 mins and she won't start at all...
I still suspect the choke, not least because when she misbehaves like this tickover increases to about 1400 rpm. Can anyone tell me anything about the choke system? Can I disable it at all? It looks as though some coolant passes through the TB, is there temp sender in there somewhere? Is the choke mechanically operated by the coolant temp? Help!
I don't want to start replacing TB's or other parts, as she is a rusty budget banger. If I can't fix this very cheaply it'll mean her death soon... :-(
P.S. Vastly improved this over the winter by putting cardboard in front of the radiator. Engine and heater warmed up quicker, problem minimised, and noticably better fuel consumption on shorter trips. No good at this time of year though, as she runs hot and fan works overtime.
