Sup y'all,
So, my wee 4wd Lancer hasn't given me any grief at all in the time I've owned it up until now. It's always started first pop no worries but just this week when it's cold it's just randomly not starting. Turns over sweet but doesn't even cough or try to start there's just nothing there.
Have checked for spark and it has a nice blue spark, fuel getting to carb no worries and carb squirts fuel as needed. Checked coil and lead resistance and they're all within spec. Replaced dizzy cap and rotor cause they were a bit ugly this avo and no better.
It seems if you leave it a while and try again a couple hours later randomly it coughs and splutters and comes to life, when it's alive it runs perfectly and drives no problem. Bit of black smoke under heavy load.
I'm kinda stumped, the only sorta thing I can think of is a carby issue? It's a 4g37 by the way, any ideas anyone?
