Right. Went down the to truck today. Spent 2 mins installing new parts. Helped some but not all. Took it for a test drive. It ran decently, but not amazing and still had that damn rough idle. Stopped, gassed up, adjusted things based on google search parameters and test drove again. Starting to think I've got a stuck valve or even a burnt one or many. Drove to the parts shop to buy a plug socket and pulled them on the footpath. Dirty, but not filthy. Bought eight new plugs and threw them in. Also retarded my timing a little as the engine as pinging. Hit the key and it fired right up. I didn't notice if it idled well as I was too busy pouring vaporised carby cleaner down those barrels in the hopes of de-gumming/loosing any s***e that was present. 4500rpm outside a parts shop with shorty headers sure is fun. The parts shop kid was a mechanic, he said he saw a heap of s***e come out the exhaust. But he did get excited over a snail that cruised past, so. Brought the idle speed back down [used to compensate for the wavering idle, then called it good. It runs like a champ now. The new coil/cap/rotor/plugs sure did wake it up a notch. The coil/cap and rotor were the only things I didn't do to that motor, and as they were OEM there's a good chance they had been plugging away since 1981. Anyway, sorted for now.
Part of me thinks that the degrading dizzy/rotor/coil gave me a weak spark, which in turn neglected to burn all the fuel, which in turn fouled the plugs, which in turn gave a weaker spark, which in turn neglected to burn all the fuel.. etc.. until it gave up on me.
If it runs for more than 2000km on those plugs, I'll go ahead and assume that's the reason. If not, back to google..
