Ive got a 18rc in my 1st gen hilux, took it out today, and was going ok till it just stopped, checked spark plugs, they were abit caked with crap so replaced them, had fuel to carby, checked points under dizzy cap, cleaned etc, and still no good, untill i thought id out a test light to the resistor as i was cranking, postive side lite up no drama and as soon as i touched neg side, she started, is it a bad coil? Bad resistor? Also as i was trying to start it i check the lead out of the coil and spark was or looked weak. Cheers in advance.
