Need Help With My 4kc

and maybe chase a leaking manifold gasket... It sounds a tad fluffy, not sharp on some engine beats.

 

We get the random misfire occasionally, not as often as your motor, and I put it down to a worn dizzy shaft or something similar, when the gears flip from tension to compression, or from one side of the gear to the other and causes a change in timing. Once you accelerate everything lines up and works hard, so it only occurs under no-load at idle.

 

Old Fella's idea with the cap stubs can be worked on too, you can scrape any oxide off and bend the stubs towards the rotor with a flatblade a mm or so, if they are soft. (aluminium)

G`day mate, I agree with Taz_rx in that you should check for spark leakage between leads, coil, dizzy. Wait until it is dark (really dark) lift the bonnet and start it up. You may have to look hard but it sure sounds like spark leakage to me. I also notice that plug leads 1 and 2 are touching. Try separating them with one of the plastic tube holders from your polution pipes. It might just work. While you`re in there, check that all of the polution pipes are connected properly. Only takes 5 minutes and that will eliminate another possibillity. Also check that the air gap between the rotor button and the dizzy cap is not too big. When the metal bits inside the cap get worn the gap increases and can cause missing like that.

Good luck.

ok thanks guys ill try that too :)get them on friday hopefully
