dizzy cap and rotor arm were replaced along with with the dizzy. took the throttle body off today to give it a proper clean and also cleaned the inlet manifold.finally got a good healthy idle and ticks over nicely even when cold. :D still running lumpy though and still hits the rev limit at 5000 rpm.

yeah was having a look through. when the new dizzy was fitted, the timing marks were all lined up properly so can only assume that leaves the ecu part of it. its averaging 4.3 mpg :help: and smokes badly due to the rich mixture

could just be 1 tooth out or wrong belt, or somebody has had the cam pulley off and put it on backwards?

:D:D:D so finally after trying to sort the running out for seemingly forever. it is now running perfectly. the timing was out by a mile. the marks all lined up but the engine was nowhere near tdc. we got it on tdc and the cam sprocket was actually out by about 7+ teeth and the crank sprocket was nearly 180 degrees out. got those back in alignment and then re-aligned the dizzy and is running like a new car.
