Thread: MIsfiring ,too rich mixture, Need help

Hi Bee utey,
Is there any other reason to secure the outershaft as you have proposed other than to avoid dissrupting the weights when extracting the rotor button. That is, in regard to the actual operation of the distributor?

None at all, just makes life easier when you accidentally yank on the rotor.

Hey guys sorry to but in but i had very similar issues with my d1 i replaced every thing including valves cam lifters coil ign module for bosch leads plugs cap temp sensor for ecu all to no avail replaced dizzy this morning with a known good one and now all my problems have fixed them selfs worth a try as the tune up machine didnt pick it.

So the "Tune-up machine" didnt pick what up ? You say you have done something with the valves (usually means heads off),cam, lifters , coil, ign module,leads,etc etc etc .which didnt fix it , and then you fit a known good Dizzy and all is well .
Whom or what is this tune-up machine so I make sure I never go anywhere near it !!!!

Thanks Nigelbuilding 1984.
I am thinking to go and get the distributor rebuilt. Haven't finally decided on that as yet and haven't had the spare time to do any further work on it.
Will see how things pan out this week.

Have also rechecked compression and found most are about 130 psi . they range from 125-150. with the hand held gauge I assume these figures would rule out any significant valve issue?

yes, although 125 is not too flash but may just be an artifact of the inaccuracy of one of those cheapo gauges, and the difficulty of holding it in the plug hole.

It was one of those sun diagnostic sensor machines at my mates work shop the problem was when vac advance activated it would cut the ignition really wierd new dizzy with working advance and it doesnt do it any more i had stuck valves any way so was an excuse to change cam while was all apart when the ignition was cutting the engine was trying to recover its self therefore why it was running rich.
