Hello from Under Down Under!
Swapped back over to points today, and appart from noticably being harder to start, the miss is still there so have put the ignighter back in so at least it will start a bit easier.... So its looking like a burnt falve or cracked head........
Hmm, that's no good. Is your coil working correctly?
Tap, crackle, pop
Hello from Under Down Under!
if I take one of the plug leads off the dizzy I can hold it 3/4-1 inch away from the dizzy and get a good blue spark... So am assuming coil is throwing plenty of spark and working proper..
Now its starting to miss onn the highway every now and then feels like I've tapped the brakes, or it will cough and carry on then come good again.. I suppose if the damage is done its only going to get worse before i fix it and hopefully get better then....
Have you given it a compression test?
The intermittent miss in my 89 turned out to be the auto choke spring failing and causing it to come on randomly and flooding the engine, causing it to miss.
The missing at idle is constant, my ears prick up and I nearly smile of it goes for 5-10 seconds with out missing, check the auto choke but is fully open when warm.. have also noticed the angine doesnt increase in revs like it used to when I put the air con on, if anything it drops the revs further...
1. its got an auto choke.
2. Timing has been set at 10 BTDC have tried it at 5 and at 15 made no difference.
3. no bubbles in coolant when radator cap off, not loosing any coolant either.
3.5 no using oil appart from the little usual bit of smoke when first started in the morning
4. have check oil filler cpa an clean as
have tried champion and another named brand plug, but dont want to spent a fortune on the iridium plugs yet, as if I have to replace the head its going to break the bank .
5 have replaced plugs, dist cap, leads, even tried going back to points yesterday incase it was the pentrix ignighter, but same miss
6 replaced fuel and air filters after running all the cleaning stuff mentioned below
7 yesterday arvo tacho was jumping all over the place, and car ran real bad, found bolt that holds dizzy in place when adjusting timing had stripped out, so replaced with another bolt and reset timing, tacho behaving now, except for the slight movement when it misses, but the miss is still there.
Thinking it was crap in the carbo or contaminated fuel last week as for the past month had been running cheap fuel from 7/11 in it, ran it near empty on friday, and filled with BP ultimate, and added every fuel cleaner, carby and injector clean and octane booster i could buy from repco and supercheap, over 120 dollars in additatives in total. since then been filling up with either bp ultimate or shell optimax, fuel consumption is now 20.49/100 on that first tank of good stuff, then 18.03/100 on the second and filling up this morning was 17.56/100, have been giving the aircon a bit of a hiding as its been very hot up here in Ipswich and brisbane..
One thing I have noticed as when I turn the aircon on the rev's dont go up like they used to if anthing it drops the revs a little...
Ok, how's the brakes? With the aircon issue it sounds like the vacume (if it has it) may have a hole in the system.
In my Q the vac pump is on the back of the alternator. Not sure f your timing runs off the same vacume or if its independent. Worth a look

Just did the test a few people have said to to, started the car up in the dark and looked for sparks, none to be found or at least seen....
