Greetings Brains Trust
Have a question regarding the above mentioned machine that is equipped with a 5 speed manual.
It was hesitating under load (2, 3 and 4th gears), ok in 1st and top.
Changed plugs, distributor cap, checked plug lead resistance (all under 20 K ohms/metre) as well as obligatory fluid change with filters, carb cleaner down carby and new fuel filter. Adjusted timing, and changed coil (outside of resistance specs). So far, the car has improved dramatically, yet when it gets upto operating temp begins to hesitate and miss in the 3000-4500 range. The tacho is jumping about 200-700 rpm jumps and I am at a loss to discover why
What is going on?
Also, I changed the dizzy cap as the plug poles showed an odd corrosion on them. This corrosion has returned in under 300 kays of driving.
The mech advance and vac advance are working on the dizzy (confirmed with timing light).
Are the electronic ignition systems on these things responsible for this erratic tacho behaviour as well as the poor acceleration and missing in the
3000-4500 rpm range?How can I get the tach to behave?
Very interested in any ideas that are out there!
Cheers
