Hi
I am having difficulty in getting the car to start and am wondering if anybody has an ideas: -
I had removed the head to re-set the tappet clearances, fitted new exhaust valves, lapped these in, cleaned up the inlets and generally cleaned up the head & piston crowns.
All re-assembled and great care was taken to ensure that the iginition timing was correctly set up.
When all was re-assembled the car would not start!
Engine turns over, each spark plug produces a spark, fuel is getting through to the carb (fresh fuel) but the engine will not fire.
As part of the engine overhaul the following parts were renewed as a matter of course: spark plugs, distributor cap, rotor arm, coil, HT leads, starter solenoid and Aldon Automative electronic ignition (for postive earth). Before I installed these parts I tried to start the car with the original components - which were fine before I took the engine apart.
So, when the car did not start, I checked all the electrical connections and voltage readings were all ok to the control box, fuses, starter solenoid, starter & from ignition switch, ALL seemed OK... Battery is about 2 years old and is fully charged.
I checked the conpressions, these were all fairly even at around 150 psi, which compared to the workshop manual figure of 160 psi, which I do not think is not too bad for a 40 year old engine.
I have not been able to check the strength of the spark, but these are all consistent and I am not sure what else I could do if these was weak.
Fuel is fresh - old fuel was drained off and replenished just to ensure that this had not gone stale.
The last thing I have done is to re-set the carb on its initial setting, which is not far from where it started.
I do not know what else I can do, everything seems to be doing what it should.
Finally, yesterday, I re-checked the timing, with the engine locked in its EP position with the number 1 exhaust valve fully open, all lined up perfectly (I don't think you can get this wrong). I removed the distributor, checked that this was all correct, not 180 degree out and all seems to be ok. Timing is set at 4 degrees BTDC. Have tried at 6 & at TDC, also to deliberately put the ignition 180 degree out, but nothing, not even a hint of ignition.
Between each time of trying, the plugs have been dried (allowed to cook in the sun) & I have swopped these over, I have substituted the coil, the rotor arm, the distributor cap & HT lead, & reverted to a points set up just in case the old components and the replacements have been defective, but to no avail.
If you are still with me (& I hope you are) I am now at a loss of what to do or check next - any ideas anyone?
I look forward to your posts.
Many thanks
Gary
