Hi Michael no I'm running carbon core leads, I think I'm pretty much resigned to valve damage having occurred

Cheers guys yes crab type distributor so timing is pretty much a preset, I've verified the vacuum brake is working , so I'm guessing valves are the issue . many thanks for your help guys

Hi Phil I've hooked up a vacuum gauge and I have a vacuum of 18" but the needle is not steady it fluctuates between about 14"- 19"

Hi Kevin yes checked and rechecked mate, rapidly getting to the decision I have vale trouble I know they all open and close as I turned the engine over with the manifold off and could see them all open / close but guessing a burnt valve

Many thanks for the reply, I have checked all leads for a good strong spark and all look good, I've put a pressure gauge on the pump ) and I have a regulator in the fuel system) and its delivering a steady 2 1/2 psi so all good there. Altering the mixture screws does alter the running of the...

OK guys distributor cap changed, rotor arm changed, coil changed, air filters changed, ht leads changed. Distributor cleaned and overhauled, timing checked, confirmed no vacuum leaks. Car started immediately and still runs badly with an uneven idle, and backfiring through exhaust when revved...

Hi guys I've dug a little deeper with the coupe ignition and I concur I think ( hope) it is an ignition problem. I've come to this conclusion partly from the replies from you guys but also because the car is running a pertronix ignition unit and 1) the spark plug leads are solid copper 2) the...

OK guys here's the latest, I refitted the original manifold with a new gasket and fitted a new not rebuilt carb , hooked it all up and ..........its running rougher than ever refuses to tick over below 550 rpm bangs and pops through the exhaust as soon as you touch the throttle and souñds very...

Hi the car isn't running points its running pertronix ignition I've been through the plug leads and checked them all for a spark, the vacuum adjustment was loose so not too sure where to set that.

Original manifold refitted with a new gasket and a new standard carb ordered, due to not being able to run the car at the moment I performed a cold compression test 6 cylinders showed 105 psi 1 cylinder showed 115 psi and 1 showed 120 psi. Hopefully this is ok, the new carb should be here...

Hi guys thanks for your help and suggestion's, if I remove the restrictive air filters I can get the car to idle fairly smoothly albeit still with a fluctuating vacuum reading. However the car is undrivable without the air filters popping and banging through the exhaust as soon as the throttle...

OK well hooked up the vacuum gauge and the reading was a needle fluctuating between 14- 20" of vacuum fairly quickly, the idle is still off it sounds like there is a stunble. I drove the car and found it backfired under acceleration, low power and hesitation, as you can tell I'm pretty annoyed...

Cheers for the information I'm of to hook up a vacuum gauge in an hour or so I'll post my results later

I'll connect up the vacuum gauge and see what it reveals

Many thanks for your reply. No as I thought an erratic idle wouldn't give me a very accurate reading, any idea what kind of vacuum reading I should expect ?
