Do yourself a favour and change the condenser. I have just spent money and a lot of time changing to an unleaded head (which needed to be done sometime) only to find the problem of backfiring persisted. A new condenser cost me £3.50 and problem solved. The old condenser was in a distributor which I bought as a recon
only a yearYGYA or two ago.

I will get another one. I have found that replacement parts like indicator flasher relays don't last very long.

Many thanks for advice. I'll update this Post when I solve the problem.

Yes 10 degrees before TDC. The misfire caused a 10 degree after TDC reading (strobe light).

I'll be replacing the distributor condenser over the coming weekend.

Yes, you are right - complete opposite. It will something else then.

Hi all

I had a very similar problem and it was the rotor arm. The arm fitted was brand new, put an old one in and been fine ever since. I was talking to Dennis Roberts @ Donington last year and he has had similar experiences. I now carry a spare!!

I wonder if fitting electronic ignition might help ensure against future issues once fixed?

Many thanks for suggestions on Rotor Arm and electronic ignition. Hopefully I find a solution this weekend!

Hi Mike.

Very curious as to how you got on - and what the culprit was!
