Hi guys
still have a dam misfire on tick over and if i rev her up to about 2500 revs there is a misfire every second or so, can it be a tight tappet.
Thanks
vince
I had this problem a few years ago on one of my engines, must have been in the TR come to think of it, took months to find it.
I never thought of a vaccuum gauge, swapped all the injection and ignition parts twice, turned out to be a sticking bucket on one of the inlet valves,they were all new, swapped it for the slightly worn one that came out and the problem went away.
Frustrated the hell out of me, the bucket measured ok, must be something to do with the head.

Hi Vince, have you got one of those little devices that show if a plug is firing ? fits between the plug and the HT lead, try that on each plug in turn and watch for a missing spark, then change the offending plug and/or lead. I'm always in favour of trying cheap and easy first. If the plugs are new, that means nothing, I've come across loads of faulty new ones over the years. Martin.
