HT leads?

[sean5gtt]

My H-reg r5gtt suffer misfiring when drive it for at least half hour or so, but start up 1st try when cold or when engine hot, it's start ok.

Possible cause is HT leads but wonder if it is not the cause for misfiring? Ingition coil or AEI (ECU) or crank sensor?

I am trying to get everything spot on before I sell it.

check , spark plugs , HT leads , give your Distributor cap a clean inside

Most likely be duff leads, dizzy cap worn out or sooted up plugs. Make sure the carb isnt flooding the engine with fuel.
