Hi Karl,
I assume that you have checked for a loose plug cap. They will come off.
I am just replacing my bottom caps which seem to be more susceptible to
working loose. The caps are obtainable at http://www.clubplug.net/ for
$6.30 each. The NGK 5 K ohm resistor cap part no. is VD05FMH.
(Lockwood's price is $53.34!!)
Another possible cause is a broken wire at the multi-pin connectors on
the ignition modules. On early engines, there was a common problem with
breaks inside the small inlet grommets due to a tight bend and vibration.
Cheers, John

Has anyone come across this ignition problem before ? :
In my usual runup I noticed that the engine is vibrating like mad on one (L
) magneto and there seemed to be some backfiring going on.
The engine runs fine on R and on BOTH.
For example at 2450 on BOTH=2C I get 2370 for R and 2150 on L.
What am I looking for ?
Karl
