I have only used Bosch W5 AC plugs for a very long while
it is the recommended plug .
for both standard compression and high comp motors ,
do not have a problem with them .

Thanks Kerry - my handbook has the specified plug as a Bosch W225T1 and I have never found them. I believe the NGK equivalent is the one I have but not sure.
I might give the one have specified a try.
Cheers

that's interesting . as all i have specified is the bosch W5AC
and that is in original paperwork .
but a lot of other things can affect the running .
other than electrical , carby is very common .
and often it is the butterfly shaft . worn and sloppy holes changes the mixture a lot .
rebuilt a number by machining and fitting bushes in the carby body .
it makes a huge difference .
i can just turn the key and have a steady idle , hot or cold
