Hi all
was just wondering if anyone could tell me the spark plug number for this G20 stationary motor,It works well but the son decided to clean out the shed while I had it stripped down to clean and he threw out the plug I beleive it is about in the late 60s stand to be corrected on that but i think the plug is a long shank any help would be appreciated
132 cc G20
100822
G20 3PS/4000 R.P.M output

That one is too old for any manuals I have. However I see there is someone selling spark plugs for it on ebay, and he says the correct plug is an NGK B6HS:

You might try cross-referencing this in a spark plug recommendations manual in your local speedshop.

Absolutely right !
