i doubt they skimp,bosch plugs would be ok say one hotter for the number,i have a few two stroke petrol yard tools and bought half a dozen densos,they all take the same plug,my uncle bought a no name chain saw with a no name plug in it,,he couldnt start the thing only from lack of experience,he brought it to my place and i fired it up within four or five pulls,i was looking at the plug and the centre electrode was way out of centre and leaning to one side,i told him to buy a plug with a name on it,he got a champion from the hardware store,itll be better than the no name one by far!
