The 66cc skyhawk kit used to come with 2 spark plugs . One was a standard single electrode spark plug and the second was a 3 electrode . I've serched hi and low to find the 3 electrode plug and cant find one . Can anyone tell me where I can order one or possibly tell me the make and number of it . My motor runs perfect with that plug but I get consistant engine spatter at steady speeds with the single electrode
