spark plug gap?
The gap for a specific plug is more dependent upon 'engine factors' than the plug itself. Factors like; compression ratio, fuel / air mix, capacity of the coil, top engine RPM, engine temperature, etc.
Plug gaps for similar 230cc air cooled engines run from about .025" to .035". A 'typical' good setting would be about .028"- (contrary to popular belief it is better to err to the smaller gap than too large a gap, especially as the tips wear).
A good source of plug technology information is on NGK's website. See attached;
