Valve clearance max 4hp

[Bootsy]

As the title really just got a Hayter mower with the above engine, would like to know the valve clearance`s if any one knows them, also the type of plug and gap.

Plug gap isn't very critical. 0.030" is what we see most recommended but I've found 0.020 - 0.025 works well too.

Thank you very much SeniorCitizen for the info.
