I'm looking for the correct spark plugs for a couple of my machines. One being a MS5151tc top hand chainsaw, the other a KM 130/R. The manual for the MS5151tc says 0.5mm GAP

I can confirm both models have the same spark plug. MS 151 TC-E - CMR6H https://www.lsengineers.co.uk/catalog/product/view/id/5420 KM 130 R - CMR6H  https://www.lsengineers.co.uk/catalog/product/view/id/5420
