RE: OS Max-H .40
Dave, another great engine, good work! I have 4 of those Max 40H's, both normal ring & dykes ring. Which version is the one on test?
And no, we don't mind you "posting all this stuff" - in fact, I positively want to encourage you & others to keep doing this - get the old engines out of the cupboard, clean them up & run them [8D]
I have some Taipan 15's & 21, 2 handfuls of OS engines from the 60's & 70's, Irvine 40's from the mid 80's (23 years ago, so it's sorta old) & sundry others that escape memory at the moment. Better give them a run & report back.
