Another nice set-up Jim, that ball top engine seems to be a favorite from those who have one.

Its been by far right out of the box the best H&M engine that I own.
I was only ever going to delve into these by having just one :)

B01 Ball Top Monitor Gas Hit & Miss Engine Driving an Old Antique Pericaud Water Pump via a DIY Homemade Transmission that I made some years ago. The Transmission slowed the pump down nicely and was well matched to the H&M engine and this is one of the jobs these types of engines would have done back in the day.
