Excelsior Monarch motor mower

As you may know I purchased an Excelsior Monarch through Tony Hopword with  Villiers twin exhaust ports.  Is this rare, as the pamphlets I have looked at show only one exhaust port.

Hello Dusty,

I dont know too much about the subject but I have seen twin ported Villiers engines used in two man chainsaws, Teles Smith certainly used it it one of their machines. The ones that I have seen where a bit of a handful so I guess your mower will have a bit of power when you get it running.

Have you got information about the engine or are you looking for some?


The link will take you to the saw that I had in mind

R.E the twin exhaust port

R.E the twin exhaust port head, Its my thought that at some point down the line the original cylinder was damaged and replaced with whatever matched,in this case i would wager its a Villiers motorcycle cylinder head. I guess its twin exhaust ports your talking here?
