We need to know exactly what engine you're referring to. Is it a "Rider" engine with the flywheel between a hot and a cold cylinder or an "Ericsson" engine with a walking beam and single cylinder? Both were made by the "Rider-Ericsson Engine Co.".

On the 10 inch rider I do not think they are 90 degrees off I think it is greater than that but do not know how much greater . also I think the stroke on the hot side is longer than the stroke on the cold side .. I have A 10 inch Rider here I will be taking the cold piston out in about 3 weeks to work on it on and can get closer measurements if needed Buster

This 10 inch rider has A tag says Rider Ericsson also has one more tag where it was shipped to Australian Branch Sydney . N.S.W Buster

Bill, is the valve the same in all sizes of the engines? We are working on an 8 inch here at Jacktown and when pulling it over it seals very well, but when running it seems to not seal and actually taps consistently on each revolution.

Alan,
I don't know if the valves are all the same or not. The valve is supposed to let air into the cylinder to make up for leakage so I think it is normal for the valve to open on every stroke.

The snifter valve on the 10 inch rider engine Is larger than the ones I have seen on the 4 and 5 inch engines The reason they are there is to replace air lost by leaking leathers . If the seals are very good it works very little if the leathers leak you can here it pop every stroke If engine still starts good and runs good that is fine . The bottom piston seals are for compression stroke . The biggest job for top seals are to keep over lubrication from going down into engine .. If oil gets by on hot side it will burn up if it gets by on cold side it will gather in bottom of engine and can be drained off from plug on side of base next to bottom of engine . This does not come from Books it is just my way of thinking and is open for correction Buster

I would recommend On A rider engine ..Putting A tee and ball valve between the engine and the sniffer valve to let in outside air In the event it is over fired and starts to run to fast on A 8 and 10 inch I would use A 3/8 Ball valve on A 5 and 6 use A 1/4 inch valve. Nice RPM for A 10 inch at A show would be 60 to 80 RPM Buster
