RE. OIL RELAY IGNITION GOVERNOR. X. 8685.

Regarding the above we suggest that you fit up a strainer with some very fine gauze and observe its effect on the action of the valve, and the rate at which it chokes up due to the dirt in the oil. We are proceeding to scheme a strainer of larger capacity. We have not got an alternative scheme of valve at the moment which is balanced.
