In about 25 years of restoring and maintaining CJ=99s I can not recal l ever having used this. When you overhaul the unit you have the choice of retaining or discarding t his feature. Walt From: A.

Hopefully we will be able to discuss this and other more pressing world issues over some good Canadian whisky (his, not mine). Because the QDF-1 start solenoids are widely used on the air start systems in the marine industry in China NEW QDF-1 valves are getting hard to find. This has caused me to establish contact with the firm in China which overhauls these units for the PLAAF. While all seem to be of high quality, some of the overhauled valves which I have received have had the levers and some have not. *However 100% of the factory NEW valves which I have received to date have had the levers. * This indicated to me that the removal of the levers is perhaps something that is done at the unit level in the PLAAF, and not at the factory which manufactures the valves.
