REFLECTOR: Franklin Magneto/inspection/priming questions

[Michael Watson]

I originally purchased a pair of the primer rails with all the fittings from
PZL, but only
used one on the right intake manifold through a solenoid. Before starting,
master on,
fuel pump on, activate solenoid for three seconds, fuel pump off then start.
Has
worked flawlessness for ten years +. Still getting 78/80 compression at last
annual.

I will consider selling the spare rail with fittings, but as Larry said they
are very
expensive.
