Okay, the Cherokee 140 annual is nearly finished. Compressions are 80, 80, 80, & 78 over 80 after 5 1/2 years and
650 hours of mostly autogas use.
So far everything looks very good except for two things. My A&P IA was inspecting the propeller spinner back plate
and was turning the prop real slow by hand as he did so. He noticed that the impulse coupler on the left mag wasn't
clicking. He turned it a little faster and it works fine. Tried it slow again and sometimes... no clicky. Since
I've had no starting problems, he suggests I just keep flying it unless it begins to give trouble. The mags won't be
due for overhaul for at least another year. My question is: Is there a slow death type "normal" failure mode in
which progressively harder starts occur or do impulse couplers usually fail suddenly and leave you stranded? I
really don't want to throw away money. On the other hand I'd rather not get stranded after dark at an airport away
from home with no mechanics around or parts to be had.
Question #2 The nose strut is not leaking, but there is a spot in which the chrome plating is beginning to blister.
It is hard to see and is low on the strut where it would take some extremely hard braking or a big bump, (or one of
my not so good landings, come to think of it) to get the top portion of the strut to pass over it. Eventually I
suspect, it will need attention. Is it still possible to have these struts rechromed? A Google search turned up a
post from 2002 listing these guys:
Industrial Plating Co. Inc.

Anniston, AL 36201
800-525-6408
Fax 256-237-1579

Can anyone who has had this done in the not to distant past recommend additional business possibilities and perhaps
relate a cost to do it?
