Maintenance questions

depending on the Mag, there is a service AD for the magneto on the impulse
coupler fly weight tolerances (or something like that). I'd ask about the AD
and ask if your mag requires that inspection. I think it is due at each
annual.

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.
1300 Clydesdale Avenue
P.O. Drawer 2365
Anniston, AL 36201
800-525-6408
Fax 256-237-1579

FAA Repair Station # IPBR525K

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?
