[f-AA] Short spark plug

[Scott Johnson]

I have run into this when I was using only before burning auto gas/mmo
mixture.  Dropped the valve out of the cylinder, cleaned the stem, and
reinstalled.  Ops check good and have not had a re occurrence.  If you end
up removing a cylinder the AD 95-05-05 for rocker shaft bosses does not
apply.  (if it's a 65 hp).

Hi.We are doing our annual on Moya (1946 7AC) and the IA I'm working with
said I should put the Short plug in the front cylinder.Can someone tell me
the numbers for it and a good supplier for an A65.I've got one cylinder
reading low (45/80) and we can hear the air coming out the exhaust.The
others all read 71/80 and have about 500 hours on them.He seems to think the
valve is sticking becouse I run mostly pump gas and don't use(sorry to start
any wars ) MMO.We're going to run the motor to warm it up and check
again.Has anyone else ran into this problem before. Thanks. Bill in N.H.
