Paul,
  Techron is an additive sold by Chevron in bottles as well as

in

some grades of their gas at the pump.  It's supposed to be the best

of

the

'add to gas' injector cleaners.  The local VW dealer recommends it

over

the

VW product...  FWIW

  Hard to predict.  Possibly some 'not OK' interactions with some of the
elastomers in the system.  I can't recommend it, but I *do* use it in my
Porsche and other carbureted and FI cars for many years.  Some A/C
elastomers are OK with 100LL or 80, but can't deal with some auto
fuels.  OTOH, I have operated my A150 on autogas for many years with
no ill effects, except to the local airport fuel supplier's profits.

Probably

OK, but you'd be a test pilot.

Bill,

    Thanks.  I'll keep pulling the injectors every 50 hours and using
ultrasound and MEK on them.  Tom

I understand Hoppe's No. 9 (gun cleaner) works great, from a now
deceased old-timer, no personal experience.
