Have been following this message and want to inject a question here.
About a week ago the hot topic that Ian started and I added to was that
we, along with a few others, were having a problem where the starter
would hang up, seemingly near TDC. The deduction was the Marelli
starter having weak springs. This message here hints that the ignition
timing can be too far advanced causing the starter/engine to turn over
when warm. So which is it? Or both? I believe my mechanic timed my
Ambo (will double check). I did have some pinging on the highway when
under load, but I attributed this to either bad gas, or as Pat Hayes
stated, all loops will ping because they lack valve seals. Now I'm
beginning to wonder if the timing is off a bit which can be causing the
pinging and starter problem.

Any thoughts?

Thanx!

Gap and then set it so that with the timing marks lined up on the front
set
the points so that they are just opening.

dept of obvious: don't hold on to the distributor cap and crank the
motor
with the key to see how it operates. I got tired and careless. I have a
VERY
healthy coil.

Andy,
Good thought. I did the timing myself, which is probably not a good
thing.
I will try to retard the timing a bit. Thanks Andy, Bob

bob-
do you mean that it 'turns over really slow when warmed up'? -- if the
ignition timing is too far advanced, that can cause this symptom, too.
just
 a thought.

Peter,
Sure glad to hear that your experience with a loop is a good one.

I finally got the starboard cylinder to fire pretty consistently by just
changing to proper carb jet size - #60s were in there and I installed
#45s
 as per Mark's suggestion. Big difference. Now the bike won't start when
it
 is hot. Perhaps starter or coil. Will continue working on this. Wish
I
 was a mechanic someimes. Best, Bob Hawkes

Got 600 mi in on the 71 since getting it on the road 4 weeks ago.
Initial
 
 shifting problems ( not finding neutral, popping out of gear) has gone
away.
 Probably the rider has learned how to shift without beating up the
linkage.
 The sneezing or one missed firing seems to have stopped in the last
200
 mi.
 Maybe there was some crud in the carbs. I haven't cleaned them yet.
I learned I have fuel for 4 miles in reserve before going bone dry.
Brakes seem to have seated in pretty well. Much better than when I
started.

All in all I am pretty satisfied with the performance. The bike has
not
 
 been registered since 1978, so I dont think it got much attention in
the
 
 past 20+ years. All I had to do was put in new tires, brakes,
battery,
 
 brake and speedo cable, plug wires, horns and added horns an light
relays.
 
 replace corroded terminals and add directional signals and mirrors.
Grease
 head bearings and rear drive, synch the carbs, change fluids and it
all
 
 seemed to work.

I haven't touched carbs or timing or guts of engine or trans.

Future plans: replace left header pipe ( restricted), tap in some
fittings
 to allow vacuum synch'ing, add tube for 1 petcock to give some
reserve
 
 range, check timing, try hotter plugs, add highway bars, new solo
seat,
 new
 rear shocks. Fresh chrome parts and paint ( way in the future)

This has been a great experience so far. Thanks to all who have
directly
 
 helped me with advice and support. And thanks to all who have asked
questions and those who answered. Its been a great leaning experience
just
 to read the exchanges. Its too bad I cant make the W NY rally in
June.
 
 Some day, I'll meet you guys
