My feeble mind says that depending on where the engine is when it stops,
if the ignition is firing, pushing the piston down, while the starter is
trying to push it up the starter will drag. If too many pistons are doing
this at the same time, the engine will be difficult to crank. It can
happen when its cold too, but usually is more noticeable, and likely to
occur when the engine is warmed up. Over the years I have been in this
situation a number of times. Correcting the timing has reduced the load on
the starter.
My father actually once talked a guy he worked with into rebuilding the
engine in a car that was doing the same thing, after he replaced the
starter. My father, who is a mechanical engineer, convinced the guy that
he had a spun bearing, and that the engine was going to seize, even though
the car ran fine once it started. The new engine didn't fix the problem.
Further discussion led to the fact that the guy habitually advanced his
timing, even on his new "long block" engine, a little bit past factory
specification to get a little extra "UMPHF". When he backed it off, the
problem went away.
As I have explained before, my knowledge is based on practical experience.
I am not an engineer, chemist, or scientist. What I share has worked for
me. I road time my cars, I do not use a light. When they are too far
advanced, they spark knock, which is damaging to the engine. They can be
difficult to turn over, particularly when warmed up. There are several
different problems that can cause this same symptom. I am suggesting one
idea that might correct it.
In your shoes, I would back off the timing and see if the problem went
away, before replacing the starter, especially since you know that the
timing is advanced..

Sorry Paul, but I don't understand...
How can the timing influence the rotation speed of a starter motor??
I must admit that my timing is too advanced hower, it's about 12.5 degrees
BTDC instead of the recommended 10 degrees. That is because the engine is
running on propane instead of gasoline.
Since propane has a much higher octane rating then regular gasoline it is
safe to advance the timing a little, and it gives the engine more power.
But I don't understand why this also influence the performance of the
starter motor when the engine has been warmed up ?
Maybe you can shine a light on it for me :)
Thanks,
Robert

That will also happen if the timing is too advanced. Try backing it off
a little and see if the problem goes away. Heat shouldn't effect the
starter that much.

OK James,
I understand, maybe the best thing I can do is to find me a reputable
rebuilder and send him my original starter.
You see, mine is having problems when it is getting hot. The starter
spins perfectly when the car is cold, but when the car is driven for a
while and the engine has warmed up it turns around very slow.
If you wait for an hour or so the starter will act normal again :)

Hello, no I havent I think its not worth all of the opposition and the
hassle to go with the little outcome of the result. The msd ingnition
system has to be on its toes. To have the least effect against my
oringinal starter. The header issue isnt worth the gamble when Im just
going to use it for cruisins, and some kind of shows .My motor is
allthat and im not going risk nothing because everything shiney and new
will make you feel that way.

Hi James,
Have you actually found another starter for your 60 already?
I am still looking around for the best option you see.
Thanks,
Robert
