[AT] 430V Update and misc.

[Dean VP]

I suspect a major contributor now is the inability to get good torque on the
crank shaft.

Sorry to hear of June's husband, and thanks for the advice.   I do already
have the rocker arm assembly off, mainly so the valves could close so I
could try adding air pressure to the cylinder to help force penetrant down.
Exhaust valve leaks too much for that trick to work but I have left the arm
off.   All the valves operate smoothly  by the way.

Take care!

while towing it home because found stuck valves. It would had been very
costly otherwise. PS: June's husband passed away a few weeks ago. Joe

have soaked it for more than 3 months.   I have switched to pure penetrant
for soaking.  I have tried several methods of force and nothing is budging
it.  I haven't tried dragging it, which is always a last resort in my mind.

light-bodied penetrant but I'm thinking the fluid won't stay in long enough
to penetrate the rust( I get a rise in the dip stick level too).  If I put a
thicker fluid in it i don't think it is penetrating because the fluid level
doesn't change.  I may have to at least pull the oil pan.

total hopeless cases that require the pistons be broken out or hydraulic

have a bore scope and I don't believe anything I have seen would indicate a
difficult unsticking job.  So I am mindful of the idea there is the small
possibility the lock-up is somewhere else.

girlfriend's younger brother. He had the carb off and it rained on it.  To
be honest I don't remember if it was a stuck valve or engine.  If I have to
be honest, it ran like crap after that(I was still honing my mechanic
skills).  I also remember what her mother said:  "all Julie's other
boyfriends say stuff and never do it.  You are first one that doesn't say
anything and does it".   I got serious boyfriend points with the mother
because of that mini-bike. They were a conservative, religious family and
public dances were not their "thing".  So I still think fixing that minibike
got me a date with the daughter for the homecoming dance. :-).   Funny how
those memories become sweeter over time.
