<VV> RE: Two Questions

[FrankCB at aol.com]

Smitty,
    Your "electrical mod" should only affect vacuum  advance at IDLE (by 
disabling it) so I don't see how it can have any affect on  the timing once you 
accelerate OFF idle speed assuming you didn't make a change  in the BASE timing 
(vacuum advance disconnected).
    INHO you can add "women" to the "children and dogs"  mentioned in your 
Second Question.  But don't quote me on  that.<GGGGG>
    As you are finding out, the WORST problem to  rectify is the INTERMITTENT 
one that disappears when you go look for it.  I  remember one Corvair whose 2 
carbs I had just rebuilt developed a loss of power  but only on hard RIGHT 
turns.  As soon as the car straightened out from the  turn, the power came back. 
 Of course, I figured it was due to my faulty  efforts on one of the carbs.  
But one morning the intermittent problem  became a PERMANENT problem when the 
car refused to start.  I discovered the  ignition wire to the distributor had 
faulty insulation and on hard right  turns would move left and ground itself 
out, cutting the ignition (this was a 66  A/C equipped car).  But this morning 
it stayed in contact with the ground  preventing the car from starting.  Once 
the problem became permanent, it  was simple to fix.
    Good luck on finding your intermittent  problem.

Smitty  Says:  I made the electrical mod to the vacuum advance system for  
throttle tip-in.  Didn't take the car out and test it even though I knew  timing 
might need readjusting.  Had to go out to a meeting yesterday so I  was 
watching to see what effect the mod might have on driveability.  It  was a real eye 
opener.  (big smile)  What had before been a very  docile pleasant car to 
drive in town immediately became pretty balky off the  line.  At one point it 
left me sitting wide eyed in the middle of an  intersection, watching traffic 
bearing down on me as I backed off the throttle  (against every instinct) to let 
the engine catch again.  Looks like I was  right about needing to mess with 
the timing.
Second Question.   Just like children and dogs, they never do what is 
expected.  Corvairs  are the same.  Ever since I wrote to VV about the electrically 
powered  run-on of the engine after the key was shut off, it has performed as  
designed.  Every time I shut the key off the engine stops  immediately.  
Somebody is screwing with me.  I would suspect the  "big" Beef or one of his 
henchmen, but they live so far away.  I'll get  back to you on what I find if the 
problem comes back.
