Re: [T3] Just how hot is too hot?

Yes, the timing used to be way too advanced.  I fixed that problem about a 
year ago.  I replaced the voltage regulator a few years ago. It still reads 
around 14 volts at medium rpm.  The reason I think that it's getting too 
much gas, is because it gets terrible mileage.  Stunk like unburned fuel 
when I was trying to start it.  I had to hold the throttle wide open for it 
to start, and then keep the rpms up to keep it alive.  If I understand the 
way the throttle position sensor works, when you depress the pedal it sends 
a signal to tell the injectors to squirt extra fuel.  When I would depress 
the pedal quickly, it would almost kill the engine.  The auxiliary fuel 
injector in the air distributor has been disconnected for years, so that's 
not the problem.  I still don't have a pressure tester for the fuel system, 
but I have always assumed that if anything it is too high, just because of 
my poor mileage.  I had a ripped apart intake belows, so I recently replaced 
that.  It is sealing well now.  All of the engine tin is there and in place. 
 The spark plug boots are there, but they are hard, and don't seal 
extremely well.  I just adjusted the valves to .006" on intake and exhaust 
at the last oil change.  I just replaced the vacuum advance on the 
distributor last month.  The mechanical advance seemed to work smoothly, 
too.  (turning it by hand and letting it spring back)  I have it timed at 0¡ 
right now.  That's what it should be for a '71, I beleive.  It does advance 
smoothly when revved.  Right now I feel very betrayed by my car.  I just 
spent several hours last night washing and waxing it.  This is how it repays 
me.
