I don't have a way to ensure the mounting surface is flat, and most of 1/8" stock is bent every which way. Of course, thermal grease helps....25 is kind of thick for a heatsink, starts to become a heat capacitor at that point.

No, but I used the same technique on saxophone reedspiece of glass, water, sandpaper, time
I can't believe you never had to deck the head of some crusty 2 stroke bike
Commonly referred to as the Top Hat Piece. Royal PITA to replace.No, not the insulator. The shaft that the rotor rides on is not insulated in any way from the shaft that goes all the way down, but this little plastic thingy is supposed to keep the rotor shaft from sliding up far enough to disengage the mechanical advance.
I started looking at the distributor replacements - DUI is $600 and lead time is three months. Ordered myself a stock replacement, so I have one around for three Classics.
Speaking of spark coming out of the coil but not out of distributor... It can easily be distributor timing way off.
Well, today is National Saxophone Day!No, but I used the same technique on saxophone reeds
Shit... I may need to dig up mine.Well, today is National Saxophone Day!
Thanks for the update. Look forward to see how it progresses.Well... Updates on converting the ignition to GM HEI-style amplifier:
in short, negative so far.
A couple of weeks ago I swapped one in my son's 95 LWB. The engine started and ran beautifully. He called me back from different part of town later in the day and said the truck wouldn't start.
I came over and reconnected everything to the factory amplifier - everything back to normal. Did some Google fingerwork on Pertronix HEI ignition modules and decided it was a dud. Also, I thought it may have burned from ignition being on while the engine was off, with a factory 0.7-0.8Ohm primary coil.
Last Saturday, I decided to assemble another set, using a brand new 3Ohm-primary coil. I had another amplifier sitting on the workbench, but I wanted to test the old one.
Remarkably, the engine started on a dime, ran beautifully - until it warmed up and ECU lowered the idle. Once the idle went below 800 rpm, the engine would die. It happened several times, and no fiddling with other stuff helped it.
Not to blame the "Flamethrower Ignitor III" - I suspect the factory pickup coil output is on the low side. Since the amplitude is speed-dependent, it could simply not trigger the module when the idle drops below a certain speed; strangely, it started every time (at even lower speed) - maybe it has something to do with the ignition module running in multi-spark mode at a start-up.
Stay tuned for the updates.
Not really. I adjusted it as tight as I could without reluctor wheel hitting the coil due to the play in the shaft.been a while since Ive looked at one torn apart. can you adjust the air gap?

Yes, you can adjust the air gap!Not really. I adjusted it as tight as I could without reluctor wheel hitting the coil due to the play in the shaft.
Ordered myself a new baseplate so I could compare.
But I already did, Tom. No more adjustment - can't get it any closer.Yes, you can adjust the air gap!
Due to play in the shaft? Mine didn't have that, but only 56k on it at that point.But I already did, Tom. No more adjustment - can't get it any closer.
Yes 100%. Is that the top hat piece?Come to think of it, I don't have the plastic collar that should prevent the rotor shaft to lift. I should probably install it.
