<VV> Axle shafts, wheel wobble & detonation.

[Doug Mackintosh]

Hello, Hugo!The baffles are (supposed to be) on the bottom side of the cylinder barrels.
As to the wheel shimmy, try moving some of the tires to different positions to see if it moves where the vibration comes from. If it is a front wheel, swap from front to rear to see if it moves. May not be the most likely cause (although the speed you mention is typical for an out of balance tire, and my experience with the Maxxis tires is they often have this problem) it is easy to check.
I would also check your timing. Again, may not be the cause of your overheating, but it is easy to do to eliminate that. Even if you don't put a light on it, you can do a static setting to get it in the ballpark. Just take the distributor cap off, use a wrench to rotate the engine till the rotor points to #1 and the mark is aligned with the correct timing mark, pull the coil lead out of the cap and hold it close to ground, turn the ignition on, then rotate the distributor clockwise past where the points close, then rotate back counterclockwise just until the points open and your coil wire sparks to ground; lock down the distributor.

Yes it detonates when it gets hot. But it also detonates before it has
even warmed up. That is the bit I find puzzling. I haven't even taken
the plugs out yet, as I have more pressing things right now - such as
the fact that the idle jet on the left carburettor is blocked so it
won't idle.
I thought the baffles were above the cylinders? Although I've never
looked in there before. I have a couple of these cars & I've just been
running them while I decide what to do. Now I'm getting stuck in.
Funnily enough, my other '64 convertible has also started overheating,
which it never used to do before. I haven't looked at it yet though.
When the wind blows here in Florida, the entire top of the engine can
get buried in leaves to a depth of six inches, so I wouldn't be
surprised if some have taken up residence in the fins. I'm just
surprised that I didn't find any (yet) on the one I looked at.>>
