<VV> Axle shafts, wheel wobble & detonation.

[Hugo Miller]

It's a 64 convertible. I said that. And it's in Florida. I said that 
too! I am from the UK and sort of commute between here & there, and I do 
have a Corvan in the UK, but that's another story.
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.
