My dear Badger,

What a pleasure it is once again to read your pearls of wisdom after an
unforgivably long absence from this list. Welcome back. BTW, this Crown
Prince of Tonga - is he the same cad who was disqualified from competing in
the famed Grand Prix of Gibraltar (circa Peter Ustinov) for having his
engine blown by several lusty maidens?

As ever

Joe

I often wondered if this method would work with SU carbs. I can see it
working with a carb with an accelerator pump but not sure with an SU or even
modern fuel injection. But what about accelerating with the choke pulled
down on the SU? That would enrich the mixture to do a wash possibly.

Ummm
Sorry to inject this, but usually I just hone the cylinders to size using
the correct cross hatch pattern. I use chromoly rings which seat instantly
upon light up. The chrome portion gives good longevity.
Perhaps investigating newer designs of rings might be worthwhile for those
who are building their own engines.
If the engines are built using correct clearances, careful attention to
details such as ring-end gap, weight equilization, volumn equilization, etc.
you won't have to dump sand down the engine to "seat" (ruin) the rings.
Pulling the engine back out is a pain. If it is done right the first time,
you don't have to do so.
Now, if you have a engine that the rings won't seat, pull it out and make it
right.
Best,
Ray
