Hey gang,

I have an engine question, but related to the '88 Convertible I just bought
not an aircraft.

The car starts normally, not excessive grinding like a typical low
compression engine. There is no smoke, typical of bad seals, but it has no
power to speak of. I've owned three other 88's (even a clone to this one so
weight is not at issue) and this is by far the slowest. The engine is
"tired" for sure, with over 180k on the odo, (this is an all-original,
one-owner pampered hangar queen, with all freeway miles) but my question is,
what exactly is "tired" with a rotary?

I would imagine that new seals all around are in order, but where is the
blow-by, and if it is a compression issue, why does it start so well?

Thanks!!!

Pat
