Hi Paul,  I just got off the phone with the Barry Mount factory rep.  in
Mass.   When I told him I wanted the 140lb isolator  he said there was
no such thing.  According to a chart which I downloaded the 20002-11
mounts are rated at 130 lbs.  I told him that the engine weighed 300 lbs
and he recommended the 20002-12 isolators which are rated at 175 lbs.
He cautioned me against overloaded the isolators as they would break
down.  He said that two 175 lbs isolators would dampen the movement of a
three hundred pound engine effectively.     That is what I ordered.

Another complication is that the mounting bracket needs to be .563
thickness so it will have to be machined out of heavier material.

175 pounds sounds fine with me. The 140 number was from memory which at my age
is getting unreliable. Just make a 2.5 inch dia. .065 thick aluminum washer 
and bond it to the 1/2 inch plate. Unless of course you REALLY WANT to machine the
rubber mount holder out of 5/8  or 3/4 aluminum plate on the NC mill :-)>

I don't think it is all that important and I will try the 1/2 inch plate first.
It is something that can be easily changed later.

I think the Barry rep is being overly conservative and covering his ass.
