<DIV><FONT face=Arial size=2> Yeah I know it doesn't really matter but... I
MAY want to use a 140 Rx in this airplane later. As it stands now if you put the
OS 120 on the mount using the most forward mounting holes the distance from the
firewall to the spinner back plate is only 6 1/8". I remember the "standard"
disatance being 6 3/8", that's why I'm asking the question. I know I can make it
all work just fine but what if I want to change the engine later? It would be
nice to just bolt it in using the correct holes in the mount. If I knew exactly
which holes to use for the OS 120 that would be fine assuming that there are
also other sets of holes that would work for any of the compatible engines AND
position them exactly the same distance from the firewall. That's my
understanding of how a "universal" engine mount should work. So... if the proper
holes in this mouint for the OS 120Ax are the forward ones I'll just line
everything up accordingly.</FONT></DIV>

<DIV><FONT face=Arial size=2>I'm not positive about the 120 size, but the 2
meter size is set up for a standard 6 3/8" distance. This was just sort of the
number we agreed upon a couple years back. It seems to be a compromise that
works ok for just about everything including some of the more obscure
stuff.</FONT></DIV>

question</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial size=2>I'm setting up a new airplane with a Hyde "Firm
Idle" Type 'C' mount. I'm using an OS 120 Ax for this particular
installation. There are a few sets of mounting holes on the beams. The OS
120 lines up with 2 of the 3 sets. One is located more forward than the
other. I'm wondering which set of holes I should use. From what I
understand, this is a "universal" mount and depending on which engine you
use and which holes you use, you should end up at the same installed length.
That way, theoretically, you can install the mount and swap engines without
changing the spinner -> firewall distance.</FONT></DIV>
<DIV><FONT face=Arial size=2>Has anyone used this mount and if so, what is
the "standard" installed length? </FONT></DIV>
