<DIV><FONT face=Arial size=2>Maybe the guys that make the filters can comment
on the carb size they work on. All the Mintors have ample surface area on the
carb inlet as their carbs are a bit taller than others. The Mintors out there
now have a slightly fluted inlet that is .54 in at the bottom and .6 in at the
actual inlet. If one of the rubber filters fits over the inlet, the
fluting will help hold it on. Mintor is coming out with an engine
update, the 170-1 that has some improvements to the carb. this carb has
a constant .64 O.D. inlet but has a groove 1/8" below the inlet for a tie
wrap. It appears they are planning for a carb filter in the future, or
to assist the installation of a currently available one.</FONT></DIV>

<DIV>Jeff Carrish, at <A
href="http://www.pattern-craft.com">www.pattern-craft.com</A>, makes a
filter that fits the OS 140s; Central Hobbies sells filters for most of the
YS 4-strokes. I don't know about filters for Webras or
Mintors--anyone else?</DIV>

<DIV><FONT face=Arial size=2>When we first started trying to quiet things
down, one of the areas we looked at was intake noise. We used to use
a stretch on filter housing with small filter disks that helped the noise
problems with the added benefit of keeping crap out of the engine--gee,
what a concept. Are there any such animals available now? We
fly off an old asphalt runway and there is the possibility something
significant was sucked into a brand new 170 and destroyed the piston,
sleeve, ring and bearing. First time for everything, I guess.
The 60 sized ones did not seem to affect
performance.</FONT></DIV>
