<DIV><BR></DIV>You might still be able to get parts from Performance
Specialties. If not, there are lots of guys around who have parts from
when this was a common pattern engine. Problem is prying them loose from
guys who still love these engines and have several in good running
condition.<BR><BR>Gooc luck <BR><BR>----------<BR>From: <<A

<BLOCKQUOTE>To all those that replied…<BR> <BR>Having the luxury of
living 3 miles from my office, I came home for lunch and promptly opened up
the regulator body.<BR> <BR>Although there was no sign of swelling or
disfigurement in the diaphragm, I did note a very fine hairline crack where
the diaphragm contacts the ridge of the seat for a seal. It was in a number
of places around the edge of the diaphragm. You really need to look close as
it wasn't apparent until I pulled at the side gently. I promise from this
point forward to never, ever, use Prather in my YS engines. The YS Gods were
not pleased with me…ahh…<VBG><BR> <BR>I did replace the diaphragm
and plunger while I was at it and noted it was fairly clean. I will try it
as soon as the weather clears. Might have to wait for the weekend due to
rain.<BR> <BR>Since I have three of these engines and would like to
keep them operational, where can I get replacement
parts?<BR> <BR>YS1125 - Regulator Gasket (Need to replace this one now,
plus a couple of spares)<BR>YS1145 - Plunger<BR>YS1130 - Diaphragm<BR>YS1150
- Regulator Spring<BR> <BR>Or any other gasket sets for the YS 61R
LS…<BR> <BR>Thanks to everyone that replied. I will let you know how it
runs when I get the chance..<BR> <BR>Larry<BR>

probably ruined your diaphragm with the after run oil - you can only use
a non petroleum based oil like Ultra Oil. Replace it and try the
following setup:<BR><BR>APC 13X10 (windy conditions) or 13 1/2X10 (calm
days) prop.<BR>15% nitro.<BR>O.S. #8 plug or K&B 1L.<BR>Hatori 650
pipe.<BR>>From the glow plug to the first ring on the pipe measure 20
inches straight back.<BR><BR>This should idle way down and provide
plenty of power for any airplane up to about 9 lbs. dry. Throttle
transition S/B excellent and downlines can be very slow with the larger
prop at low idle. <BR><BR>Hope this helps, Bill

<BLOCKQUOTE>OOps, <BR>wrong click on the last one.<BR> <BR>I am
not an expert, but here goes.<BR>The idle is still a little too high.
My YS 61LS idled at 2000rpm with 13x8. I could go
lower.<BR> <BR>Have you checked the Diaphragm?<BR>As basic
maintenance, cleaning the needle valve assembly is also a good
idea.<BR> <BR>When I take out a previously stored engine, I try
to clean out the oil (I use Mobile 1 Synthetic oil) with fuel.
Remove glow plug, use starter to turn the engine that was hand
primed before using starter. Flood it so that the old oil get
mixed with fuel and drained out to plug hole. (Make sure to
cover the plug hole with rag to prevent fuel/oil
splash).<BR> <BR>I am not sure about Prather's after run oil.
never tried it.<BR>Also, I don't use castor anymore. I had
to clean one of OS pump because of the castor residue.
<BR> <BR>Hope this
helps,<BR> <BR>Ihncheol<BR> <BR> <BR> <BR> <BR>

Help on YS 61R Long Stroke!!!<BR><BR>I'm having problems with the
engine leaning out on transition to full throttle. The engine is in
a 60 size pattern plane. The set up is unchanged from when I bought
it. However, both engines have been sitting in a sealed bag after a
good oiling with prather after run oil.<BR> <BR>The pressure in
the tank is fine and builds up to 6psi, measured on a pressure
gauge. I'm confident that there is no air leak as it holds the
pressure in the tank. Idle seemed to be very steady with no sign of
dying at 2,700rpm Would also like to know where the reliable idle
RPM is..<BR> <BR>I allowed the engine to run for about 15 to 20
seconds at about 4,000rpm and as I slowly increased to half throttle
or about 7,500rpm, it would immediately die. I took the head temp
and it was about 250F. I changed the engine out with a back up and
it did the same exact thing. Again, same results on both engines. I
also change the glow plug and as expected it didn't change anything.
I haven't checked the fuel filter, but I will shortly. The
regulator is adjusted to flush with the case.<BR> <BR>The
original engine had about 25 flight on it ,and the back up is a
brand new rebuild with new piston, sleeve, bearings,
etc…)<BR> <BR>Setting aside the fuel filter, is there anything
else that I'm missing?<BR> <BR>Wildcat 15% Nitro w/ 18% Oil
