First of all I want to thank those that replied. Every idea I received gave me
something to consider. Here is where it's at today:
After running up to 1500 RPM. I used a can of starting fluid and sprayed every
nook and cranny. Pretty much every where except in the carb inlets (ok just a
little to see what would happen)(It bogged). I heard no change at all other than
that. When I wasn't spraying I was watching CHT's and EGT's. CHT's could not
get warm enough to even get into the green. EGT's could barely get in the green
if I ran up to 2000 RPM and let it go for awhile. Sounds like a very rich
condition yes???
Now for a little back ground: I bought this airplane from a couple of good ol'
boys in St. Joe, MO. (That is a story in itself). Now mind you I have nothing
against good ol' boys from St. Joe......... When I got I home and got down to
details. I found a lot of things not acceptable to me. I have never heard it
run or saw it fly. Normally a red flag but I got it so cheap I couldn't pass it
up. My wife would argue but I still think it was worth it. Any way enough rambling.
Both carbs have main jets = 158, Idler jet = 45, Needle jet = 2.7, Jet needle =
1K2. The top ring of the needle has the O-ring and the clip right under it on
the second ring. The air screw is at .5. The floats arms are level when the carbs
are upside down. I believe I have the recommended 1/2 inch of space between
the top of the float bowl and the gas level in the bowl.
Altitude at Stevens Point, WI (5 miles away) is 1050 ASL. The three finger test
mentioned in my last post still has me scratching my head. It tells me that the
carbs are still different in some way. Is a K&N air filter considered a "silencer"?
Thanks every one,
Ray W.

Every year at this time there is a Santa train that runs through Appalachia and
ends up at Kingsport. They always have some celebrity on it throwing candy and
trinkets out the back, and the kids at each stop are waiting to catch the goodies
- sort of an Appalachian Madi Gras... this year it was Wynonna Judd as the
resident celebrity.
Here are some pictures I got of the train in Fort Blackmore, VA. about 20 miles
north of here, another one coming through a tunnel, and one crossing the big
trestle just north of Clinch Mountain.

Hello,
I cannot seem to find a Rotax 503 repair manual for purchase. Does any one know
of a source. It would be nice to know things like bolt torque specs and pattern,
plug gap, acceptable cylinder compression etc.
I did a compression check and got 115 front and back. The plug gap should be ok
because the plugs are brand new. The prop is bolted on and is providing a suitable
load. All fuel lines are brand new including the impulse line for the fuel
pump. The impulse line is 6 inches long and was ordered from LEAF specifically
for this purpose. The entire fuel system is brand new this airplane did not
even have a fuel tank when I bought it.
It is an older engine with points ignition.
Thanks every one!!
Ray

I suppose that you have checked to make sure that the nylon cup and the
needle jet is installed correctly?

Ray,
Sorry to hear you're having engine troubles. Recently I had some and got lots
of good advice on things to check. Read through this thread for additional ideas:

I believe you have to take the 2-stroke Rotax class to get the repair manual. All the other manuals (installation, operators, maintenance) can be downloaded from http://www.rotax-owner.com/ under "support>engine manuals".
