as long as the subject has been breached and it is a fact now in many states
and places, has anyone had any type of effect on running or temps on the 912
series, 80 or 100 hp naturally aspirated engines, using the 10% alky they
are forcing upon us? I have a 912 80 hp and would like to know what to
watch for. Seems a 4 cycle should pretty much just burn it. I would think
the new (less than 6 moss) crab and related systems should be alky proof.
Shouldn't have to change the lines either. Anyone having any problem out
there with this stuff -- yet? Ted Cowan, Alabama

Morning Gang:
My 912ULS falls into the bracket for replacing the gears reference a recent
Rotax SB.
Flying down to Lucedale, MS, this morning, 185 miles, to South Mississippi
Light Aircraft, to get the job done. Ronnie Smith will get'er done, and I
hope to fly back to Gantt IAP before dark this evening.
Beautiful day to fly, not a cloud in the sky, and no wind. Only a slight
problem. Was 20F when I got up this morning and barely bumping 23F a couple
hours later. Supposed to get to 60F this afternoon. I have my Chillee Vest
(12VDC) and abundant sunshine for the canopy. With thermal drawers, I
should be able to stay reasonably warm. We shall see. I haven't done any
"real" cold weather flying in a long, long time.
Take care,
john h

If you have a Grainger in your area, they are a good source of 120VAC
fraction HP motor.
They have motor/gearbox combinations with low RPM. Check on their web site.

Ed, have you checked the belt tension? If it's slipping, that could account
for a lot. Also, how is the airpath to the fan inlet?

Don't see what's Kolb-related about a can crusher, but all Kolbers
can find good, cheap motors & many other things at SCIPLUS.COM,
888-724-7587. AKA American Science & Surplus. Fun browsing the
catalog too.

Ed,
My lowest EGT's are 1075 and my highest CHT's are 325. I swing a
Tennessee wood prop that is 66 dia. with a 33 pitch as per the Original
Kolb Co. prescription. I hope you took note that I'm using a different
needle from stock, but more importantly is that I fly (cruise) at a much
lower RPM than most. Usually between 4800 and 5200 RPM. Your choice of
oil is a big factor as to the amount of carbon build up and a very hotly
debated issue here on the list.
Obviously, your flying skills are right up there since you haven't bent
your gear legs yet. Can't say I did as well.

Mike,
If you had bothered to read any of my past postings to the list, you
would have seen that I did spell out what I'm doing. Suggest you go
back and look and while at it, look at more of the long time list
contributors that have posted what they learned from their long
experience. Much can be gained my listening to them.
I have found that an open mouth precludes the functioning of both the
ears and intellect. I try to digest what the guys that have more time
and experience than I do have to say and then choose my own actions.
Too, bad we lost one of those recently due to his disgust with the tone
of the list lately!

Hi Gang:
Got new gears in my gear box.
Despite Arctic weather in the Heart of Dixie this morning, I persevered,
plugged in the Chilli Vest, and flew down to Lucedale, MS.
Ronnie Smith pulled the gearbox, crankshaft gear, swapped out the new gears,
shimmed the gearbox, while I cleaned up the flange faces and got them ready
for a new super duper sealant. In a little more than an hour, I had run up
the engine, checked for leaks, and was headed back to Gantt IAP.
Thought I would be sitting pretty in the sunshine down and back. Wrong!
Was in the shade of the left wing going southwest and right wing heading for
the house.
Flew 380.3 miles in 4.2 hours. Not bad for a big fat ultralight.
