Irvine Engines

Getting ready to install/run my Irvine .36 Stunt C/L modified by Big Jim into my new way-too heavy Nobler. Went to a website that sells Irvine to look for any tips on oil content/break in. Didn't find anything useful, but did find a link where a company will supply an adjustable C/L venturi for any size Irvine and said no timing changes made because engines are conservatively timed,anyway. Also went to a "monthly offer" link which has a money conversion chart because these engines are all listed in British pounds. Prices seem to be very low for the engines advertised. Don't know if these are any good yet, but the links are:

for the engines.

for the venturis, and (at the very bottom)

http://www.justengines.unseen.org/monthly.htm

for the conversion chart.
Just FYI

I have 2 of the Irvine 36 motors. One currently is with Leonard. At any rate the one that I have here and used didn't impress me with it's manners. Yes it is a delightful handling motor to start, but I never had one run where it didn't run away. that motor had head changes, different fuel, plugs,props, venturi changes. its nice, runs good but for me without a conversion by someone with a lot more time then me it left a lot to be desired.
I also know that Peabody had one here for sale in the classifieds and he had a similar tale of woe, and he had had some work done to his motor. I know that he disposed of the motor at a loss.
I don't know what Leonard would do to this thing, assuming that he wanted to put the time in to it when there are so many other motors out there that seem to work so much better.
Dont take this as a condemnation of the motor on my part. It's just that at my level of experience it wasn't the motor for me. so it sits in it's box waiting for a new lease on life. Who knows, are you up to the challange Leonard.

If you really want the scoop on how to run Irvine engines and how to set them up you might want to e-mail Barry Robinson in the UK. Barry was using an Irvine 36 in a large take-apart plane he used in Shanghai in 94. I looked it over quite well at the time because I was impressed with the performance in an airframe that was large for the engine. Don't really remember much about how he set it up.

For the sake of curiosity, please define "way-too heavy".
