I recently purchased this engine and looking for any information on it.

Thanks for your help.

TJDNC

Echo 40cc.
prop---18x10=7350
20x8=7500
22x8=7000
22x10=6000
oil=32:1
3 ring piston.
ballbearings on crankshaft-caged needle on rod.
39.7cc=2.42ci
horspower=3.2@8000rpm
chrome cuylinder
these are the specs that are on the sheet that are in this pic.The ad says $189.00 on prepaid orders,shipping is free.He says to call him after 6PM.Those were the days.I figured i had better add that the ad is old for anyone thinking that theyll just go and order one.

7000rpm with a 22x8 on 40cc that's monster power for sure

Ya i know but i got those numbers off the specs on the right hand side of the sheet.I dont know if those are actual from the guys who sold this(Gibbs Hobby& Reasearch)or its a speculation from a calc program or somthing but by looking at the sheet i dont think PC"S where in evryiones possesion either.Heres the rest of the readings in order,i only put a couple:
weight--6.5lbs
oil mix---32:1
Performance,Top Flight or Zinger prop:
18x10-7350
20x6-8050
20x8-7500
20x10-6500
22x8-7000
22x10-6000
The hobby was located in North Canton,Ohio.(Either its the 3 rings or the elevation.)maybe they modded or ported it somehow.At an oil mix of 32:1 with 3 rings i doubt there was any blowby.
Heres a quote thats in the center bottom of ad:
(after extensive testing, it has become evident to us that under normal conditions you will probably never wear the Kioritz engine out with a model aircraft).

Well lets get that puppy running and see what she does

I agree,i was bidding on a 40cc on ebay but either it went to high in my opinion or i wasnt paying attention when it ended but it went without me.But 2 days later the person that won it showed up here on rcu asking about it.I was hoping to win it and see how it really put out.If those numbers are even close it would be fantastic on a WWI model.My son has a 102 inch DVIII scratch built that was given to him.
