I note a few Irvines coming up occasionally for sale - anyone know exactly when Irvine stopped making engines in the UK? Might get around to buying one at some stage but want to try and get a UK made version. Thanks.

It`s easy to distinguish them, real Irvine has Jett stream carb, and the Osvine has OS carb. The red colour is also different between the two

Thanks for the reply. I assume any Irvine with a Jett Stream carb, that does not have the thermal coating, will have be made in the UK?

I think even the newer Irvines made after OS took over the company still say Made in UK on them. OS standardized a lot of the parts with Irvine, but the engines are still made in the UK. I don't think OS makes the castings for Irvine yet. If they said they were made in Japan, there wouldn't be any reason to have a facility in the UK anymore.

buy any Irvine 39 you can. They are very very pwerfull little engine's. that have the perfect combo of stroke, bore, and crank passage size. with a little work on them 17,600 on a 9x8 in a 10 ounce package..

This guy has a .40 and a .61. They are English made and the .40 is new. http://brucercengines.com/index.html
Love all my Irvines, havent gotten an OSvine yet. Their .36 is a real sweetheart too, Irun one on a .40 size sport plane and it rocks.

The carb is a jetstream, no relation to Jett.

ADG

All - thanks for your responses and the bloke athttp://brucercengines.com/index.htmlseems to have some good stuff. Cheers.

Ican vouch for Bruce, he is good people.

Kostas1

I had an IRVINE 53 ABC Mk2

but made from O.S.

I liked the engine very much & was the first owner.

She performed really well & was a nice,easy to handle & operate sport engine!

Cheers..

Kostas

PS. I had it on a Seagull PC-9 40 ARF.

"I had an IRVINE 53 ABC Mk2"




You no longer have it?

Bummer, I didn't know OS had switched production to Japan for Irvine engines. I had thought they were still assembling or making them in the UK.
Oh well. I learned something new then.
In the pic of the Irvine 53 above, it says "Made in Japan" on the box.

So then the real question is that really a ABC cylinder liner in the engine or is it a ABL cylinder liner inside?
OS doesn't do ABC anymore but uses nickle plating instead of chrome. or is Irvine engines the exception?
If it is really chrome, that would be a huge plus for the Irvine engines to buy versus OS engines.

Another factor is that they no longer  use the jetstream carb.

jeffie8696

It says ABC on the instructions so if it isnt they should get scolded for it.
I wouldnt mind them not having the Jetstream carb as long as the replacement is just as good. That carb looks a lot like the 4D carb on my .46SF and it works fine.

It's an ABN type cyl. I have a copy of the exact same engine as Kostas. It is more a OS than it is a Irvine.

OS changed the bore and stroke from the original Irvines, probably to use whatever OS parts that suited. That means a different crankshaft, piston, wrist pin, cylinder head, possibly conrod, the liner is ABN instead of ABC, the carb is OS. The paint seems to be the same though .

earlwb

Well that really sucks, they use ABC stickers and ABC printing in the instructions but the engines really have ABN sleeves.
I hate it when  that happens. Especially with all the venders using the same ABC letters in their engine ads too.

Kostas1

Yes,indeed,

O.S. changed some of the internal parts of the engine
and maybe they replaced the originals with some parts of their own product line!
I guess they wanted to minimize production costs.

I said *had* because some time ago i sold both airplane+engine.

I never had or seen an ACTUAL Irvine performing,
but the O.S. clone i had performed rather well for the money spent
& i was ,at the end of the day, happy with my purchase!

Gentlemen, I haveaquestion.Fitsaconrodfrom theASP46inIrvine46?

I had obtained a old Irvine .61 from another fellow, and I found that he didn't exactly treat the engine all that well. Apparently he had crashed it at once time or another and put a old ASP carb on it too. Anyway, the engine had no compression at all, but the cylinder looked really good, almost like low time on the engine, where it still had the hone crosshatch marks on the cylinder. Plus the bearings didn't feel smooth either.
I had a devil of a time getting the head off, apparently someone had overtightened the screws so much so that three of screw heads stripped out on me, so I couldn't use a allen wrench on them. I had to use a drill press and drill the heads off the screws, remove the head and then use a small vice grip pliers to unscrew the stubs. of course then the rod didn't want to come off the crankshaft either. But after oiling, heating it up a few times, and fiddling with it for a long time, it popped off. Then I found that the dykes piston ring was stuck on the piston tightly. I looked at it with a jeweler's loupe and couldn't find the ring ends or gap. Eventually, I started gently tapping on the ring around the circumference and suddenly a ring tip popped out so I could peel it off. With the jewlers loupe the ring actually looked pretty rough and pitted around its outer edge. I then used the old ring to clean out the piston ring groove real good.
So now I am waiting on some new crankshaft bearings so I can put it back together. I'll need to find another carb, preferably a Irvine carb for it as I don't think the old ASP carb is really any good. But one doesn't know until they try it out though. I might have to stick a Perry carb on it.
Fun stuff fiddling around with a engine and trying to save it to use again.

Mr Cox

I have seen one of the red Irvines at our field, it was low on power and made bubbles around the head when it was running so there may be a production problem there...

dieselbloke

More likely a ham fisted user problem!

I have nine Irvines from 0.75cc and 1.3 cc diesels to the .25 ci red glows and certainly head leakage isn't a problem in any of them. One can't account for the incompetence of the consumer can one Mr Cox?

TimBle

I have a Irvine 53 Mk I with the Jetstream carb.
Obtained it 2nd hand. Runs ok but previous owner said it had 6 flights on it. Lying bas***d.
Its pretty low on power, barely better than a .46.
stuck with it but sure it could be a great little engine when I rebuild it.

Mr Cox

Well those are not the latest batch from OS as far as I know?
I really like the Irvine 20D myself, but that is also from the original manufacturing and true ABC (one should not have to use the word "true" but I don't know how to clairfy this in any other way).
