Engine Doctor Posted October 8, 2022 Share Posted October 8, 2022 If Weston cant help with piston ring try "Gaviscool" on ebay . He supplies piston rings for most if not ALL model engines . Prices are good and rings are excellent quality. RCV 58 size is about £12 inc post to UK but post France may be different . Cant see RCV listed on his site but worth a call. I use his rings as its easier ,quicker and cheaper than making my own . I have no connection with the seller just a very happy customer.

Paul De Tourtoulon Posted October 8, 2022 Share Posted October 8, 2022 Thanks, I have had a few rings from him including 4 for my 4 Saito .45 Specials, they are better than the original ones as are his OS ones, he replied that he needed the piston and cylinder to make one up, the problem is the post and it's rates,, Surprise, The original head has a cardboard gasket not very good to dissipate the heat, so I refaced and drilled Irvine 53 head and fitted it without a gasket and flicked it over without the plug hole open, big mistake it was like a flooded 2 stroke a geyser of fuel spouted out, so I put a plug in it and ran it, a pleasant surprise, 9.350rpm and an idle at 4.000rpm, but on the safe side 4.250rpm. I will ring Weston hoping that they might send me a new ring. Quote Link to comment Share on other sites More sharing options...

Paul De Tourtoulon Posted October 9, 2022 Share Posted October 9, 2022 Sitting around 'thinking' and a bit of measuring has made me come to the conclusion that the gain in power and idle stability has come from less compression loss, not the ring but blow back between the turning cylinder and the aluminium cylinder block, I took the head off and placed my palm over the head and sure enough a lot of blow back, there is 3.5mm spacing from the original head and gasket and only 1mm with my Irvine one so I will fill in the concave crown on the Irvine head and fill in the plug thread at the same time then turn it down to reduce the 1mm spacing and see what that does. A bit crowded but you can see it all in the one picture,,, Quote Link to comment Share on other sites More sharing options...

Paul De Tourtoulon Posted October 9, 2022 Share Posted October 9, 2022 Both but with the usual 004417 etc from France it took me around 5 times to get one of them ringing, and no answer phone, I also filled in an order form on their site but no answer, as did both of my mail enquiries,,, Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted October 10, 2022 Share Posted October 10, 2022 (edited) I finally got through to the boss, nice chap, he gets an idle of 2.600 rpm with them, no secretary this morning so wait and see,,, 50rpm up on the top end but little change in the idle, so waiting for a piston ring.

Don Fry Posted October 12, 2022 Share Posted October 12, 2022 Actually, 2 euros is right cheap. Try the Post office and their handling fee I think. I keep on grinding on. The UK has left a customs union. For better or worse there is a customs check, and it costs. Do you want me to pay it for you. The ring, however, is good value. I remember watching my father making them, skill and work. translation, there is a fee, pay online, you get a QR code, show code to postie, cost 2 euro. Ignore this, pay postie 8 euro on the door. Mine, will bring the change round next day. But he’s a nice bloke. Dog likes him, a telling thing. Quote Link to comment Share on other sites More sharing options...
Manish Chandrayan Posted October 12, 2022 Share Posted October 12, 2022 2 Euros for a 10 Euro merchandise isn't much when I compare to what I have to pay here to the GoI towards import duties and Goods and service tax when I import my models and parts. And shipping from UK/Europe/US to a India is not for faint hearted😀 Quote Link to comment Share on other sites More sharing options...

Don Fry Posted October 13, 2022 Share Posted October 13, 2022 Paul, the two Euros is the fee. The ring will cost in total, £10, postage, €2. That is less than the cost of a bottle of caster oil big enough to shift a bowel movement. Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted October 13, 2022 Share Posted October 13, 2022 ring 10€ post 8€ western UK sent me the invoice, 'Piston ring' £18, the 2€ is for paperwork fees' my castor oil goes in my engines which seems to give unnecessary bowel movement to one or two members on the forum,,,😆 2 Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted October 18, 2022 Share Posted October 18, 2022 Got my piston ring this afternoon, so what did I get,,,, The engine didn't like my antique Top Flight 12 x 6 so back on with the 11 x 6 😉, three different carburettors were used, on the left the Irvine .53 which is an 8mm carb, peaked at 9.300 rpm, the right hand one which came with the engine which is a 7.5mm carb 9.000rpm and the one installed which is some sort of rubbish carb like MDS is also a 8mm inlet and gave me 9.800 rpm, also if I left the plug ( new OS 'F' ) connected the engine knocked, not liking it at all and of no benefit to the idle which was more or less as before, at 4.000 rpm it died out so 4.500 was nice and stable, the compression was better the old ring is in the front of the picture. So what next a plane ?, I do have a Robbe Do-it with an OS in it also it will give me something to do and get used to the engine. Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted October 18, 2022 Share Posted October 18, 2022 Forgot total cost for my £10 piston ring, 28€🤢 Thanks to Brexit !, a local lad was getting 4 lasers for his 4 meter Lancaster, but now settling for Saito's, Lasers with Brexit for him is too much hassle.

J D 8 Posted October 27, 2022 Share Posted October 27, 2022 So which carb did you use? RCV never going to match a Rossie but likely use less juice. Energy management comes into your fling now. Quote Link to comment Share on other sites More sharing options...
