    Had a Saito 91 in mine a few years ago at 560gms incl silencer is lighter than both of those.... Went like stink on a 13x7 prop.

    Motor had been run on MT Dynaglo 5% for the last 10 years 8% Synthetic 2% castor.

    Two for me, with a Sullivan crap trap filter.

    Have been using the slow cooker (crock pot) with concentrated Ethylene Glycol antifreeze for a couple of years now with great success, it does not send the alloy parts dark grey and of course is non abrasive. Just an old toothbrush to help move the crud and a good rinse and dry afterwards. Have attached before and after photos of a Saito silencer I did last week..... 7 hours in the pot and good scrub, less burnt on parts will clean in two or three hours, such as heads and crankcases.

    Have been running my Saitos on 10% oil and 5% nitro (MT Dynaglo 5) for about the last 20 years with no probs, they run sweet and clean.

    From what I can gather that model will come out around 6-7lbs auw, in which case a 40 Surpass is very marginal to say the least, would have thought you are going to need at least 56 - 82 size four stroke.

    No that does not look like an Enya 4c plug, I have about 4 of them, they seem to be as good as the OS type F. they look like this...

    Yep try it outside, my tacho does the same under florescent lights

    Right, it perhaps might be a good idea to block the rear one off, the reason for having the breather at the front is it will force oil through the caged rear bearing and into the cam gear area on it's way out. Having the second breather on the back plate will just allow the oil to take the path off least resistance, probably through that rear vent and not directing the lube to the front of the motor. There are a lot of Saitos with the rear vent only and they all run fine, however the majority of later engines have the front vent set up for the above reasons.

    No it's a 62A, the same as Glenn's with the older type cam housing.
  11. Martin Arnold 1
    And the crank case breather ?
  12. Martin Arnold 1
    Pretty sure that is a 62A, the B has a different crank case like this below. Is that a second crank case breather on the rear cover ?
  13. Martin Arnold 1
    The 62A and B have a metal back plate, it was the early 72A and 82A that had the plastic back plate the later B's were metal. The main difference between the 62 A & B is the cam housing the A has the original lower style where as the B has the higher profile one that the cam drops into.

    Are you talking about the gas powered live afterburners ? have seen a few vids of them on Youtube.
  15. Martin Arnold 1
    All saito singles are pretty much the same, here is an 82 rod, having a mark on both sides would just confuse things...... Simple dot faces forward.
  16. Martin Arnold 1
    No Saito rods have a dimple that should face forward.

    "Martin, is your photo of another engine with this issue?" Yes Jon, that is a third engine, coincidentally he bought it BNIB last week. Having seen Fin's polishing work it does not seem to be an issue, still not a pretty thing to see on a new Saito though.
  18. Martin Arnold 1
    The rods are out of stock at hobbyplastic !
  19. Martin Arnold 1
    Looks more like a casting fault on that shot, my pals is the same !!
  20. Martin Arnold 1
    Have to say looks like a crack to me, obviously the motor had not run, the assembly grease is undisturbed on the first photo. Still don't understand how they became cracked, I have two 62's but they are both the older "A" version. Have sent a link to this to a pal of mine who has just bought a BNIB 62b will see if I can get him to drop the back plate off his and have a look.
  21. Martin Arnold 1
    Think you need to take one of rods out to have a closer look.
  22. Martin Arnold 1
    Are you saying both engines have a cracked con rod ? Amazing that should get through quality control at Saito !!
  23. Martin Arnold 1
    Spot on with the 12x6 on a 62 for a trainer, have to say Master aren't my favorite make, I often use a Graupner Super 12x6 on my 56/62 Saitos.
  24. Martin Arnold 1
    Looks good Aidan, glad to see you went with the saito62, what prop do you have on it ?
  25. Martin Arnold 1
    I was interested in it for the very reason it may have a lower oil content than most fuels, but still can't find out !!!
