    I have put to one side for the moment. I have some better fuel on the way and hope to continue in due course. Meanwhile, I am making a test engine of 0.3cc and hope to gradually scale down to 0.1 . Hopefully I may learn what the problem is 😬

    Hi again Ken, Thanks for the info. With the revised spraybar which passes through the venturi I have 0.9 sq mm area so much better than the standard setup. The engine draws fuel readily when choking the carb and I am still looking to find better fuel. I have put this model aside awhile and am...

    All my engines are mounted and on display in a cabinet :)

    Attempting Gordon Nano

    Despite still being a non-runner, I decided to anodise the cylinder and spinner anyway. Its surprising just how small this engine is when compared to the Clanford Clan.

    Hi Ian, That's very kind of you. I am near Coalville in Leicestershire. Ether to boost my fuel or high ether fuel mix is what I need to confirm if this darn engine will run but I only need a very small amount. I have tried extraction from starter fluid but I am not convinced what I have...

    I didn't fancy the acid route so tried this:

    Attempting Gordon Nano

    There is a John Deere starting fluid over here but it has a different part code to the 80% version you can get in US and I cannot find an MSDS note for it which covers the Ether percentage so it may be a lower spec fluid like our auto versions which vary from 10 to 40% if you are lucky. I tried...

    Hi Tim, Yes, you are correct. I had several pops during driving with my safe starter motor and since then I have discovered the transfer ports are only just being exposed. I have now made a new cylinder which certainly allows scavenging and I have paid attention to the crankcase seals at...

    Jens, You can add and adjust the balance ratio as necessary, its just a case of math. :) Rich

    That's the problem... buying it. Ether is a controlled chemical and is very difficult to buy here in UK (and most of western world). A previous post linked to an Ebay shop offer but £40 for 250ml is way too steep. Even buying fuel ready mixed is a problem here. You buy glow fuel no problem but...

    Attempting Gordon Nano

    Hi Rich, I too have resorted to using my starter with a rubber tube connected which slips if there is lockup but on this last re-build I am holding back until I have better fuel, one way or another. I have almost finished the revised spraybar which is rather 'twee' being the 0.070" diameter you...

    Attempting Gordon Nano

    Thanks Jens, It does appear that in one way or another I need more Ether than I have in the present fuel so the search is on for either better fuel, Ether or Ether via starting fluid. The John Deere fluid looks ideal at 80% but difficult to get here. I will endeavour to find a solutio, Many...

    Thanks for that. I am suspicious of my jet to needle alignment plus I also made the screw slightly short so I was going to re-make the parts. Perhaps I will try the conventional spraybar solution you suggest. Can you tell me if you used high Ether percentage fuel? If I really need that then its...

    Hi Ken, Well, I swear for starting this too. I am getting a bit bored with unsuccessful results so far but I will stick at it a while yet! You obviously have great experience on small engines, any guidance would be gratefully received. The Weevil looks cute, very similar to the Clan in format...

    Thanks Ken, I will double check everything as advised. The Nano doesn't seem to be as easy to coax as the "Clan" that's for sure. Rich

    My thoughts exactly! Southern Modelcraft do 500ml for £7 Southern Modelcraft I am hoping a show comes up this year to be able to get either high ether fuel or the Ether itself.

    Just a quick update. Thanks to all with their encouragement and helpful hints. I am still progressing with the re-lapped cylinder and new piston but after installing the con-rod and actually achieving a press fit of the wrist pin I found the piston still needed a little lapping and I...

    Hi, thanks for your reply. I don't think this is a problem and I refer you to RKlopp's comments earlier about my concerns with a small gouge from the crank drilling operation and his comments about loose carburettors etc, and he has built three engines and did get them running (jealous :) ) This...

    Attempting Gordon Nano

    Hi Peter, The mix I am using is 30% Ether, 30% Castor, 38% Kerosene and 2% amyl nitrate. I would have preferred 35% Ether mix but getting hold of it is tricky as most suppliers will only allow collection and none are near. It's also a stupid price compared to that at shows from the dealer...

    Attempting Gordon Nano

    Well, the engine is complete but alas no sounds of life at all :-( I tried flicking, RKlopps method with a rubber tube on the spinner which is much easier but still not a pop. I even resorted to using a starter but coupled with rubber tubing which slips if hydraulic lock occurs. This gave a...
