Saving Old Seagulls

Does anyone know if Seagulls will run with the fuel needle from such engines as the MK 25c (allen scythe) early Atco two stroke mowers etc. , as these appear to be the same carb , that on their applications ran at anything between 16 and 25/1.

I find it difficult to understand why people would want to run their Seagulls on lower oil ratios.

If it's the smoke, use good synthetic!

Many Of the Seagulls we are using today have run have run very happily for 50 or 60 years on 10:1 ratio of mineral oil.

Lowering the oil/fuel ratio increases the likelyhood of increased bore & bearing wear, lowers the compression ratio & therefore the power.
Where's the positive here?

If you view your Seagull as a disposable item then by all means run it on 20:1, as it's shortened life expectancy won't matter.

You will have to use a vast amount of two stroke oil to exceed the costs of a new piston, rings & main bearings ignoring the gasket set you will need as well & perhaps a conrod.

Can somebody please explain the motivation behind this quest,
I can't see one advantage!

The only advantage I can see is that when the wind is behind me I will not be in my own mobil blue fog bank lol lol lol

I completely agree with you Charles.

I don't get very much smoke at 10:1, and that's using Seagull 2 stroke oil. I do recognise that there's a potential 'Save the Planet' issue that has been brewing for years over issues such as this, but I am far from convinced that running a forty year old motor on less oil for a few hours each year could possibly make any difference.

Sorry I asked.

Andy.

I completely agree with you both. I have a large collection of all makes of antique outboards and reams of books on old engines. I have Peter Hunns antique outboard book and he states that with any antique outboard the fuel/oil mixture should be as the manufacturers suggest. But using modern TCW3 oil to the manufacturers specifications is what it has to be! It is good to see that this is finally being recognised by other knowledgable members of the club.

Andy the last person that called me Knowledgeable, then tried to sell me double glazing or was it 2 front row grandstand seats in Heaven.

I'm sorry to inform you that I have no money & all my windows have been done & the other Charles tells me he has booked me a seat somewhere else!

Didn't need to book it for you old chap - when I enquired it already had your name on it!
