Saving Old Seagulls

Kean leaking occur some times when the contact of the ferules and the fuel tap or carb is not perfect. When that happens I add some teflon tape and the problem is solved.

If you apply too much power you may distort the ferules as it is soft brass.

The original fuel tubes fitted to Marstons, SDs, 1940s 102s, and the FV/FVP engines used soldered on joints, rather than compression olives. These fittings are available.

I will try a bit of teflon tape and see how that goes first. If no go i will go and see the fitters at work and get them to make one up. As for the hot starting dramas im having. I checked the magnets on the flywheel and one side does not magnetize. Is this normal.

You checked yeh?

Maybe stay shy of ignition for a bit.

Nice job of it by the way..............

When i fitted the cases back together i used a bead RTV red silastic, So im hoping thats a good enough seal. Is there any way to check to see if its leaking or not.

Just walk outside and had a look at all the studs. The top 2 studs that hold the cyl to the crankcases (under the ignition plate) were loose, Thanks for that C I I will put it back in the test tank tomorrow and try it out. Hope thats was the problem.

Could well be .....I use good old red Hermetite
never had a problem.

All the RTV I use, claims to be fuel proof.

If you use the wrong profile olive/ferrule in the fuel tap or a retaining nut that doesn't suit whatever you've got on the end of the fuel pipe, it would be a very big ask, expecting it to be fuel tight!

Thats fixed the problem. I mounted it in the tank today and fired her up, Ran it for 5mins and shut it down. Left it sitting for a couple of minutes and fired her up again on the 1st pull and part throttle . Thanks again C-I, Your the Man and old girls rule. We may have to change your name to C S I Bloody air leaks.

Wet test. Very happy with it today, Time to go out on the water now.

You were close to bend the con rod!
But it was certainly a rough test!

If water was to get in it would just stop. I got swamped by a Jet-ski one day out on the water with a 40-plus on the back and no storm cowl. All that happend was it just stalled. It started back up after 2 pulls. There a pretty tough motor. Ask chris how many times he has drenched his seagulls out on the water. Im confident that it can handle a big trip out on the river now.

What hes saying is that water is incompressible unlike air
if the cylinder is full of water it could bend the conrod
sometimes happens to marine diesels on start-up if water has filled up the cylinder
them inlet cowls are good aint they

Oh, I see. I would be afraid of trying something similar!
