Saving Old Seagulls

Well, I found out what the trouble is. When the air screw is tight down without a washer, it remains 1.3mm above the top of the cap. The washer is also 1.3 mm thick, so when you tighten the screw down, you think that it is tightened by the washer, but it is actually at the end of the thread. I got a...

I boiled the cork in the tap and that worked very well. I did not think to boil a brand new cork washer for the cap. The smaller washer under the air valve is some sort of cardboard looking thing (also new). I will try smoothing the top of the tank inlet, but my friend who also has a seagull says bo...

My fuel cap is black plastic.
When I bought the engine, fuel leaked out so I fitted an new cork washer and the composition washer under the air inlet.
It still leaks!
Any suggestions?

It does not have a sealed gearbox, so perhaps I should use sae 140 oil. With an unsealed box, I cannot see that overfilling and ...

Thanks Oyster. What happened was that my fuel tank cap was leaking, so I bought a new kit for it and to test it, held the engine upside down as I have sometimes done with my Mariner 2hp. I guess that this encouraged a leak that normally would not happen. I am using 90 oil as recommended, but may cha...

I recently bought a 45 featherweight. It is in good condition but cobwebbed over the years in a shed. Got it running fine. I opened the gearbox to find it absolutely dry, so I refilled it, not overflowing! After using the motor, I laid it down on the car boot and about an egg cup full of gearbox oil...
