Saving Old Seagulls

Hi all

I am trying to send a PM to one of our members but the message seems to just sit in the “outbox”, and not move into the “sent”box after hitting submit. Am I missing a step?

Hi all

I would like to pick up from my earlier post here and rename it to something more applicable:

Over the past few weeks I have been soaking all nuts and bolts in penetrating fluid, and having applied lots of heat I am happy to ...

The cylinder head is not water cooled, only around the sides of the cylinder, so yes, the cylinder heads will get hot.

If you hadn't mentioned that your father had installed the recoil start, I would have thought it was an optional extra that I wasn't aware of and had been fitted at the factory ...

I’ve now had the motor running in a drum. Initially it only ran on one cylinder, so I replaced the old Champion 8COM spark plugs with a new set of D16’s, set the points, and it started second pull and ran smoothly.

Can somebody please suggest the basic / useful sizes I ...

Thanks Charles
So as mentioned above, this OP would most likely have had the “British Seagull” flying gull tank transfer, rather than the “Marston Seagull” logo?

Thank you all for the responses. Yes, the project will be approached with caution now that I know the significance of what I’ve got.
The jubilee clips holding the tank wound undone surprisingly easily after soaking in CRC overnight. They are now soaking in a parts cleaning / degreasing solution ...

Hi all.
New here, and have what I believe is a relatively early 102 (S/N OP613) which I was given by a neighbour who was sorting through an estate. My nine year old son and I are currently giving it a tidy up. I doubt that it had been run for many years prior to us receiving it, but we set about ...
