Saving Old Seagulls

Thanks for that, I'll check that out too.
My piston slide does seem like a pretty snug fit though, no excessive slop in it's movement up and down.

The spark at the points was observed in the dark as I spun the engine using a power drill, and the spark at the plug was considerably brighter than that at the points. Both seemed the appropriate brightness to me but I have no way of quantifying them. All I know is that the motor starts within one o...

The coil resistance measures as specified at 4600 ohms, the HT lead is good, the plug is new, there is an incredible bright blue-white spark at both the points and the plug, and after getting the fuel mix right, it starts immediately and runs perfectly, even at a really slow idle, so I can't see tha...

CI- I haven't opened it up again and taken the center jet out as it's running so well now I hate to disturb it to look inside again. How thick is that washer? Could that 1mm height difference, if it's missing, have that much of an effect? Turning the screw in and lowering the needle should have made...

From looking at the center tube when I gently hammered it out, I don't think this was ever removed or even touched before, so that's probably not an issue. I assume the main bearing is fine because I could easily spin the engine by hand without the plug in and there's no resistance or scraping noise...

Charles - I followed your suggestion and replaced the new needle I got from John at SOS, meant to replace my #3 to allow running on 25:1 mix. It's supposed to be a #2 but there was no number stamped on the needle he sent me, altho it was in a packet said for the 25:1 conversion. With that needle he ...

I didn't notice one fall out when I took the center piece out to clean the side hole air vent, so it must still be in there. But I may take it apart again to take a look just to be sure.

Thanks. I was actually thinking of trying that, putting the old needle back in, but I was wondering what that would do to the engine which was designed for a 10:1 mixture. What does the change in needle do, make it a richer mixture? More fuel delivery? Why did BS originally spec this out as a 10:1 a...

Right now there is no filter inside the fuel tank. I haven't replaced that yet and is the only part left I need to get. The banjo filter is clean, there is free flow of fuel into the bowl, the tickler works, and you know how long these things can run even with the petcock turned off just on the fuel...

High guys, Marc here, from the western side of the pond, longtime Seagull owner, looking for a little helpful advice. I have 2 Seagulls, an EFPC 2222AA0 from Jan'80 that I have owned since its' birth, and an FPL1689CC6 from March '76., both of which I have recently resurrected from the dead. Both of...
