That old Seagull engine you have, can it be fixed when its seized solid ?

This was one of two requests for Seagull information and on the same day.

Dear Roy, Stubbornly I cling to this old British Seagull Motor I have which does not work.  The most likely explanation is that the magnets for generating a spark are too worn.  But we don't know that.  I could not figure out how to take the top off in order to get at the magnet. 

 Is there any kind of manual or other instructions for disassembling the motor?

 All the best,

Here is my reply and as yet not replied to.
Cort,

Thanks on your mail!

Please do not take the flywheel off, this is not recomended, you can take the top cover to service the points though.

The points and spark plug gaps are important of course, so start with them, if there is no spark at all, try a power drill to the

Flywheel and spin it up, this will normally re generate a magnet and thats it done?







May I have a picture of your motor  and the engine number please.
Johns site will date your motor by the way.

The other Seagull engine was brought to me for a look over, all in all it was a very good buy and with just one part missing, which was the plastic bracket that holds the rear drive tube in place, this needs to be there!

I advised the new owner to take the parts of like fuel pipe and carb, clean them and the fuel tank, plus the two in line filters before trying to start it. The engine is now a runner and we got a phone call asking how to stop it!

That is easy, just place your hand over the air intake.


 The engine number dates this as a 1975 forty plus motor and with a 2 to 3 HP output.


This motor is in fine condition for its age. The forty plus will run on a 20:1 fuel petrol mix, you may need a new carburettor needle to be able to do this.

How do you stop a Seagull?  just place your hand over the air intake.

How easy is that!

Have uploaded a video showing how to free up a seized seagull 40 motor, along with stripping down and replacing other parts. Hope this is of use to someone. Please feel free to share it as I am sure it will encourage more people to buy more spares and save a few more from the scrap heap.

Kind regards    Andrew
