Have just purchased a seagull 40 plus engine
From 1976 and have been checking everything although it runs well
It has an AMAL carb and want to check if 10/1
Or 25/1 mix.
Apparently the main jet tells you so need to remove and need the tool to do so.
I know radiator keys can be adapted but as I need the service kit would like to buy the kit to include key?.
Have looked at the mine of information on these engines but can anyone advise a good
Supplier

Are you sure it is an AMAL as the 64cc engine of that period had a Villiers, or possibly a Bing (that was about the time when the change to Bing took place). The AMAL was fitted to the 102cc engine used in the Century range. The original from that date would be 10:1 and you need a different needle to run 25:1 which you can get from either SOS or Sheridan Marine. A Bing will run 25:1 without any changes.

Apologies, I forgot that Tranona is also a valuable source of Seagull knowledge.
For an engine that hasn’t been produced for about 25 years Seagulls still seem to have a remarkable following.

I have a 40+ and a Featherweight. Sold my 2.3 Honda. Love Seagulls, simple and reliable. Looking for a late Silver Century long shaft if anyone know of one for sale. I asked John but he no longer sells engines, just parts.

That's OK. I think I may be getting a bit rusty on Seagull, but John (who I have known for years as a fellow MG enthusiast) deals with them every day.

Reminds me I must get my bitza 40plus out of the shed and give it a run!
