Technical identify My Engine number

[ClassicFiat500]

Hi all is it possible someone can identify my engine number with the year & also what g/box it is linked to?
The top row 123 A1 000 then underneath looks like 9 but not sure then 677264
I need to buy a new rocker gasket not sure which one to go for cork or whatever is best & should I use gasket seal?

Your engine number tells us that it is a 652cc '126'engine. As far I am aware, the chassis number is traceable but not the engine number. If your number IS starting with a '9'that is a very late engine as the 2 652cc engines I have both start with a '4' (47##### + 46#####).
As for the rocker cover gasket they are the same for either engine, but I woud go for the 'rubberoid' gasket rather than the cork variety. They require NO gasket seal---just make sure that the rocker cover is sitting down well and clear of any shrouding (they often sit VERY close to the thermostat-housing shroud)

You need to put a clamp on the fuel lines--and NO filter between the pump and the carb

The engine type on your pictures is 126 A1.000, not 123 A1 000.

Post 6 in this thread https://www.fiatforum.com/500-classic/285020-motor-salad-need-help-identifying.html suggest that engine type 126 A1.00 was used between 1978 and 1979.

The engine number on your pictures is 9677264.

And a Fiat produced engine and not a polish one.

Blatantly stolen information from a thread further down the board ?
