Just a thought -

How do you know what series my engine is ? and can I check it for myself online? I guess that you went by my engine number that I quoted as being BB 80680 U 688355 Y.
The link to the .pdf manuals is for the 4.107, 4.108, 4.99
Are these related to my 504-2T engine ?
Sorry if this is a dumb question but I am not familiar with the numbering and series etc. The numbers look quite different to me !
Thanks for advice
