Re: Carb kit help needed
In the short time that I have been maintaining my engine myself as opposed to sending it to a mechanic, I have exclusively used the mercury parts express website.
That site provides you, for your specific serial number, all of the different assemly diagrams for your engine i.e. lower unit assembly, fuel line assembly, carb assembly, reed assembly, power head assembly, crankshaft assembly, transom bracket assembly etc etc etc. For each diagram they number and list every single part, their part number, and how much it would cost to buy mercury genuine parts.
So, IMO, for the most accurate diagrams and parts, without worry that you are looking at the wrong parts, reference the assembly diagrams that the mercury parts website provides. Alternatively, you can order the parts and service manuals from mercury for your particular engine.
