Heres a site to look up part lists & Manuals for briggs motors this would make it around 4hp because the 13 series are 5hp+, from what I know
[color:#FF0000]Briggs manuals click[/color]put in the model number then a dash( - ) then put only the first 4 digits of type number... If the Model number only has 5 digits then you need to add a
0 as the first number... The Type number is important, when looking up a part number it will reference certain variations... the variations are listed under "NOTE" that's where the type number will matter... Hope this is helpful
OH and also the date code comes into it now and then aswell which are the last group called "code" the numbers read: (first 2 digits Year next 2 digits Month next 2 digits are day and the last digits are Factory reference)
