Anyone have a link to a diagram of the dimensions of where the bolt holes are for a Briggs 281707?
I'm playing and would like to know where to drill holes vs eyeballing it.
TIA.

Can you just measure if you have the motor?

I looked there already. Mine is not there but there is a 14hp so I guess it should be the same. Thx.
Side valves & OHV engines have different bolt mounting patterns.
Singles & V twins have different bolt mounting patterns .
MTD , Murray , Noma ( others probably ) use a removable engine mounting plate
so if worse comes to worse you can get one of those from a mower wrecker
I might have one in the graveyard I will have a look latter today.
AFAIK all B&S ride on SV engines have the same mounting centres regardless of their stroke .

Being the bottom of the engine is not flat, I know I would have a template that is off thus drill in the wrong places.
Templates can easily be cut with cardboard and mounted to motor for reassurance it fits before placed

Apart from the crankshaft & oil seal housing the bottom is flat as it has to sit on a flat plate
So cut a 4" hole in the middle and you can use a corn flake packet to make a template .
