11 hp Briggs or 14 hp twin cylinder opposing

whats your thoughts an 11 hp flat head Briggs or a 14 hp twin opposed Briggs, both are older engines and will be governed/ will be goin on a locked 4 speed Murray 92 ish model / tires 20 plus rear and front. Probably keep factory pulley on front and a 4 inch in the rear. Making for mud and trails. whats your thoughts/ more specifics on my youtube 1darron1 Little Murray Thanks for your thoughts and opinions.

the 11 should be enough power for what you need but the way i look at it is the bigger the better
i used to have a tractor with 25x12.5 mud tires on it and it would do 30mph i never had a problem with lack of power and it has a briggs 11hp

Is the 11hp a cast iron cylinder? I have an 11hp that I'm starting to mess with and it's an aluminum cylinder. So the twin might be a better choice just from a durability standpoint. The twins aren't easy on gas though.

the 11 hp is alluminum

There's no replacement for displacement. The twin will suck more fuel, but the added torque is well worth it IMO.

For power - go with the twin - plus is you wont need to rev the heck out of it if you get stuck either - i ran a 18HP twin on my mod murray - had tons of power for speed. As much as i had it running around, it didnt seem to use a whole lot of gas.

I ran a 10HP briggs on my agway when it was stock ( came with it) - it did okay for power ( when it ran right), just lacked traction ( turf tires) - im planning on using a 11HP briggs on it in its mod form , should be plenty for what riding ill do with it.

Another mod youll want is a gas pedal/hand throttle - itll give tons better throttle response then the stock throttle setup.

Stock tires will be okay for lite stuff, for more traction go with a AG tire or ATV tire .
