the trail tractor

i have a 2007 chraftsman that origonally came with a 21 or 22 hp briggs v-twin ohv sence i have done 2 engine swaps and i found the engine i like i went to a 17 hp briggs and dint like the way it ran so i went to the old kohler commant which is a 14 horse...runs great just needs some carb work...put some new tires on it i had laying around (still regualr lawnmower tires but on the trail they work great) the steering arm that connect the 2 tires i have custom made out of forged steel which was a pain in my ass...currently do not have ANY belt keepers but its been runing like that for 2 years now and have yet to have a problem but its also still in the build stage....so far thats about all ive done to it beside just change small little parts...and im still running stock transmission and i will be till i break it

By stock trans you mean hydro?

Also, what was wrong with the briggs? i love briggs singles and haven't heard too much bad from the v twins

by stock i mean stock 6 speed manual and guessing its old age with the engine its a erly to late 70's
but i do have a late 90's kohler on it now

I don't think V twins were around in the 70s. In the 70s they were putting in little 8-11hp Briggs, then in the 80s opposed twins came round.

no it was a single cylender from the 70s my vtwin was the origonal on the 2007 craftsman im building

okay i have a 14 horse kohler should i put a 15 or 16 horse kohler carb on the the engine for more power and should i install a fuil pump??? also how would i mount the new pully (for now im going with a 6.5 inch instead of my 9 inch but i wanna keep the 9 inch on it being it has the teeth for the trans) i know if i go smaller i would have to instal a new tentioner pully and i wanna be able to switch between the 2 pullys for different things i might be doing...and should i snorkle it or no??? i have an origonal exhaust moddified to fit on the tractor (cut it and rewelded it so it would fit the angle) i cut the muffler around the pipe off and left the origonal pipe there is that okay or should i remodify it?

I can't help with a whole lot there, but I believe your engine already has a fuel pump. If its the same engine i have it does anyway. I don't think a new carb will do much for it if the governor is still intact. Bigger carbs actually hurt low end performance. They only help higher in the rpm range.

now i have the origonal tractor brakes (for a craftsman lt1000) and i want to build a cheap bettwr brake system for it possibly something from a bicycle but idk how todo that tho and i want to spend as least as i can...rn i have 40 dollers in it (bout the engine cuz the dude thought it was locked up but only issue was the belt got burnt and wouldnt let the engine spin)...i know how to do the throttle for the foot and all and i know how to do the welding for the handle and brake handle
