I am having a problem with my 2 yr old Bronco. Runs fine on flat terrain, but going up slight hill, engine bogs down. If I let off the accelerator , it returns to power. Mechanical moron here, any ideas would be greatly appreciated.
Do not know if this is your model number, check air filter for replacement first, if B&S engine use B&S parts. Post your model number if different & all numbers from engine. Are you sure it is engine struggling or possibly transmission?
I had the same problem, it was the fuel filter. I bought an after market fuel filter. I purchased the correct part number according to the manual and it worked fine. Try changing your fuel filter. But make sure you don't have a cheap one. It would run fine on flat surface. Hope that helps.
