My 1282 has a bad vibration, upon inspection I found the balance gears were removed. I set valves and carb with a small amount of improvement. It does run okay and doesn't burn oil but thinking of repowering it as I have a 2160 with a great running briggs vanguard 16hp. I didn't really want to immobilize the 2160 but it is an option. My question is leave it original and add a balancing plate to the crank or just swap the engine out? What is another engine possibility for the 1282?
