If a brake is binding try driving in a straight line on tarmac, lightly grip the steering wheel and brake firmly. The gator will 'pull' toward the binding brake. So pulling left is a left side brake and pulling to the right is a right side brake. Another test is to chock a wheel and safely jack up each wheel enough to clear the ground and turn each wheel by hand. A binding wheel will feel tighter or won't turn at all.

How to test and replace a fuel pump relay. The principles shown here apply to most vehicles. However, it's best to check your vehicle's repair manual for testing parameters. This specific vehicle is a '97 Nissan Maxima.

There are a lot of you tube videos on this unit. See if any apply. It is a specialty machine and John Deere is proprietary.

Sounds like your float is stuck. Pull that carb off and clean it. Berryman's carb cleaner is one that works well. Clean the float needle and check the surface. Use aluminium cleaner/polish like mothers on a cotton swab and clean the float needle seat. It will shine up like new. Check your float height before reassembly. I do these all the time and don't need to but parts.

Try a reboot. Disconnect the ground lead from the battery for 15 seconds, then reconnect and try again.

Look in the owners manual

YOU DONT! Factory specs are need to test and set it!First off what is the problem you are having????All the TPS does is switch from one timing curve to the other on the cdi, and is also connected to the fuel management computer to tell it when to increase fuel delivery.If you are having running problems start with old fuel, fuel pump pressure, and last if you have modified the airbox or exhaust in any way it will run like crap! On fuel injection you have to get a tunable fuel management computer when increasing air-flow or exhaust flow. The fuel injection is set from the factory based on the OEM parameters.How many hours/ miles on your unit?Have the valves been adjusted if it has over 200 hours of use?are there any codes being flashed on display when key is turned to on position but not running?

not adjustable.

too heavy a load

check your gas tank screw on cap......if there is a breather hose coming out of the cap....make sure the hose is not kinked thus causing a vapor lock in the tank
