Motor running fast - Qianjiang Motorcycles

Motor problem. Brushes inside wearing out. .. Sadly they dont make things as reliable as as back then... I would just use it until it quits...

remove and have the carburettor serviced as what that indicates is blockages in the main jets and circuits
could be corrosion from, or water in the fuel

you might need a new switch

A 2000 Isuzu would have fuel injection not a carb, so no choke is used.
You would need to get the computer checked for trouble codes, I would suspect a huge vac leak is the cause of the fast idle.

Most of the time when the motor is running to fast it's the pinch roller not doing its job it may need cleaned.

Yes, you need to replace the fan motor. Here is a link to the part you need.

Yes, this is normal what is going on is that your oil pump is not spinning as fast. your pump runs off the motor and the fast the motor goes ( rmp ) the fast the pump spins and pumps. the motor dose not need as much at low rmp as high rpm. look up toroidal oil pump.

Slow is the same speed as 'mist'. Mist is when you twist the control arm backwards to induce a single swipe. If you hold it, you will run the wipers in low speed. Fast is faster than that. Probably by 30% or more.

Turn the wipers on high speed. Wiggle the connector at the wiper motor. If the wipers run sporadically as you wiggle the connector, you either have a bad connector or a bad circuit board on the wiper motor.

you will have to replace the condensor fan motor

Set machine to wind the bobbin to check for how fast the machine will run. I believe it will run fast or slow according to how hard you depress the foot control. If it runs fast and slow you have a problem in the machine. Most likely the machine, if turned by hand, is hard to turn and it needs to be professionally serviced. before it is ruined.
