Hello, my name is ***** ***** I am going to assist you with this.

Yes, this unit has a compression release system. There is a centripetal flyweight mounted to the crankshaft inside the crankcase.

The most common cause of a bad decompression system is a worn or disconnected return spring on the flyweight.

OK I WILL CHECK IT OUT, I WOULD REALLY RATHER COMMUNICATE BY PHONE. MAYBE JUST ANSWER IS NOT FOR ME. CAN U GET TO SPRING WITHOUT MAJOR DISASSEMBLY ?
Customer: replied 18 days ago.
I WILL GLADLY PAY 26.00 FOR PHONE COMMUNICATIONS INSTEAD OF EMAIL.
Expert:  Hank F. replied 18 days ago.

The spring is located inside the engine block. The block must be separated to get to the release mechanism. It is not going to be an easy job.

The genset would need to be removed from the coach and be completely disassembled to open the crankcase.

Hey Hank, I have accepted your phone offer. However, there is an error message that says, "Sorry, the Technician is unable to call you right now, but is still available for this online conversation. You have not been charged for the phone call."

You will need to contact Customer Service to have that issue taken care of.
