Help Diagnose if blown motor!
My FD seems to be running on a blown motor. I've checked all the wirirng, manifol leaks, changed sparkplugs, wires, checked the coils and found nothing. I checked the compression and it seemed to be alright it pumped up to 120 psi. That just might be one of the chambers. I was told to check the compression holding the release valve and checking the consistency of all the chambers. I'm going to try that today. Do you guys have any other ideas? Please let me know.

Symtoms: Very hard to start, no power, slow rpm climb

 

100% blown motor

What were you doing when it happened?

 

What do you mean 100%? how can you be so sure?? he has not provided enough details for you to say that, It can be a lot of other things.

 

Will it idle?
