RobSedona · August 07, 2015, 10:24:31 AM

We are in so cal victorville area and can only get 1800 rpm after the 8v71 has been running for a few mins . Anyone near here that knows how to adjust this ? and the fast idle does not work.

Thanks Rob

Check the shut down cylinder on top sounds like it is not retracting all the way

RobSedona · August 07, 2015, 10:39:03 AM

OK will check that out

Thanks Rob

If it has set for a long time you may have a injector stuck but the governor and rack setting don't change from setting

OK it has sat 4 years been starting it every month the 1800 rpm started on the way here by barstow Ca coming to work off the 7 grand I had borrow to pay the rip off Shop in Gallop NM with the drop box. also found they did not tighten the drive shaft bolts on the drop box side found that out getting the drive side drum free of the break pads the other day

Took off the stop unit and linkage same 1800 rpm

Will it hurt to drive it with only the 1800 rpm and not have the 2000 rpm it used to have will I lug things that way ? I will be towing a trailer to TX moving there:)

Rob Thanks

Disconnect the throttle linkage on top and move it by hand Rob and see if it changes,yea I remember the drop box deal ? where you at now ? when is the last time you changed fuel filters

I did remove it no change. We are near Victorville CA now and Camp Verde AZ right after But could not make money to pay back the loan there so came here to work it off here where she has her business.

Thanks Rob

How are you reading the rpms with a dash unit or hand held tach with tape ?
