1980 bj40 24v canadian spec
as part of random maintenance, i replaced the diaphragm.
start the truck up and now way more black smoke,
hmmm, removed everything to ensure that the housing/spring/diaphragm,spacers were correct and seated well.
start the truck up again and way more black smoke again??
The old diaphragm was not torn.
Possible it was stretched and the PO turned up the fuel?, and now that a new one is in place i need to turn down the fuel?
Any thoughts on this subject are appreciated.
