I have not checked the fuel pressure but have to assume it is ok
as from a start I can floorboard the accelerator pedal and everything
is fine up to about 45 mph . . . by then it has max rpm in both 1st
and 2nd gear . . . it is really baffling me as I have been keeping
keeping my vehicles tuned and running since my 1st 1937 DeSoto
all they way through the acquisition of my 1st computer controlled
car when I had to give up . . . . this Chinook is our weekend cabin
on wheels and the 1st conventional carb/no computer vehicle
I have had in years . . . .I am not conversant with PVC and EGR
valves is there a possibility that either or both of them are gunny.
As I mentioned up until the time I let it sit for six months it at all
speeds and throttle settings ran like a champ. Used to rebuild
my own carb's with ZIP kits and the thought has occurred to me
that possibility some of the additives in todays petrol might have
during the period it sat idle gummed up the jets . . . but, she starts
right up and after warm up goes like new until about 40-45 mph.
In the for what it's worth department I'm 80 years old which has
nothing todo with anything other than the fact that I'm no longer
the shade tree mechanic I thought i once wuz . . . .? ? ? ?
