HELP PLEASE
hello everyone,
this is my first post on your wonderful forum.
Ok here is the scoop. I have a 1977 ford class c R.V with a 460 installed, and an edelbrock 600cfm . so im classifying it at a one ton van chassis.
for the last year it has been idling so slow it could not stay on without pedal assistance. and when i tried to put it in drive. ive had to be real careful about feathering the gas or it would die. and would take up to a block to get it to 15mph without killing it....well this last weekend i snapped the throttle linkage line so i decided since im going to have to be under the hood anyway might as well replace the plugs and filters on it. well all the installation went well. and when i kicked it over afterwards it was running about 2500 rpm. even with the linkage taken off ,the choke all the way open and the idle screw lower then the bottom setting to where the mechanism isnt even touching. i tried loosening the hold down bolt and plate that holds down the distributer "breakerless" and it will not move "distributor not bolt".
Now can i just turn the dist. cap to change the timing on it . I am at an end of my limited knowledge to mechanics....what can i check to get the idle back to normal. is this distributor one that can be adjusted. and what made the rv do this. any help will be appreciated thanks william

I am going back many years so my memory may be foggy. Have you checked the timing? I had a Colony Park wagon with the 460 and found the timing to be fussy. But that said it sounds like you may need a carb rebuild. There may be a leak in the float or the rubber seats may be dried and cracked for the carb needles. Hope this can help. Also check for cracked or disconnected vacuum lines. One other thing check the fuel evaporator canister filtre. It is on the bottom of the canister and may be covered in gunk which affects the vacuum. It is only a piece of foam.
