I just bought a 77 Comet (250ci 6cyl.) as a project car for my son (15) and I. I'm a relative rookie, and my son is just learning so forgive me if I'm not technical enough. We're having trouble with rough idling. Here's what we've done so far... Replaced spark plugs (black) New Air Filter Oil and Oil Filter change Fuel pump and filter change Dissassembled cleaned and reassembled the carb (not stock) Thinking the next move is a new Distributor Cap and wires, possibly new distributor. Help
If all that does not work. Look in the Tech articles for 2 barrel carb Swap. I did it and it made a world of difference in the idle & power.
EGR Exhaust Gas Recirculation The valve is attach to a spacer plate that is between the Carb and Manifold. The valve could be stuck open and in some cases I have seen this destroy the plate under the carb.
iam not a pro but mine was doin the same thing and a friend said that my carb was worn out but is choke working properly check the donut gaskit i have a 74 comet 250
i'd check for a vaccume leak , probably air getting in betwen the carb and whre it mounts to the engine. you should also get a chilton's manual for the mavericks/comets. lots of pics and easy to follow instrustions for most anything youd need to do. craig selvey had a bunch a while back, i bought one. you should email him see if he has any left Craig@MaverickCorral.com welcome abord
