Running Rich
First off Thanks for the help in the past for those that rember me from earlier this fall. For those that dont rember my noob questions. Ive recently pulled a truck out of a tree claim in a farm yard and have been trying to bring some life back into it. So here comes the new question.
I have an 86 Ford f-250 with the 460. This fall I put a carb kit in it The kit came with the wrong gasket for the intake so i had a vac leak for the cross over. Sounded like an old grain truck but idle'd well and ran fine. Now i finally got around to changing that gasket this weekend ( i dont drive it much as its still a work in progess) Anyhow the vac leak is gone and now im running really rich. Just walking though my exhaust makes you smell like you spilt gas on you.
A friend and i looked around for a mixture screw but were not able to find it. any help there would be great. I also have no idea how old the spark plugs are so im going to change them to. its dumping so much gas its almost like having a dead cylinder. Just seems odd since it started right after chaning that gasket.

Thanks for the photo explains why i couldnt find them and yeah my plugs are filled... I heard you could drill them out but it looks like a major problem to adjust while running. The carb has some "repairs" done to it i noticed during the carb rebuild. Including some silicone holding where the choke diaghram is together. Is this 4180 a carb worth messing with or is there any suggestion for a good Realitivly cheap carb on the market. I'll be using this truck mostly for a daily driver / hunting rig and once in awhile pulling about 8 to 9 thousand pounds.
Thanks for the help

Its worth buying a rebuild kit for around $35, and giving it a shot. The silicone could be a quick patch job or maybe the screws are stripped. Those plugs shouldn't be that hard to remove, then just turn them all the way in and then back them out about 1 1/2 to 2 full turns as a starting point. If you never rebuilt one before its not really that difficult. Just make sure you get the correct rebuild kit, and follow the instructions. Be organized about it and clean everything with carb cleaner and blow out all the little passages with compressed air or with the carb cleaner straw. Also, if you have the egr spacer plate under the carb, remove that aswell and replace that gasket. Buy 2 of them gaskets and sandwich some sealant between them, or make one out of heavy gasket material.

Figured out the problem. Wasnt the Carbs fault at all. It was that EGR valve on the end of that EGR plate. Seems to be sticking open allowing air to keep cycling back into the carb uncontrolled. was super heating my air at the carb, and out my exhaust. The other morning while it was warming up my Exhaust pipe was cherry red all the way back past the doors. Nothing like walking out the front door and seeing a red glow under your truck to get you excited.
Since we dont Check emissions here in North Dakota i plugged the hole where it comes up into that egr plate Truck is back to its old self now. this is just a temp fix, to make sure thats what it was of course they always start out as temp fixes until next time.
Ill be tearing off all the Emissions stuff here before to long. Ive seen a couple good threads here on the Forums. Thanks for the help.
