adjusting one barrel carb

landacre · Jun 20, 2007

anybody have any tips on adjusting the carb on a 170? i'm used to four barrels, i can't seem to get this thing adjusted right.

Well since no one else answered...Knock it in the head ....KILL IT .... turn the one adjusting screw in all the way count the no. of complete turns ...turn out 1 and 3/4 complete turns ....make sure the choke is completely open ...then start it... remembering where you where orignally .Twist it back and fourth about a 1/2 turn both ways slowly ...When you get the highest idle that should be it....YOUR supposed to move twist it slowly ....Now you can take a can of either with a hose or nozzle on it or if your chicken "discramer" spray it around the base... throttle.. joints... gaskets ...If the idle raise you have a vacumn leak.. fix it and start over....you can also go down thru your intake ports for vacumn leak check ...

I agree a vaccum guage can help you if you have one. Adjust to the highest vaccum otherwise as stated adjust to the highest smooth idle.

And if that dosnt help open it and look at the jet. I had one on a mustang (6) that someone drilled out the jet it ran real rich good luck with your's.

And check your timing!!!!!

I used the vaccum gauge to fine tune both the timing and the idle mix.
Since then, I have had excelent results with idling, starts and fuel consumption. The gauge will also let you know if you have a leak. Try this link for some additional help http://pagead2.googlesyndication.co...360&u_his=1&u_java=true&u_nplug=13&u_nmime=42

hey guys, i adjusted the carb and set the timing and she purrs like a kitten now! i really appreciate ya'lls responses. now if i could only get that 6 banger to break 55 on the highway i would be in great shape. we all have dreams, right?

Take those low rider tires off it and put the 35's back on .......it'll run 55
You just have to figure out how to hang on!!!!
