Hi all, I'm new to this forum and hoping to find out some information about my D6 9U27151 I recently bought and am putting it back into service. It has a rear cable control unit for the blade. I removed an add on hydraulic system from it that needed more money thrown at it than I thought was necessary to use the blade tilt cylinder. I would like to remove the cylinder and replace it with the manual adjuster like the opposite side has if I can find one. I have used it some but the pony is not starting reliably enough for me to consider it ready to go. It obviously had a carb kit put in it recently before I bought it but the rust from the tank got to it in a hurry. Thank you for any information!

My Bible shows your D6 to be a 1957 year model
The class of 57 had its dreams.
Make lots of tracks with it

Remove pony tank, clean and line with RedKote or similar compound. Then if it still won’t run without choke, drill out soft plug that lines up with the passage from below main jet to the hex plug holding in high speed metering well next to the cast iron carburetor Venturi. Caution is advised tightening the two bolts that hold carb bowl onto Venturi section. Also make sure the gasket between has the center bulls eye ring still intact before reassembly. Also best to remove the idle screw and long brass tube that goes all the way through from right side of carb to stick into the bowl through that center ring on the gasket. Put it back like it was but about 1 turn out from snug tight is a good starting point. That one is adjusting AIR, so backing it out leans the idle mixture. The main jet screw is vertical sticking out the top of the bowl and it is normal, out to richen, in to lean the high speed/load mixture.
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time:D

Thanks ccjersey, I have the carb off and hope to have my kit soon so I can get it all cleaned up. I definitely think I need to drill out the soft plug
