D-19 carb/Fuel useage?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I replaced a blown deisel engine with a 6B230 in this with combine carb/tractor gov. I have rebuilt carb/new float/air filter. Now the rest of the story,I understand a stock D-19 is fairly hard on gas, but this past spring pulling a 214 disk we could put close to 100 gal. per day through it. Even planting with a 4 row planter still uses alot. The engine never runs clean. Also I tried a smaller main jet, and the load screw makes no difference in the way it runs. Could it be getting fuel from another source? I wonder is carb junk?  May need different carb if so which one? Thanks Bill

	A D19 (6B-262) at Nebraska Test used 6.23 GPH at 2000 rpm full load making 71.54 hp at the pto, so in 10 consecutive hours of 100% load (which would be hard to do) that would only be 62 gallons of fuel. I'd expect a well tuned 6B-230 to use less than that and be around 5.0 to 5.4 GPH (a D17 is at 4.0 GPH). When you've been in the field working it for a couple hrs at full throttle, the inside of the exhaust pipe should be clean (depends on the brand of gas you use) ...I've seen a light yellow color, snow white, gray, and light green, but it sure shouldn't be black or charcoal in color. I'd say you got troubles.

	If the carb for a 230 is like the on for the 262, it is possible to install the load screw and not have the needle in the jet. The screw is long enough and will flex enough to thread in without cross threading. Also if the screw was in the carb top when assembled to the bowl the screw could easily be out of the jet. Seen it happen more than once and will burn all the gas that will go thru the jet, but not clean.

	I think Eric is on to it there...I know when I took my carb for my D19 apart without removing the power needle adjustment screw I bent the heck out of it and it took me a long time to get it back in tune to even idle correctly.

	First of all, when your swapping load screws, jets, etc from carb to carb, you have to make sure the carb your swapping parts with are both in the same family of carburetors. To me, that sounds like an awful lot of fuel being consumed. I'm wit' the Doc there. You could have a carburetor issue or an induction issue..... Steve@B&B
