Re: DT 175 Float Adjustment??
Actually, I believe they should be adjusted sitting under their own weight not with you pushing down on them. These are new float valves, right? If not go get a rebuild kit and install new ones before you do anything else. Also, since you have the carbs off I am assuming that you have cleaned them thoroughly with carb solvent and compressed air, if not do so.<br /><br />How come you disabled the oil injection system? What was wrong with it? Suzuki oil injection is pretty reliable if kept maintained (clean oil tank, clean oil screens, replace tubing if old and cracked). In addition to the obvious convenience, you use less oil, and since the oil is injected into the reed plate not the fuel, a gummed up carb (which you appear to be suffering from) will be less likely to cause a lack of lubrication and engine failure than if you use premix. You may want to reconsider this.<br /><br />While not impossible, it is unlikely that there are problems with the reeds. While you have the carbs off, look into the intake and check that they are all there, not broken, and all are laying flat on their plates. They would be way down on the list of probable cause of your problem. Focus on a THOROUGH carb rebuild. Mikuni carbs on Suzukis want surgically clean orifices.
