Found a new door/window, so now I can start sorting out the other problems. Keep in mind I am NOT a mechanic nor could I even pass for one. I've only been doing most of my own work since 2011, and while I'm a pretty quick learner and usually successful when I set out to fix a mechanical problem, there is a LOT that I don't know. If I ever sound clueless, it's probably because I am.
My main problem with my little D-50 right now is the horrible fuel mileage. I'm not sure what these trucks usually pull, but I know it should be doing better than the 10-12 mpg that it's running right now. The first thing I'm gonna try of course is to replace the fuel filter, but what else could be causing that kind of mileage?
Again I'm not particularly an expert, but I'm kinda feeling like it's something with the carb, it was running rich as hell before (strong gas smell, flooding, etc) but I had a buddy fiddle with it and the gas smell and flooding are gone at least. The carb is new, but the last owner DID admit he didn't know what he was doing and it probably wasn't set up correctly. It's just got a Mikuni carb that I'm gonna replace eventually, but how would someone that only vaguely knows what he's doing tune it to a somewhat acceptable point as to eliminate that as an issue?
The other big issue I'm having that may or may not be related to the same issue that's killing the fuel mileage is a serious lack of power. Overall it's just sluggish as hell, and I've noticed one thing with it that has me somewhat concerned. Mine has the 3spd auto, and it's my understanding that when the pedal is pushed to the floor or near it that it downshifts to 2nd for hills or whatever. Most of the time this seems to be how it works, but it's not consistent at any speed or RPM. Good example is one specific hill that I hit daily, it just stays in 3rd the whole time and it's lost about 10mph by the time I get the top even with the pedal to the floor. Does this sound like an issue or is it normal or do I just have the whole system confused?
