If you want to stick your old feedback carb on it, it will work. I have been running mine for a year now with all the wires gone. It idles and starts extremely well, and runs out well also. Does 80 mph easy on the interstate with no hiccups at all.
I did notice I am getting what think is crummy fuel mileage. I checked it the other day, I am getting 16.5 mpg. My other little ranger with the 2.9 fuel injection would get 20 mpg on a summer day, less during the winter. Of course I can't leave well enough alone, like I said the feedback carb runs great. But I was thinking about experimenting with the feedback solenoid and see if I can get a little bit better mileage out of it.
I am figuring I can basically change the jet size by pulsing the solenoid more or less. Thinking about just getting a momentary switch to pulse it by hand as I drive down the road to see what happens. If it has a large affect, I might get a repeat timer that I can set to dial it in.
I'm afraid my feedback carb is too far gone.... LOL it has been robbed of a few parts to rebuild the one I have on it now. I mean it could be used, but I had a lot of trouble out of it.
This B2 seems to be running well. I am just curious if it running as well as it can be. I would say any carb issue is more about me learning on how to work on them vs them being really an issue.
The reason I am on jets now is just to confirm then. It can change from where you live and drive and all etc.
Also, I do have a slight shudder at 45 mph when I am pulling a hill or something. It could be something else, but the shudder goes away if I give the engine more throttle, so I don't believe it is transmission or road speed related. I think it is more engine related.
I don't expect this thing to be a speed demon, but I would think it could pull a hill in OD at 60 mph.... maybe I'm asking too much?
