Okay, I removed the fuel bowl, drained out all of the bad diesel, and bleed the line as suggested. Anyway, when I tried to start the engine, it cranked and seemed like it wanted to start . . . close but no cigar. I've decided to go ahead and take it to the dealer. Although it was recently fully serviced (according to the seller) I'd feel more comfortable if my local Kubota dealer (in Andalusia, Alabama) gave it a thorough check to make sure all maintenance is up-to-date and everything is "field ready." I still suspect that the starting problem is bad fuel, but don't feel I'm at the point where I can confidently take care of the problem myself -- I wasn't kidding when I said I was a newbie when it comes to tractor maintenance! Spent too much of my career working behind a desk (U.S. Army Corps of Engineers) . . . didn't get much wrench time. But, I'm placing an order for the workshop manual so that I can begin learning how to maintain everything myself (I retired recently and now have the time). Thanks, everyone, who offered advice. I'm sure I will be back with more questions in the future. I'll post a few photos when I have my B7300 up and running -- and I will confirm that the problem was bad fuel (however, the service manager I spoke to this morning said he wouldn't rule out bad glow plugs). I'm sooooo anxious to get behind the wheel and see what 16 horsepower will do! Mama's vegetable garden needs lots of TLC and this little Kabota should make life a lot easier! Also, special thanks to the OTT member who sent me a copy of the operator's manual for the B7300 -- it is going to be a BIG help -- now I can identify what those extra knobs and levers are suppose to do! Again, thanks to all -- I'm very grateful for the Orange Talks forum -- it is a tremendous resource, especially for folks like myself who are just starting out.
