I've got a '01 4300 (w/ 430 loader) that, more often than not, starts first time I bump it. The problem w/ it is that after running it, I can shut down & NOT get it to start again, even though seems to be getting fuel & has plenty of battery. I've changed the fuel filter and resorted to removing the right side cover & using the manual pump to be sure it's not starved for fuel. I've also had it start up for me after exhibiting this problem, so I guess you'd say it's intermittent...
