[QUOTE="Thormx294, post: 108787, member: 18018"] I recently purchased a pair of 1998 and 2000 bobcat 873 in unknown condition. I got back items back to my shop and running, made repairs and both run and drive. Both units have issues with starting. One unit takes about 20-30 seconds of cranking to actually start then starts up and runs fine with no smoke. Sometimes this is so much cranking it requires a jump pack because I drain a 1000cca battery. I believe this is fuel related but am not sure. The other unit instantly try’s to fire off but won’t , it requires you to hold the key while motor is trying to run to keep the starter engaged forcing it to run basically. After doing this for 15-20 seconds it will poorly run on its own. With the idle set at high/wide open it barely runs but stays running then after 30 seconds it idles normally. For about 2-3 minutes it huffs a whitish blueish smoke and then clears up. When I got the machine it had a bad mechanical pump feeding the injection pump(the unit ran while squeezing the primer bulb to push fuel so I replaced the pump and that solved that issue). The unit has a new fuel filter, mechanical pump, primer ball, clear line between the primer and the pump. I believe it is still a fuel issue causing this problem. Any ideas would be helpful or things to check / replace Thanks [/QUOTE]
