YM2210 injectors, fuel pump, problem??

[Fire260]

Hey Guys, I have a YM2210 I got about a month are so ago and I'm trying to fix it up, it has had a starting problem and doing some troubleshooting, I pulled the injectors #2 had a lot of carbon buildup on it #1 was not bad, cleaned that off and hooked them up upside down to see how they spray, seems like it is not right, not atomized right, what do you think, the cardboard is 12in away, Plus i was thinking my injection pump was not putting out the psi it should,I will get a video of it shortly.
Thanks for your time and help.

It is evident your injection pump is putting up enough pressure to pop the injectors, however, I don't believe your injectors are atomizing like they should, especially the one on the left. Take this as an opinion, not a fact. They are suppose to pop at 2275psi with minimum 1707psi.

Yeah, I would say u should go after the injectors also.. the spray pattern is off..

Would you guys say get new ones or clean them?
Thanks for your help.

I would order new ones & clean the old ones while I wait for the new ones to arrive.

OK i will get new ones, One thing is when i did this test the throttle was in the off position, should it have fuel in the off position?
Thanks for your time and help.

No, should have been full throttle. You shouldn't have got anything unless maybe your tractor has a kill cable and not shut down with the throttle.

I will need to recheck when i get home, It only has throttle, I did so much different stuff last night i cant remember on the position of my throttle now. :confused2:
Thanks for your time and help.

I bought injectors for the YM240, $100 each at the local diesel shop after they told me no one rebuilds injectors. Then on here people posted of course injectors are cleaned and put back in service. I suggest check around.

If i was smart thats what i should have done but......... so i did order new ones, i did need some other stuff so i just ordered it ,got them from Aaron, I did take my old ones apart and cleaned them and they look good now,did the 60-deg test with the nozzle to make sure it moves freely, I did find some replacement nozzles that BOSCH has, would have been allot cheaper if thats all i needed.
