I had the fuel injectors for my Bobcat checked this morning and the only problem is that they all are 500 pound low. How much does that impact the performance of the Bobcat. It does not have the power it used to but I do not know if it is worth the money to have them fixed if it is not going to improve anything.
The fuel injector would cost approx. 70$ to get rebuild, but according to the manual I can add a washer to increase the pressure and that is a lot cheaper than rebuilding the injectors.
Any suggestion or advice is welcome.

I have no idea how much it will affect performance but if they are designed to pop at a certain pressure,then that is what they should be set at. There will be a range for the spec and I presume your test indicated 35 atmospheres or so below the minimum of the range. You do not generally need to rebuild an injector, just adjust the pressure with shims, washers or whatever they require to give the correct pop pressure. The injector experts may be able to tell you how much difference it might make and if this indicates any other woes with these particular injectors.

The manual says 1 washer adds 500 so I will try that but it did not say there are several thicknesses to choose from so I had them order the thinnest which is 1 mm.
