How hard is it to clean fuel injectors in a Suzuki DF 140?

Question

02 Suzuki DF 140 with very little hrs. like new, sat for 2 years now it wont run. I have narrowed the problem down to 2 possibilities. Either a varnished fuel pump or varnished up injectors. Its simply not getting gas to the intake. Any suggestions???

Answer 1

check the fuel pressure via the shrader valve on the fuel system.  needs to be 36 minimum.  to clean the injectors, remove them and soak in mineral spirits for 30 minutes.  then tap the nozzle end gently on a saucer or such and rinse off.  you'll see plenty of carbon probably.
