If the Impco or Maxitrol demand regulator is faulty it will be too rich on start up and if fact sometimes will not start at all. We do not work on small sets much. But the IMP52 matches to the Impco55 mixer, I am not sure of the Maxitrol
that might be equivalent but the Maxitrol ES402 (EV now I think) matches the Imp53. Both of which are prob to large for the small set. And remember the demand regulator has to be upside down with the spring removed with negative pressure at the mixer.
If it has excessive fuel all the time then I would lower the pressure down as 11"WC would be the max that we see.
We work on some 400kw natural gas black start gen sets which are in a facility with some NG 300 rpm engines that have the turbo chargers outside of the building and the turbos are about 8-10ft in diameter. | |
