Hello everyone I just bought my first stand up an 89 js550, I redid everything paint, gaskets, hoses, ebox, throttle cable, turf, etc. I bought an sbn44 and changed the low jet to a 110, the high to a 125 and the pop off to the black 80 gram spring. On a stand it’ll start up well, in the water it starts for 1 second and then dies. I’m not sure what the problem is. Any help is appreciated.
