I am wokring on a MSU 500 that ran out of fuel and now , will not start. Pump runs and the injector shoots out a good pressure. There is good spark. Valve clearance is correct.How much pressure does the pressure release system release ? I am showing only 8 to 10 lbs ( unless my guage is bad). The unit was possibly submerged ; lots of mud on everything. Any suggestions ???
