CF686F1292 Posted June 29, 2007 Share Posted June 29, 2007 I co-own a 47 model 19 fire engine with a 707 thermodyne gas motor. Recently when you get to operating temp. or near,she bogs down when you apply pressure to the accelarator,and trying any kind of hill is a definite no-no.if you let it cool down she'll restart. Has new gas filters,and fresh tank of gas....now I have hardly ever worked on gas engines,and she has a dual ignition set up(diesel man through and through). was wondering if it was from running years of unleaded fuel or maybe sludge built up over years? Trying to get it to run properly as we want to take it on a 45 mile round trip to an antique fire apparatus show,and would like to run the pump while there. Thanks for any,and all help.
