JLG Manlift 40H Problem Solving

LTC1967 ยท 2015-03-18 23:12

Hello all, I have a JLG 40H the engine is LRG-425I-6005-A with Gas/LPG fuel and I'm having to a crank for a extreme extended time, then back firing when it starts, but runs fine after starting. Hope someone has some ideas on what could be happening.

    my 40ha is the same way, gas has been disconnected but LPG is active and after it first starts it's fine

    I'm suspecting oil pressure switch may be causing ignition current delay, trying to figure out if they can be by passed or if there is a way to check them for issues.
