OK I will start. I have an SH .28 in my LST, I just traded for it a week or so ago. I will fire up as soon as I hit the starter and remain running until i take off the heater. As soon as I do that it dies instantly.
I have changed the glow plug 3 times, switched out carbs and adjusted high and low needles until my screwdriver wore out. Also switched tanks and fuel line. Nothing works, runs fine with heater take off heater DIES>

HELP!!!!!!!!!!!!!!!![&o]
