ok here is my prob i keep burning out glow plugs the car runs at 210-220 deg and runs great but when i shut it off and then go back to start it the glow plug is blown besides the high end needle could it be that the low end needle is too lean? or the other needle by the pull slide on the carb ? its driving me crazy and at 10.00 per plug its getting exp if you guys have any idea's please let me know
