AS SIMPLE AS THE DIAGRAM IS, IT MAY LOOK IMPOSSIBLE TO JUMP GLOW PLUGS. HERE IS AN IDEA TO SIMPLIFY IN THE BRAIN...

JUST JUMP THE NEGATIVE WIRE FROM ONE SIDE OF GLOW HEAT CLIP #1 TO THE POSITIVE WIRE ON GLOW HEAT CLIP #2. HOOK THE TWO REMAINING WIRES UP TO THE 2.4 VOLT SOURCE.
ATTACH BOTH GLOW HEAT CLIPS TO THE GLOW PLUGS AND FIRE UP THE ENGINE.

BACK TO MY ORIGINAL POSTING...IF YOU LIGHT UP ONE SIDE ONLY AT FIRST THERE IS LESS KICK BACK, IT WILL RUN FINE ON ONE CYLINDER, THEN SIMPLY (WHILE IT IS RUNNING ON ONE CYLINDER) APPLY HEAT TO OTHER SIDE. i THINK THIS WORKS VERY SLICK!
