There is a three-part system to making any golf cart run. You need fuel that gets supplied by the pump and carburetor. Compression, which is a combination of the intake and piston assembly doing their things. Finally, you have the fire. Which is produced by the coil and the EZGO Ignitor for Gas powered 1981-90 models. The coil generates the high-level voltage needed to get a good hot spark. The ignitor is the unit that times it. This means that at just the right time, the ignitor sends a signal to collapse the spark to be regenerated. All of this happens hundreds of times per minute, and it has to occur at precisely the proper time, or the engine cannot run.The golf cart ignitor is usually a tiny, square unit with one to two wings for mounting. All you will need is a screwdriver and maybe a pair of needle nose plyers to unplug stuck wires. Call Buggies Unlimited and get your EZGO ignitor coming today.
