Questions for early 80's EZGO Gas owners/knowlegeable personell.

Ive been searching for parts for what i assume to be a 1980 marathon? Serial is 80J27-212739.... When i find parts that include 1980 in the description, take the driver side rear axle, they are incorrect. The one that appears to be correct is for 1983+ ... also, I cannot find a fuel pump listed that covers 1980, but the one for 1983+ also appears to be the same... WHAT AM I MISSING HERE?!?!? haha... Any info is appreciated, if i could post links yet i would put a picture of the cart up but im too new. There's another post titled "New Guy's Cart Build" that StoveBolt posted pictures of it for me in. Any info would be great!

Welcome to BGW 80 would be correct by the numbers. The topic of 80 parts has come up before and as for as I know the 83 parts as for as the engine will work. I've seen different steering on some but also don't see why they wouldn't change over.

Pete, a short history of the PG engine, enjoy.

-In 1976 the so-called '2pg'--a 244cc, Fuji Heavy Industries/Robin Engine--with an internal starter generator (st/gen), became standard. Repair parts are still available except for the crankshaft assembly, the voltage regulator/starter relay and the internal st/gen stator & field.

-In 1980, an external, Hitachi brand starter generator was introduced and the engine was modified. The crank bearings, drive clutch, point set & condenser, voltage regulator and the engine frame all changed.

-1981 ushered in an electronic ignition system, which did away with the golf carts point set & condenser altogether, and the point activator lobe on the crankshaft soon went away too. Except for the addition of an oil injection system, this engine went virtually unchanged until 1989 when the 3pg golf cart engine replaced it. Although the two engines are similar, many parts are very different.

-1983 was the oddball year for the 2pg engine. The muffler was placed behind the engine and it laid down instead of standing up. The '83 golf cart had a different engine frame, muffler & exhaust stack. It only lasted one year though...lots of problems.

In '84 the E-Z-GO golf cart went back to the old exhaust system & stand-up muffler on the driver side of the car.

1988 was the last full year of the 2pg engine. A larger golf cart carburetor and another change to the muffler & exhaust system were implemented trying to get more power for the car. The st/gen bracket also went through several changes as the increased power caused the original bracket to break apart.

In mid-year 1989, (early '89 models had the 2pg engine) E-Z-GO changed to the '3pg' engine, leaving the old 2pg to history. The '3pg' engine has the spark plug turned upward, and the whole engine is rotated such that both clutches face the driver side of the golf cart. This rotation allowed for the differential to be changed from a hypoid gearing to a more efficient helical gear design, a change that persists to this day. The lay-down style golf cart muffler for the '3pg' engine is in front of, and slightly above the engine. The piston is about the only part that works in either engine. The crankshaft & clutches, the exhaust system, the carburetor, air intake & control cables all changed.

1992 is the generally accepted date that the twin-cylinder 4-cycle engine became the standard power plant but in fact the 3pg engine can be found in golf carts as late as 1994.

Thanks guys, by the engine as well, it's an 80 according to Dave's history post. Weird, guess I need to pay close attention when ordering parts. Got the drivers axle, new ball joints all around, and fuel pump on the way =)
