New Here, EZGO w/75lbs Compression
 

Im new t this forum and have been reading a lot of posts on here,
this site contains a huge deal of information on it! with out going through
all the posts, i have a 1984 EZ-GO gas cart. enigine tag says c25-2pg 244 84-0948

i had this cart given to me and i had some questions.

when i compression checked it, it had around 35 lbs, then i took the air filter
assebly out and it kicked it around 65 lbs...so i unbolted the exhaust and that gave me 75lbs...

i puleed the engine out and cleaned it up this morning and took the top part off to see if it had a busted ring and it didnt, the rings are pretty thin in spots but not broken, is that enough to loss that much compression? or should i be looking else where for a problem?

also i can feel a lot of air around the shaft side of the cam that goes to the pulley, looks like that seal might be broken, would that casue loss of compression?

It sounds like a crank seal is bad.I am not an expert but I believe you have to pull the engine to replace the crank seals. I would also replace the bearing at the same time.

Hello ChubbB,
The worn seal on the crankshaft will not cause low compression but it will eventually stop the engine from running. As you probably know a 2 cycle engine needs a sealed crankcase to generate the pressure to run the fuel pump and transfer fuel from the carburetor to the crankcase and then to the cylinder.
The low compression is almost certainly caused by worn piston rings and so my diagnosis is that you simply have a tired old 2PG engine. The good news is that all the parts are available and for ~ $200 you could have a handy little cart with an engine that flies. You don't need to be an engineer to do this but you should know your way around a wrench. You will have to buy a cheap two arm steering wheel puller and buy (or make) a tool to pull the clutch off. You should also be aware that as the engine is Japanese all the fittings are metric.
