Ezgo 4 stroke smoking ?

[Seabb18]

I have the 295cc robins block when I bought it it smelt a little bad but didn't some to much . Now it smokes at idle constantly out of the exhaust and when I took it to the road I notice when I would hold the gas down it would excelerate fine but it looked like a 2 stroke cloud behind me . What's more common the valves or rings and piston ? Also what's the proper compression on this block ?

If it's smoking that bad it probably needs rebuilding (rings,seals etc...) ideal compression is 150-165 #'s and the lowest to get by with is around 125 #'s.I had an Ezgo (295 Robbins) awhile back that would only "show" smoke if you idled along @ a slow speed for awhile then opened it up so I replaced the intake valve seals and it stopped the smoking .

Also is it over head valve it seems to make a lot of noise from the oil cover area

Yes they are over head cam engines.

The color of the smoke will tell you the problem. You get blue smoke if it's oil. Brown or black is too much fuel. White will indicate steam ... I think you're air cooled so that's not a possibility.

Thanks for all the input and info it's burning blue so I am burning oil from somewhere I found a complete rebuild kit with new valves pistons rods bearing gaskets seals basically every thing I will need $300. Should I go that route or just fix what needs to be fixed ?
