Use TWO STROKE ENGINE OIL in the pump. If not using an automatic oil pump, then mix the gas and oil 32 to 1. That equals 4 ounces of TWO STROKE ENGINE OIL to one gallon of gas. NEVER use motor oil in the gas. Only two stroke engine oil. There may be an oil build up in the crankcase. Do a 64 to one gas/oil mix for awhile. Watch closely. when the smoke reaches proper levels go back to the 32/1 mix.

Hi Pamela:
Smoke from the muffler will be from unburned fuel (blackish) or from oil (blue).
A compressor is a stationary engine so would typically be a 4 cycle engine. It would have an oil dipstick and burn straight gas.
I'd be checking the fuel.
- If it is using oil then that would be where the smoke is coming from. If you check the spark plug it will probably be black and fouled with the oil residue.
That would indicate that the unit has seen a lot of use and needs overhaul or replacement. Some of the contractors in this area plan on replacing their gas engine compressors every 2 years. They tend to run long hours, and get tired.
Sort of like me.
All for now.

check your oil level maybe it is more than full if it is good, check your muffler if there is white smoke coming out. if there white smoke coming from your muffler you have a problem in your piston rings, need to be change. thanks...
Depending on if you laid the engine over on its' side, there could have been oil in the muffler. It may take some time to "burn" this off. It will also come from the muffler. Given enough time the oil will get hot and smoke off of the muffler. Then it will no longer smoke.
I hope this answers your question.
White smoke (steam) indicates antifreeze burning in the cylinder, or trying to, check again to see if it's blue tinted smoke,(almost looks white, but has a tint of blue, and it lingers in the air a lot longer) check the radiator level, and a compression check will determine the condition of each cylinder, evaluate the spark plugs, (there are charts on line) (this determines if the air fuel mixture it correct) let me know what the out come is.
It sounds like a lot of "blow-by" which means the rings or piston is leaking compression in high amounts carrying oil and water vapor to collect onto the vent where it drips.
Check the dip stick to see if you over filled it.. You shouldn't have oil above the top line... If you did over fill it remove the dip stick and tilt the mower to the exhaust side to drain on the excess oil out of the dip stick tube...
If it's not over filled with oil the engine more then likely shot and it's time for a new mower..
