SOURCE: what kind of oil do I use in my 675 series engine
4 stroke synthetic is most likely what you'd want to run if it's a new unit to yourself. Otherwise any 4 stroke motor oil is fine, you can find it at any retailer that sells small engine machinery.

If your carburetor has sat for a few months with fuel in it, the fuel may have gone bad. Fuel turns to turpentine after a while and leaves light yellow deposits behind. These deposits will keep your carb. from working properly.You need to dip the carb. in carburetor dip for a few hours to get rid of the deposits. You can also take the carb. to your local parts store where they may do it for free.
You may also have to replace the gasket and needle valve too if it has been sitting. So basically, you need to do a carburetor rebuild. If the float sounds like it has liquid in it, you will need to replace it too.
Good Luck!

Item 8 on the die of the engine is porting oil to your carb. Most of the time the reason for this is that someone seriously over-filled the engine with oil so as a crankcase breather it is shoving the excess oil out of the crankcase and into the carb throat. Hence your seeing massive smoke and the engine eventually dies out.
Re-check the engine oil level. There are 2 lines on the dip stick. The oil should NOT be above the upper line.
If the oil level is fine then remove the crancase breather from the side of the engine and submerse it a cleaning solvent. (I can not tell you to use gas but I do) Let it soak for quite a while (8 hours) And then clean it off with carb cleaner and re-install it.
I honestly think you have a simple case of too much oil in the engine. Adjust the oil level to the proper levels and try again. It will smoke for a couple of minutes while the residual oil id expelled but it should snap out of the current symptoms shortly there after.
If none of the above correct the problem just respond here and I will help you.
