What engin oil is reccomended for the 1850 sport

goto COLEMAN POWERMATE 1850 SPEC/eHOW.COM

check to see if the cord is knoted up in the pulley. if not you either have a seized up engine or armature.

Check for low oil level. If level is OK, check low oil level sensor. Disconnect the wire to test.

30wt for warm temperatures.

The lack of DC output COULD possibly prevent the stopping. There are likely fuse(s) between the low voltage winding and a rectifier to generate the DC. SOMETIMES these are even inside the generator cover.

Here is the secret.... Remove the end cap of the armature and the long bolt securing armature assy to the engine shaft.

Tip the generator vertical so that the bolt hole is UP.

Put several rags on the back of the engine that is facing up. (Important)

Find or purchase a bolt of exact size at least 3 inches long that will screw into the hole that is facing up.

(With bolt in hand)

Fill the hole all the way to the top with any OIL.

Thread the bolt into the hole and turn with a wrench.

When the aramture separates it most often will make a BANG and scare anyone nearby!

Lift armature away from the engine.

Use rags on the back of the engine to clean up oil mess.

That is it in a nutshell.

is there an oilprotection on the gen. disconnect the cable and try again

3000 miles on any car is reccomended, even synthetic only oil i woould only go 4000 becasue the oil picks up dirt and then clogs the oil filter

Regular unleaded gas. 10W40 or mfg. suggested oil is fine.

Whose engine do you have? Briggs and Honda have websites where you can down load their manuals and replace the rear seal.
