Cold weather generator running

Last week I had to run my 6250 coleman generator outside at about -35 C. In about an hour it started to blow oil from the generator end it appeared. Ia there a solution short of having to enclose and heat the area?

I don't believe you have a problem with running your unit out in cold weather, it just does't make any since. There have to be a problem with the engine. If your unit is new or has been used very little, it is not broke in and has a to much blow-by. If this is the case you will find oil in your air clean and/or muffler. To fix it problem you need to change your oil and replace it with a organic oil which means not synthetic. Run your unit under 1/4 load for 15 minutes in your case about 15 amp at 120vac. This step it up to 30 amps at 120vac of 15 minutes then 45 amps for 15 min. Then about 60 amps for a good hour. After that step the unit back down to 45,30,and 15amps to allow the engine to cool-down properly. If you load your unit with 240vac instead of 120vac just divide the amps by two giving you 7.5, 15, 22.5, and 30amps. This should break your engine in. If you are still leaking/pushing out oil you more than likely have a bad seal, gasket, or something broken in you engine internally.

Make sure the sparkplug is clean and gapped. Unloosen the float bowl slightly and drain about a half cup of gas out of the bowl. It is possible a little condensation got in to the fuel. Tighten the bowl nut slightly and try to start the generator.

How often should I change oil in my model 6250 powermate. Thanks


For some reason people think that the oil goes bad in 2 weeks because it is a small engine, but if you compare 3,000 miles on your car to hours, you would never change the oil in the generator. I don't think I have changed my lawn tractor oil in 15 years, and it is still clear, never broke down, because in 15 years, I've probably run it, 150 hours? It's about due. I hope this helps.

Do check the oil after it has tried to start. Low oil cutoff would certainly cause the problem. Look for the "lost" fuel shutoff valve... there usually is one.

the usual reason is a stuck float in your carburator , can be caused by dirt/rust etc , remove carb bowl and clean , there is also a very small needle valve which is attached to this float ( metering needle ) these can leak.
if all else fails always turn off the fuel supply to the generator whilst not in use

Coleman Powermate 6250 only runs with choke closed/air restricted


A call to Elliott Small Engine solved my problem - Oil Guard. I had checked the oil and it was just a little low but seemed well within the normal range. I was told to add more, bringing it just over the Full mark. It seems that the low oil protection system is very sensitive and shuts down the engine even when the oil is withing 1/8" of the mark. I added about 2-3 oz of oil and no more problems
