Coleman Powermate Generator

I have a Coleman Powermate generator  model PM0401852.  The vented gas cap is pushing fuel out after running about 5 minutes.  Evidently this is a common problem with this generator.  I am trying to find a replacement cap, or can I just use an unvented cap.  I only use this generator a couple times a year when the power goes out.  Thanks

This is due to heat. Don't fill the tank to the top, leave some air space. The cap has to vent or the engine will starve for fuel and quit.

Thanks.  I will try that.  Our power went out for about 3 or 4 hours last night and I was afraid to use it.

Another dumb question.  I have never changed the oil on this generator.  I bought it used from a co-worker.  I had it serviced where I bought my mower when the pull start broke the last time I used it.  I want to change the oil but I do not have the engine manual.  There appear to be two filler tubes.  What is the reason for that?  Also , what is a good oil to use?

Prefectly normal for a Briggs to have two fill locations as these engines are use version machines sometimes one location is not accessible bit the other is.
 
Owners Manual
PM0401850-52
 
The engine has a separate owners manual but the oil should SAE30ND.

Thanks very much, your advice worked.  I took some gas out and it was fine.
