Re: Oil Scare - Universal M25

What were the pressure readings last season? Did you use the same oil? What kind of filter did you use before? Possible situations:

1. Electric gauge sender going bad or poor connections? A mechanical gauge might be an option?

2. A filter that is plugged and the by-pass valve is not operating? As you changed filters and pressure stayed at 25 lbs the old filter may have been faulty?

Not reving over 2,600 RPM is likely another issue. Clean prop? Nothing caught underneath?
Plugged tank vent? Pickup tube screen partially plugged? Proper fuel filters? Fuel lines kinked or de-laminating inside?, on & on & on. Doubt that it is oil related but if so, likely something serious inside. Let us know how it comes out.
