It was 8 degrees F below zero this morning and has been below zero for 3 days so I decided to see how my L70 Yanmar would start. It has not been started in 4 weeks.
After it started I manually controlled the throttle preventing full speed so oil pressure could build up. Oil psi was initially 50psi but slowly increased to 100 psi as it warmed up.
I connected generator to my inverter and turned off the utility power and ran it for 30 minutes powering entire house.
It started better than I expected, very pleased. You couldn稚 expect any engine to start any better.
It is a military spec engine with a 3 quart oil sump and bypass oil filter allowing 500 hour service intervals. It also has 2 intake grid heaters that preheat intake air and works quite well.
I bought this engine new because it had the features noted above allowing very long service and intake grid heaters for extreme cold weather operation.
