With recording tape, it's called "stiction".    In an engine, I'd look for oil that turned to grease.  Odd, because once you got it moving, should be able to set an hour and still be free.  Can you feel any play in the connecting rod ( upper or lower ) ?

something in the piston area seems to be the only large enough surface contact to "stick". 

Maybe Felts on the bearings ?

With the injector off the engine, be very careful to not get high pressure spray from the injector, into your flesh.  Nothing bad happens for a couple hours, then your flesh starts to die from poisoning. Amputation is common.

The longer the period of time before treatment, the more risk you are taking on. At first, injections may feel like a bee sting or wire prick and the entry area may look like just a pin prick. Do not let this fool you. The size of the entry wound is a poor indicator of the seriousness of the injury. What looks like a simple puncture wound is in fact life threatening. The area around the injury typically turns red and swells within a couple of hours. Throbbing and numbness follow. If left untreated, the injury can lead to amputation and even death.

Lister Based Generators / Re: Gen head with inverter?
« on: July 21, 2021, 06:09:48 AM »
An Inverter Generator, is a merely a generator that powers a Inverter.   if the load on the the inverter is small, the engine runs slower.
 The "generator" part is usually 3 or 6 phase, gets rectified and then drives the inverter for your 120VAC

you can simply back the  nut at the injector off a turn or two and see if any fuel dribbles out as you crank (with no compression) .  No dribble = clog.   But that pipe is generally under very high pressure from the pump, and would push any clog through and maybe into the injector.
Does fuel gravity dribble out of the pump inlet if you loosen the inlet nut ?

Hi Gentles

As far as I know that power factor is relatively to the magnetic and heat losses. Wont you all agree?

Power Factor is related to the offset between the phase of the voltage and the phase of the amps of the load.
It is caused by Inductance and Capacitance in the loads.

https://en.wikipedia.org/wiki/Power_factor

 ( excerpt) Lagging and leading power factors
Power factor is described as leading if the current waveform is advanced in phase with respect to voltage, or lagging when the current waveform is behind the voltage waveform. A lagging power factor signifies that the load is inductive, as the load will “consume” reactive power. The reactive component Q {\displaystyle Q} Q is positive as reactive power travels through the circuit and is “consumed” by the inductive load. A leading power factor signifies that the load is capacitive, as the load “supplies” reactive power, and therefore the reactive component Q {\displaystyle Q} Q is negative as reactive power is being supplied to the circuit.

I would prefer not to use balancers, but to order some extra batteries with the initial order, and then sort/bin the batteries, so you build a bank with all matched batteries, and top or bottom balance the bank.   (and hold in reserve the low capacity & high capacity cells )
Then just rely on the BMS to monitor cells in case one fails.

Somewhere on the forums, I remember a post about using an aluminum can as shell material.  Of course now,
i can't find it.

Hi Gentles

This afternoon take a few minutes to exercise my arm, and stretch the con rods to the 12/2.

a vid is at FB, here: https://www.facebook.com/valdemar.pedrosa/videos/4126863360714080

Cheers

you could try sun baking the magneto, try to cook the water out of it at about 160F for a couple hours.  Not so hot as to damage parts, but warm enough to drive out moisture deep inside.    if it works, you know it's a moisture problem.
