Vibrating and strange pressure stuff

T1011 GENERAL PUMP,T SERIES 47, 4.0 GPM @ 2000 PSI @ 1450 RPM.

This is the rating on that specific pump that is listed on ETS website. I don't know if they did independent testing of it. The general pump spec sheet on that unit rates it at 4.5 / 5.5 depending on pump RPM speed

Is it a flow unloader (K7 or similar) or is it a pressure unloader? On a flow unloader a certain amount of water must pass through the unloader even when under pressure - I think it is 5-7 percent, but I never measured volume for sure.

It may be a bad unloader; I had a similar problem with a Kohler / gear box / 2021 a while back

NOTE Mr. Admin GUY:

.........whole thing shakes quite a bit and bogs down some.

..........shakes and bogs.

...........shakes like crazy and bogs down A LOT.

....hard to start even though I put it back the way it was.

Nah nah nah nah naaaaaaah nah......That's all stuff about the motor Mr Admin guy!!!! :nanner::idea::bow-down:

Neophyte. I have seen all those things with a bad pump or unloader. I am still trying to figure out how the burner blowing black smoke is linked to the motor. Actually, there is a way. I would be looking for a new ignitor to have on hand, if I was you.

It's a pressure unloader and the unloader is brand new. It's a belt drive. I've taken the bypass line out and observed it and the unloader appears to be doing it's job right. I also have zero pressure with no tip according to the gauge

Generator turning too slow because of the bogging down......When I turn the unloader all the way down to where there's little pressure at the gun the motor will run at speed, the water will heat and the smoke disappears.

From what you've seen so far Russ, could replacing those bent and broken parts fix the problem, or is that going to just be patchwork for it to do it again soon? What causes something like this?
 
Ding, low voltage, whether 12 or 120 will cause an ignitor or transformer to delay ignition. Sometimes, especially with a generator, if the engine is not turning or operating at full capacity, you will not have the generator operating at full charging capacity.
A bent pushrod and valve not opening would tend to cause the engine to operate at less than full capacity.
You can also burn out a transformer or ignitor in a low voltage situation. Thus, I would have one on hand.
 
Tony, I believe he just called you a ding...:D

The ignition transformer would be affected by the low voltage, but 120 volt transformers are pretty forgiving. The output voltage would be exponentially reduced by the input volts, so instead of 10,000 he may have 7,000, which will still jump a 1/4" gap nicely.

The motor speed is what is causing the smoke. The fuel pump moves 3 gph at 3,450 rpms. What doesn't go through the nozzle is bypassed to the tank. Unless you are using all 3, there's plenty of fuel being pumped, even at a reduced rpm. The problem comes in with air flow. The fan, spinning slower, reduces the air flow to the combustion mix, making the dirty burn.

In 12 volt burners, the ignitor gets a double whammy. Not only does the low voltage cause the ignitor to heat up, the reduced air flow across the heat sink can't cool it properly.
