My 8kgenerac natural gas gen runs great solenoid checked out good also regulator is good sometimes it will start on auto but most of the time I have to put hand over air cleaner and it starts right up is this a faulty choke

Is this a natural gas fueled generator? Sounds like a fuel problem, i would go through the fuel system and find out whats wrong. If its a natural gas/propane unit its most likely a bad regulator or low pressure.

plz check auto chok ....... but main cause may be in gas kit

Check the comprssion, if you are sure you have a spark and gas. Is the fuel been delivered to the cylinders? Check the fuel solenoid for power, if power is present the demand gas regulator maybe gummed up. LP companies put a waxy lubricant in the gas and over time this can build up and harden in regulators. Also during crank observe the throttle is it going open as it should? if not suspect a control issue

The fuel is controlled by the gas valve, the amount of gas is controlled by the regulator, I would verify that the inlet gas pressure is within the limits of the gas valve/regulator. The surging is likely the fault of the regulator and could be as simple as a spec of something in the orifice that allows gas pressure on the top of the gas regulator diaphragm. With the surge there must be an accompanied change in gas pressure at the gas valve outlet to the burners, use a "U" bend manometer to verify as they are the most simple and accurate and react instantly with no "averaging" software to wonder about.

running out of time and too rich
suggest that you call in an auto gas technician to check and adjust the regulator /converter for the gas to get it running right

Hi men2cu...
Try this method, being you have spark and gas getting to the carburetor...

Get a can of starting fluid, and spray a small amount of it into the carburetor and then try to crank it again...if it cranks and runs then problem fixed...if it cranks and shuts off right away, then you have some trash in your inlet valve in your carburetor.
You can try tapping the carburetor lightly with a hammer and sometimes that will dislodge the float needle if it doesn't dislodge the needle valve then the carburetor will have to be disassemble and cleaned.
Once this is complete your generator should run fine.
Please take time to rate me

check pressure of the fuel line running in to the regulator it sounds like you have not enough gas coming in and the if it is good was the screw reset after the bellows was replaced?.
ether way it sounds like it is starving for fuel. hope this helps

Hi,
No.. the gas pressure that is run out to the grill should be low pressure allready...just hook it in leak test it and you are good to go....
My grill sits right by my meter about six feet away... I tee'd off at the meter installed a valve and then run right into the grill....works great!!

According to the Comfort Glow Website, this is a Natural Gas unit. If you use propane you will need
a minumum 100# LP Cylinder and a pressure regulator. I have a Comfort Glow unit and went through the same process.

If you have it hooked up to a 30lb cylinder without a regulator I would think that if you purged the gas line
of air you should be able to light the pilot.

On a new unit you can expect to push the spark ignitor button at least a dozen times while holding
down the gas valve button.

Good Luck

Fix another regulator before gen set gas supply
