I'm having trouble starting my Generator it model is gp5500

Customer Question

I'm having trouble starting my Generator it model is gp5500
It only has 7 hrs on it it has started plenty of times since I bought it
It has gas with stabilizer in it
I tried using starter fluid last time and it took me 25 minutes and almost a full can of starter fluid, it back fired 2 but it started. I was gonna try the same thing today if needed, but do you think there is an easier fix. Spark plug if giving charge. I have not changed the oil in 3 years, but since it has not been used so much I thought it didn't need to.

Remove the spark plug and put a teaspoon of fuel direct into the spark plug hole, re-install the park pug and see if it will fire. If it does , the carburetor is not letting fuel in. Check fuel to carburetor them drain the fuel bowl to check for water.

Ok I will try

Ok it started right up then stopped
I'm assuming no gas through carb
How can I address that or do I need to replace it?
Expert:  Curtis B. replied 1 year ago.

Try draining the carburetor float bowl.It may have water in it, be sure you have fuel to the carb from the tank! Here is basic carburetor disassembly. Yours will be similar.

Customer: replied 1 year ago.
Ok carb was fine drained existing fuel and put fresh fuel
Still won't turn over 10-12 pulls
I removed carb and the part that it was attached to (don't know name) nothing looked odd
Expert:  Curtis B. replied 1 year ago.

Was carb bowl full of fuel?

When I removed all I looked inside with a flashlight and there was fuel in there. It didn't go any further. I'm not sure what parts and names are ***** ***** point me being a novice
Expert:  Curtis B. replied 1 year ago.

If fuel is getting to carb, and none to the cylinder, has to be blockage in the carburetor. We know engine runs if you put fuel into the cylinder. Main jet, which is the bowl bolt and the center stud , it screws into ,can be plugged with dirt or debris.???

Customer: replied 1 year ago.
That looked clear and clean
Expert:  Curtis B. replied 1 year ago.

If you hold hand over carburetor throat, do you get good suction? If not, mounting gasket could be leaking. Some reason fuel is not being sucked into the cylinder.

Customer: replied 1 year ago.
I have see if I can
Can that be done with tank off? I had to to get at carb
Expert:  Curtis B. replied 1 year ago.

Yes, you just want to know if it sucks, not trying to start it.

Customer: replied 1 year ago.
Ok. Will try.
Expert:  Curtis B. replied 1 year ago.

OK, if it sucks, it should pull fuel in.

Customer: replied 1 year ago.
Just to be clear
I remove the carb again
Then cover the opening and try to start?
Expert:  Curtis B. replied 1 year ago.

No, cover the carburetor opening, you want it in place,

Customer: replied 1 year ago.

Customer: replied 1 year ago.

Expert:  Curtis B. replied 1 year ago.

Customer: replied 1 year ago.

I can't get completely flat over the opening, but I feel air being pulled in
Customer: replied 1 year ago.

Customer: replied 1 year ago.

Suction
The opening had gas sitting in it after removing carb
I pulled the rope it opened and the fuel went inside engine
Expert:  Curtis B. replied 1 year ago.

Customer: replied 1 year ago.

Let me know.

Customer: replied 1 year ago.
It's backfiring but it won't turnover
almost does feels like it wants to
Customer: replied 1 year ago.
You still there??
Expert:  Curtis B. replied 1 year ago.

Sorry, I have a Kubota I was trying to get together, Backfiring? As through the carburetor? If it sounded alright when you did the gas in cylinder test, it should run. If it didn't, then I would think the valves could need to be checked, or it was out of time. But if it runs, that means it has to be fuel problem. You may have to get a new carb!
