cHAMPION GENNY mod 75537i UPDATE PG 2

Have a 3100 watt champion genny inverter about 4 years old. had it in storage for a few months with STABLE in about 1/4 gallon of gas. drained all the gas from tank and carb and added fresh. took plug out and cleaned it up and reset gap. (plug only had about 15 hrs on it)
tried to pull start and nothing..... no sputter or even a attempt to start..... Anything else I can check or do to get it started before having to take it to a repair shop?

Thanks for any suggestions and help.
  • Yes, it's getting spark.

    It sounds like it's not getting consistent fuel. I would start by checking for obstructions in the fuel line and where it attaches to the tank, and in the venting of the tank. If those looked OK, I'd tend to suspect the float assembly and associated valve in the carburetor (assuming it has one). If there's a fuel pump of some sort, check that as well. If it runs properly with the fuel cap loose but not when it's properly tightened, it's a pretty sure bet that it's the tank vent that's plugged, and that is a very easy check to make.

    Are all of the hoses in good shape and not dry rotted or cracked in anyway.


    Yes they all look good and flexible, gas lines, air filter whatever i could see looked good

    OK will check the vents, I checked about the cost of a carb and it runs 39.00, so not to bad. don't believe it has a fuel pump.
    thanks

    wasn't sure about that either. I have had them for about 20 years, 4 of them and this is the first one i ever had trouble with. the first 2 i gave to my kids and they still use them and another one for our house in case of emergency. very happy with them. This one is i think my fault, i just got lazy and did not store it right.
  • Just blowing compressed air through the carb's orifices, jets, and barrel may not have eliminated your fuel problem. There is a good chance that the main jet is partially blocked. You could invest in some carb cleaner, disassemble the carb and clean it thoroughly. I use a gallon can of Berryman's and soak all metal parts for a few hours.

    Your easiest solution would be to buy a new carb and install it. If you later run into someone that will clean the carb or has the correct cleaner, you could service it and have a standby.

    I've used all the usual gas storage "snake oils", including red Stabil, and didn't notice too much difference other than Sea Foam tends to clean things better. Yes, filling the tank with the Stabilizer, to the top, will prevent oxidation of the gas in the tank.

    yes a new carb I think is the answer and for the price its probably the only way to go.
    thanks

    Try one more thing before scrapping your existing carb.

    Westend is on the right track, blowing air or cleaner through is often not enough to really clean the carb.

    Most Chinese clone engines use the same carb design as a Honda, this design IS prone to jet clogging.. Does not matter if you use stabilizer or what color of stabilizer or not, it WILL eventually clog.

    Additionally the float valve tends to stick shut after being stored for long periods of time.

    For the jet, you NEED to REMOVE the jet AND MIXING TUBE/ORIFICE. That IS where the clog is.

    Take a look at a YouTube video which shows how to properly disassemble and clean a Honda type carb..

    HONDA GX CARB CLEANING

    If you want more vids do a search for "cleaning Honda GX carbs".

    I would also suggest replacing the spark plug, most Chinese clone engines come with a real cheap plug, it WILL eventually quit firing and still look good.

    If you flooded the engine and the plug got wet, replace the plug, modern fuel tends to coat the plugs and short them out and cleaning them doesn't fix it either.
