    hello ...sorry for dragging up an old thread...but i just aquired a used honda eb 2500 generator with a gx 160 on it... i was going over it,cleaning it up and what not...i popped the valve cover off at at tdc the rocker arms seem very loose..i can wiggle them side to side(not in the valve/pushrod direction but 90 degrees on the mounting stud) quite a bit im going to check the valve clearance today but is that normal if out of adjustment...or could something be badly worn?...it starts right up first "lazy pull" and runs well...so i cant imagine they are "way out of adj.....thanks in advance!

    It's normal for them to seem loose, You just don't want too much up/down movement which would indicate needing adjustment.

    cool thank you...i checked the clearances.. exhaust was spot on intake slightly out of spec so i adjusted it....and i also pulled out the plug to replace only to find the previous owner had appearanly went to walmart and grabbed a champion mower plug..the short one..cj14?...:hammerhead: hahaha could this have caused any damage to the motor?

    good to hear it wouldnt have caused a problem....thanks yes thats what i replaced it with....and the final issue i found was the gfci duplex works in that it supplies power..but when hitting the test button it doesnt trip out..

    so i was looking into replacing it but honda wants over $100 for it...looking at it.. it appears to me to just be a 20a gfci duplex recepticle that i can buy at home depot for $15 ...do you know if it is really a special item i need to buy from honda?..the honda dealer told me when i asked the same question...."oh yeah you definately need to used the honda replacement one...if you dont youre going to loose power...as well as the generator will be alot louder"....i could be wrong but i dont see how either is possible as long as i use a commercial grade 20a gfci outlet...can you confirm eith way on this?...thanks so much for all your help!!:drinkup:

    OkAY i AM A LITTLE CONFUSED ON THIS QUESTION.
    It has nothing to do with a gas engine.
    So maybe this is a generator that has a gfci to protect the load circuits on the outlets?

    A GFCI is a ground fault circuit interrupter.
    So the first question is the gfci a 240 volt device or a 120 volt device.
    But to be more specific is it a 240/120 device or is it a straight 120 or straight 240 device. There is a big deference.
    Maybe you need to state the model number and what this machine is.

    Ruben, This is a Honda EB2500 Generator, It puts out 120 only no 240.

    Here's a EB2500 control panel, It may not be correct since the spec and serial numbers were not posted but gives a idea of the set-up;

    It's got a 120 V twist lock receptacle #10 and the gfci receptacle #9.

    To answer the question of paying close to 100 bux for a Honda receptacle, I wouldn't.

    I have replaced regular non gfci receptacles in Homelite and other brand gen-sets in the past with household receptacles costing less than 75 cent but not a Honda.

    What you have to watch for is the break-off legs between the wire lug/screws on the receptacle that tie those two lugs/screws together on each side. Look at the old receptacle and see which legs are broke off and break off the same legs on the new receptacle.

    If a house gfci receptacle from the Depot will physically fit in the control panel there no reason to pay Honda 100 bux for one.
