    Thanks for the info, Valk.
    I've looked at that link before. It's pretty accurate but doesn't include one other station in town that carries ethanol free gas. Maybe I should tell my cousin he needs to add his station to the list.

    Just a quick update: I tried to start the mower this afternoon and all it would do is fire up for maybe 2 seconds and then die. Crank on it a few more times and it would do it again. After about 3 times, I just said the heck with. Maybe I'll have more time to mess with it this weekend.

    How many hours on it? How to test the coils?

    It's got less than 300 hours on it.

    Searched on FH721 and got info on coil resistance and valve adjustment from "Restrorob". I need to do this once I charge the batteries and get it moving. I barely finished out the season last year, I have 1500 hrs on mine but never adjusted anything yet. I guess I'm paying for it now. Sounds like similar problem, but mine would eventually run for a few hours then stop again.

    Air gap on the coils. Valve gap. And plugs and ohm the coils

    Well, with little to no time to work on my mower and about as much knowlege on what it might take to fix it, I relented and took it to the repair shop.
    Hopefully the cooler weather next week will keep the grass/weeds in my yard from growing much more, and hopefully my mower will be repaired soon. Otherwise, I'm going to have to use my bush hog rather than a mower.
    My neighbor is picking up his new Hustler today... maybe he would like to offer me a demo on my jungle of a yard.

    Since the shop has had my mower for a few days, I stopped by at lunch to check on it. The tech said it had him pretty stumped. Seems the mower is flooding pretty bad (which I told them it was doing when I dropped it off). His first guess was that it was a carb issue, but he's had the carb apart twice and said that it looked very clean. There are a couple of updated carb parts, so he ordered those to try, and told me to check back sometime next week.
    Looks like I may need to borrow my neighbors new Hustler.

    To put this thread to bed, I got my mower back yesterday. New o-ring and a new float in the carb and the ol' Kawasaki was back to running fine. I mowed for about an hour yesterday evening and plan to put in about that much more time today.
    Then it'll be time to clean the clumpy spring grass from under the deck and put some sharp blades on there and get ready for my regular lawn grass.

    I had a 23 HP engine that had the smallest amount of gue on the float bowl needle valve that wouldn't let it close all the way. So it would run ok for a minute and then as the pump forced gas passed the partially closed valve, it would run rich and eventually flood out. This might be why yours ran better when you turn the gas off. Glad you figured it out.
