    Please post back if the valve adjustment on the one side made any difference. Hopefully you found the cause of your cold start issue. If not, I would be on the phone with B&S Corporate.

    Ya know, the ACR ( auto. comp. release ) is totally dependent on the valves being adjusted correctly, right? Too loose and the ACR ain't gonna do it's job.
    Hopefully, yer adjustment corrects it.

    Ed, post back your sons opinion, good or bad. I gave up my heavy jump pack for the NOCO and have not had any issues.

    A friend of mine has/had one. It works well, but it will try to deliver more than it's capacity, he tried jumping off a Duramax with it. It started it, but it fried it too...

    Don't discount a hydraulic load as part of the problem. I've got a couple Vangard powered units that, as the temp gets low, will not start without the addition of a charger and a toot of starting fluid, or disconnecting the hydraulics till the engine's warmed up.

    The guy at Grasshopper mentioned unloading the hydraulics to help out.

    Seems yer main dilemma is yer dealer is a moron. (See quote #3 ) Ain't the unit under warranty? Engine problems/warranty can be handled by any authorized B&S dealer

    #2
    Look, there is no hydraulic load, nada.

    #3
    Unloading the hydraulics...now that's a goodun'!
    Did the clown at grassidiots explain how , exactly, yer supposed to "unload" the hydraulics ???
    Bunch of B.S., is all.

    I have some walkbehinds that are pull start that you can take the tension off the hydros to start. Never had to do it. Not familiar with the grasshoppers though...I’m guessing your issue is fixed with the valve adjustment.

    Hasn't been cold enough since the valve adjustment, don't know. I can tell you one thing however, this thing has the flimsiest, cheapest rocker arms in the history of commercial engines. I have checked them on my Kawasaki's which in their history only one engine, one time, needed adjusting, that Kawi has far superior valve-train components. I can see this mower getting re-powered in the future, and Vanguards are going to permanently vacate my fleet.
