    Called a kick starter because it looks like one? :banghead:

    My 74 250 will start very easily with a push, but won't start on the lever!!! not even when hot :thumbsdown:

    Is there a drill, like with older 4 strokes?

    I've tried rapid prodding, copious flooding, no flooding and single kicks from TDC, all to no avail :excuseme:

    The bike has had all new bearings and seals throughout along with a rod kit, re-bore and a new Wiseco piston. It has a good spark and runs well once lit.

    Does anyone else have the same problem?

    Here's a old thread reply from another Husky Forum i kept with
    a similiar starting problem. Author was Dave Byland

    Dave's 501 Maico method works for all my big bore Huskys
    (read below)


    Sounds like you have a factory fresh Husky. :) Seriously, this is
    very common. The primary difference between the Husky and virtually
    all Japanese off road bikes (and maybe all other bikes period) is
    how fast you can spin the motor with the kick starter. I'll bet you
    can push your 360 ten feet and bump start it, and it seems almost
    instantenous. Husky kick start design makes it very hard to make
    the motor spin more than one revolution. Since it's a '76 360, you
    have either the "bent" kick lever (like you heated up the lever and
    bent it forward) or the first of the pretzel levers. Marginal
    improvements, but better than the original short / straight lever,
    as used from late 60's through 75. Ignitions don't generally
    produce their hottest spark at minimum rpm, nor do piston port or
    reed valved engines produce their hardest "suck" of air / fuel
    mixture at the speed of "barely moving".

    Timing 3 degrees btdc? I might be wrong, but you ought to check
    your manual again...seems like 18-22 degrees btdc (depending on the
    model and modifications) is more like it. At 3 degrees, you'd be
    trying to fire the fuel / air mix awfully late....but that ought to
    make it start easier, not harder. Won't run worth a crap tho..

    Solutions? A shot of starting fluid helps, but it's kind of tedious
    taking the plug out to shoot a squirt in the plug hole, reinstall
    the plug and then kick it. New mikuni carb with a richer starting
    circuit? Nope. PVL ignition? Uh uh. Dynamite? Sometimes you
    feel like resorting to that, but all that will do is END the
    problem. You gotta kick the starter fast (but not necessarily hard)
    and frequently.. .like as quick as you can. Not so hard to do with a
    125, but progressively more breath-taking as the cylinder size goes
    up. As a 54 year-old 450 rider, I can attest to the necessity of
    learning how to do this really well, cause after about 6 kicks I
    have to stop, breath oxygen, take a nap, take a leak and have a few
    gulps of water before I can do it again. Some things that can help
    (other than timing being spot on, carb float level set correctly,
    good compression, no air leaks, new plug, good reeds, etc) are: If
    using a Bing, lean the bike over to the left a bit while you tickle
    it...maybe even shake the bike back & forth while tickling...and as
    soon as you're getting a good dribble from the overflow, turn the
    petcock off (this should result in getting a little fuel in the carb
    throat). Kick the beast 2-3 times rather quickly, and then give it
    a good fast kick with about 1/4 throttle. Usually works. I learned
    this from a Maico 501 rider who swore by Bing carbs with his reed
    valve setup! If using mikuni, turn the petcock on, turn the choke
    on, put the bike in maybe 3rd gear and rock it back and forth for
    about 60 seconds (makes the piston go up & down a bit and kind of
    helps get a little fuel / air charge in the cylinder). Then, turn
    the petcock off, NO THROTTLE, and kick, kick, kickety kick. Of
    course, if these methods don't work, remember to always unload your
    bike at the top of a small hill. :)

    One other thing I've read is that some Husky's have a minor
    interference problem between the ridges on the underside of the head
    and the top of the cylinder, which prevents a good seal when the
    motor is cold. The '75 - '76 360's have a problem with the cylinder
    liner being pushed a little off if you torque the head down too far
    above spec, and could create this problem. Once running, the
    temperature produces enough expansion to close up the leak. This
    can indeed cause very hard starting, but once running things seem
    fine. You can test to see if you're getting a good seal by using a
    piece of carbon paper between the head and cylinder...tighten the
    bolts, and then take them off and remove the head. There should be
    a carbon trace all the way around the seal area of the head and the
    top of the cylinder. If not, there's your problem. (There's lots of
    other methods to do this...but I'm a simple, old fashioned guy). I
    haven't personally experienced this on a Husky, but I did see this
    on an extensively modified Yamaha (came from turning the head to
    increase compression, but didn't catch that part of the head came in
    contact with a rib on a cylinder fin...). There are also stories
    about folks who have grafted on modern compression releases, primer
    pumps from jet skis, etc. to find the elusive way to start a Husky
    easily. Haven't read about anyone installing one of those electric
    start things tho....at least, not yet!


    Like i said Dave's rocking method works on my big bore Huskys &
    i find kicking my 250 fast works too.

    :shocked::shocked::shocked: wow, thanks for that, I haven't tried the rocking method since my 85 KTM 500 got nicked in the early 90's, forgot all about that one.

    I'll let you know how I get on :thumbsup:

    Check your Clutch. Take all the plates out,make certain there are not stuck together.
    Reassemble clutch. Adjust as per the factory at the clutch using the adjusting screw.
    7 - 11mm of play at actuating lever on the engine. My 74 Mag 250 would not start after sitting for a long time and this was the cause.

    Fitted a kicker from my friends 76 today, started with a couple of prods :applause:

    Seems that the - '75 starters are ornaments...

    Does anyone here have a spare 76 starter they'd be willing to sell, or should I just bend mine?

    MAG250, I understand what you're saying regarding the clutch, my friends 76 sometimes slips on the starter, making it hard to get over the compression stroke with any authority :thumbsup:

    Thanks for the advice fellas :cheers:

    Great post John!
    Have you or anyone else ever tried a TM flat side carb on the air cooled 430`s?

    Thanks,
