    How to get to BDC w/ pull start, and How important is After Run procedure?

    I like using my 30% Heli fuel in my LST2 with Spec 3. Lots of smoke.... seems like its providing good lube. The truck Hauls Assshnic!! No body does afterrun on heli's. Is it really that important? I've heard both! And what about Botom Dead Center with a pull start? Thats an other thing the heli guys dont do! And those engines perform hard and long and last forever!?!?!?!?!?!

    Take the plug out so you can see the piston and turn the motor with the flywheel and your finger or catch the ridges of the flywheel with a flat screw driver pretty important on the cool down to have it at BDC so you don't loose the pinch at the top.

    Take the plug out, or take off the manifold, and put the piston at BDC; then mark your flywheel with a marker at the bottom/top.. which ever you prefer, to let you know it's at BDC.

    yeah i do the marker thing and yes it is important ...if you let your mill chill at top dead center then the sleeve will not contract all the way and it will shorten engine life... i dont use after run every time just at the end of the day plus it helps promote easy starting besides it inhibits the formation of rust and all glow fuels attract moisture
    LST2, MLST2, Blade CX2, Cen Gen LE ... funny how all these are second generation

    Do you really think its even possible for a motor to stick at Top Dead Center? I don't see how that would even be possible. Seems to me you could just pull the pull start a couple of clicks and be fine

    RE: How to get to BDC w/ pull start, and How important is After Run procedure?

    comparing a heli engine
    and their needs
    to a car/truck engine
    and it's needs
    is, well, they really
    don't compare at all

    a heli engine is likely ringed
    won't have a need to store at bdc
    a car/truck engine is interference fit
    really should be stored at bdc

    a hei engine spins at what,
    about 20k - 22k rpm
    and a car/truck engine
    at 30k - 35k rpm

    a heli engine is more open
    with a big 'ol fan above it keeping it cool
    a car/truck engine is stuck inside
    a plastic body with minimal air flow

    a heli engine runs best on
    fuel with 18% oil

    car/truck engines run best
    on about 12% oil

    and no, more oil is
    not always better

    in other words
    quit treating that spec 3
    like a heli engine
    it's not
    it's a car/truck engine and
    you need to care for it as such
    two kinds of people i never believe - fanboys and haters
    they never tell the whole truth

    I wouldn't advise this but you could call everyone else a liar and stupid by oh making sure the piston was at TDC when done and let it cool there, not using ARO and report back at 8 gallons on how everything looks internally, pinch, and general running condition. I won't do that but you do what your gut tells you.

    Oh I'm chilled. Just seems like you and other posters sometimes ask a question and then seem to want to dispute the info returned. SEEMS is the key word and I don't know you from Adam so I just made a remark. It was not meant to be taken personally, like an attack on you, but if it was, well....[sm=shades_smile.gif]

    After Run oil = $3.... Thats $3 insurance for your engine. When the engine gets rusted out ( like the engine in the "I cant believe this engine still runs " post ) that $3 insurance is a drop of water in a glass compared to what its going to cost to get a new one

    I only use after run oil if my truck will sit for more than a week. I use trinity and they say you don't need it but I like the whole just in case thing.

    I use WD40 for my after run, cost like $2.00 and takes a few minutes. Took out the plug and marked the flywheel at BDC, also took only a few minutes and cost nothing. I say ...why not? cheap fast and easy, may pay off in the long run.
