    Oooops - Steve you beat me to it!  Sorry for the duplication.
    Yes, I was real happy to hear Harvey rave about the ASP 61.
    He sees no real performance difference than an OS FSR series
    engine, as far as starting, power and carburetor performance.
    It turned a 12X6 prop at 11.5K RPMs and it idled nicely down
    well below 2K RPM with a standard Fox idlebar plug. He said mid
    range performance looked good too.  He chopped his finger up
    pretty good with it, I guess the test stand started falling over
    and it bit him as he tried to catch it, or something like that.
    
    He suggested one thing eliminate the tight barrel on the carburetor
    (it comes very tight and would make the throttle servo/pushrod
    work pretty hard).  He cut two to three turns off the spring that
    puts the tension on the barrel (to keep it pushed outward).  He
    had his engine with him today and the barrel movement felt much
    better.
    
    Again, it's not your top of the line engine but looks like a good
    sport engine.  I'll be interested to see how the bearings etc
    hold up.  Worth a try for $75!  Maybe I should have put this in
    the engine note.
    
    I'm putting mine in a .60 size Beechcraft Bonanza (V-tail) I've been
    slowly working on and hope to finish this winter.  My dad owns a
    full-scale version and I thought he'd get a real kick out of my scale
    version.  It'll have cheapo mechanical retracts and not a great deal
    of attention to scale detail, but it'll be fun to see his reaction.
    This engine sounds like a perfect fit for the plane.

I had several Enya .35 CL engines from my CL days and I've successfully 
converted 2 of them. Just order the Enya carb subassembly and remove the 
CL needle valve assembly and venturi insert and bolt in the carb. They
are nice, solid engines with a long life. I've bent a few but not worn 
one out! (and they used to be cheap enough to put one on each CL plane 
I had ;*)

    I recently bought a supertiger .35 and the carburetor
    has the leters NS on the front.
    Does anyone know the maker and where I can purchase
    parts for it?  In southern N.H. or northern Mass.

    John,
    
    The letters "NS" don't bring anything instantly to mind.  Are you sure
    it's an after-market carb?  Can you describe it for us??  That might
    help pin it down.

        It looks like a Perry, from what I can see from pictures in
    the Tower cat. with the low speed adjust on the top.
    
    John
    

    John,
    
    The screw you refer to "on the top," could this be the idle-stop screw,
    the one that adjusts how far the carb barrel is allowed to close (and
    also retains the barrel from falling out)?  The idle-mixture adjustment
    should be located on either the right or (in the case of a Perry) left
    side of the carb (when viewed from the back of the engine looking
    forward).  On the Perry, the idle-mixture adjust is a large (~3/8"
    dia.), serrated-edged disc located flat against the left side of the
    black, filled-epoxy carb body.  The high speed needle emanates from the
    center of the idle-mixture disc and is extremely short...just right for
    getting yer' knuckles in the prop while tuning the top end.   Does any
    or all of this sounds familiar?  If so, you've got a Perry there but I
    couldn't guess what the "NS" means.

    I'll take a better look at it tonight, and try to give a better
    description tomorrow.

    The body of the carb is not black epoxy, but aluminum.
    There is no idle adjusting screw anywhere, and the screw on
    to IS the barrel screw.  One thing i noticed that is different
    from my OS and K&B is that the barrel when opened and closed, 
    also slides in and out a small amount (approx 1/4").
    
    John
    

Kavan made replacement carbs like Perry way back when. I've got one for a Super 
Tiger still in the box. It has an aluminum body...

That sounds like the carb on my Super Tiger .15, and also like
the one on my Fox .36.  The idle stop screw projects into a
spiral groove cut in the barrel.  When the barrel is turned, the
screw in the groove forces the barrel to slide in and out.

Fuel for the idle jet comes, near as I can see, past the main
needle valve and into the hole set by the idle needle -- when the
engine is running above idle the the idle needle has been pulled
out of the circuit by the sliding action of the barrel.

    John,
    
    Hmmmmmm, well that about does it fer' guessin'...I haven't another clue
    as to what carb it might be.  The sliding in-out action of the barrel
    was/is common to several stock and after-market makes so it's a toss-up
    as to what it might be.  BTW, there HAS to be an idle adjust of some
    sort, somewhere.  _MUCH_ older tech. carbs simply had an air-bleed
    screw mounted [usually] in the upper/left corner of the face of the
    carb body (when viewed from the front looking aft.  This quite simply
    gave you rough control of the air-to-fuel mixture at idle.  The newer
    breed of carbs all (except Perry) use a secondary needle to control
    mixture and the adjustment is normally a small, flush screw, generally
    on the side where the throttle arm is located (opposite from the needle
    valve).
    
    I'm sorry we haven't been able to identify the carb for you but let me
    ask again; are you _sure_ this is an after-market and not a stock Super
    Tigre carb??  S.T. carbs are normally distinguished by having an obvious
    casting rather than the much more common machined body (lots more curves 
    and a casting flash line running front-to-rear through the carb center-
    line) and by having a rather long needle-valve, simply bent 90-degrees at 
    the end and _very_ fine threads such that large movements of the needle 
    result in small changes in setting.  Even if this is the case, I still
    have no ide what the "NS" might indicate.

non-Schnurle (how's it spelled??) since the fuel demands between a ported and 
non-ported engine would vary greatly...

    Re: .-1, Jim,
    
    Yeah, that thought'd occurred to me and it certainly could be that "NS"
    means "non-Schnuerle" but it doesn't help me try to pin down the maker
    of the carb unless, as I'm currently pursuing, the carb is, indeed, a
    stock Super Tigre item.  Maybe we'll know when John responds to my
    latest question(s).  I'm leaning towards it being a stock carb with, as
    you suggest, a factory code (NS) denoting non-Schnuerle.  If this be
    the case, then John's problem is a non-problem as he can get parts
    through Super Tigre's distributor (isn't that World Engines?).

    re:.12
    
    Al,
    The problem is that the carb has no needle valve, that is the part
    that i need. But I had a COMO engine and the throttle adjustment
    is nothing like it. The como is the same as a stock supertiger.
    It could be a cast housing, since the barrel housing is round
    and the only thing that is square is where the letters N.S. is.
    I have the carb with me today to take it to a local hobbie shop.
    don't know if they will be much help, they have more car stuff
    than anything else.
