    I don't DO Facebook. Starters can Break small engines if they flood. My first engine. A FROG 150 Diesel ruined the fingers of Both hands before I mastered it. I didn't KNOW anyone else with engines. I designed and built my Own Control line Plane. IT didn't last very Long either, before it bit the dust. Not easy times. I was about 12. Nev

    He treated the exams as a Box ticking exercise which in some situations they are.. PLENTY of People recognised there WAS a Problem. HE CHOSE to remain ignorant of Essential Knowledge. Please read my LAST sentence above. Nev

    Pilot's like others, Can't KNOW what they DON'T KNOW. Flying is NOT forgiving of Mistakes, Carelessness or LACK of Knowledge. The Rules are written in BLOOD. Heed them. Stall training is Generally woefully Inadequate and in some aspects DANGEROUS. . Nev

    Probably the ONLY kind you will get. Hard to land in gusty winds.. Nev

    Depending on the Class of the Hold, being left in in one can be fatal.. Nev

    Grumman is the Manufacturer. Gulfstream is the Model and they are great stuff,. Nev

    Some CADMIUM Plating looked like Brass. Cadmium Plating has been Banned in some Places. Cadmium is dangerous The Alternative in Aviation is Zinc-Nickel. That's been the case for Many years Electroplaters have a hard time with EPA's. MOST have gone out of business. . Zinc gives Galvanic Protection. (sacrificial). But it is soft. Nev

    Seems like a LOT of Money. I thought some of the SAAA ones were dear. Nev

    The JOKERS are out early today. Nev

    No, I was referring to the damaged 747. Nev

    There's a Lot of ways of helping them Last Better. Gyros need Lots of Power. Carbon Behind the rings is a Killer. Big end Cages fail and the Hard skin flakes off the Crank Pins and the results of that are Quick and fast. Any Holey Piston Means aluminium all through that Cylinder and case. Nev

    The original Book may not be the Best reference, Currently. Nev

    BrenDAn, The MOTOR YOU Have had a reputation for breaking Crankshafts near the drive end. Nev

    I mentioned earlier that adding oil to fuel increases It's viscosity which makes it flow slower thus Leaning the Mixture/ THAT statement is NOT CORRECT as you point out.. I would suggest that they MEANT Oil Available to the engine. Way Back a Friend of mine riding a Bultaco at Mt Panorama put a foot operated oil pump on his bike to Prevent engine damage down conrod straight. A chain saw should require LOAD to make it fire evenly and it should be rich enough to never scream and do high revs. Nev

    Yes I wouldn't suggest over revving that Motor. Nev

    IF you were Interested, you'd have queried Blue Adventures Post, over 3 weeks ago.. Maybe. Nev

    EVEN fuel Distribution is the Prime method of getting efficiency, Injection is a good way of achieving it. . Nev

    Premix at Low or closed throttle does not lubricate the Motor adequately. That's well Understood. Going to full throttle is Not a common set up. Nev

    Anyone CAN CLAIM anything. A CV carb would ALWAYS have better atomisation across the RANGE. An oversize Slide Carb would be even worse. Hard to tune and little venturi effect.( suction) That type has NEVER been Known for good economy and there's good reasons for that Inherent in the design. Nev

    IF the Mix has less fuel there will be Unused Oxygen and that will try to oxidise other things like exhaust valves and also Burn slower, and less reliably. Ie May spit Back.. Nev

    Not a Lot of GOOD 2 strokes are Premix these days. Oil injection is the go. Adding more Oil Makes the fuel more Viscous and the Jetting Has to be altered. It won't compensate for Altitude either. Premix requires to run all the fuel out to prevent Left over oil thickening in the carbs when the Petrol evaporates. Nev

    Not radically different to many other slide Carburettors. Mikuni. Amal etc The only way to use less fuel is LEAN it out and that Melts/Burns holes in 2 stroke Pistons. This type of carburettor usually sets the standard for straight out Power with ONE per cylinder The difficulty providing richer Mixture when accelerating. Usually done by a well around the Needle Jet or making a Pumper version on some flat slide designs Parlticularly Snapping open a slide carb can usually Kill the Motor IF done quickly enough. Nev

    Have an adjustable shut off valve in the middle. Nev

    I' m just correcting a couple of errors. Nev
