    It's Pretty hard to Know when an Exhaust valve will Break. A loose fitting guide Can Cause it. OR just Fatigue. Nev

    IF I'd been forewarned I wouldn't have wasted 33 Minutes.. Nev

    Not really a LOT in that. Nev

    It's a Method used for Mainly Motorbikes in the Old days. It can also show whether the chosen Hot/Cold plug is the correct one. Performance (hot) Motors use COLD Plugs. Too HOT a Plug risks Pre-ignition. Nev

    General rule with Leaning (unless operating at a high altitude aerodrome) Don't lean till below 75% Power. Procedure...... Lean till the engine starts to run a bit rough, Correct it (make it smooth) and then richen a little bit. That way you will get the POH consumption figures. Most engines are rich at idle. and can soot plugs which can cause a Mag drop or Power loss. It's permissible to lean on taxi but have a way to ENSURE you go to full rich before take off Power is applied. AVAS has 2 octane ratings like 100/110 The higher one is for a RICH mixture. Nev

    Telling people to lean out the mixture to get Power on a 2 stroke is NOT something I would Put my name to. It's a good way to put a Hole in the Piston. That then requires a complete strip down. You May get More revs under Light Loads But IT really is a NO NO for Aircraft or Chainsaws. Nev

    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

    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
  23. facthunter
    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
