 Guy's I have a Tiger 60 in a T/F Score that runs like a bear, however gettin it started is a whole nother matter...  It is broken in and runs well when I get it started, however that is the problem. I choke it and prime it as well as apply an electric starter, and it spins and spins then finally starts.
 I am at my wits end as to why?  I am usin Powermaster 5% nitro in like all my other engines, but this one just doesn't want to start..
  I sure could use some suggestions...  T I A

Does it really have good compression?  You may also try a different plug, or like one of my Fox 15's, flood it to start.  Each engine has it own character, even in same brand and size.  By the way if engine is inverted, which I think the Score is.  Turn the plane over before starting or even fueling the tank.  Prime the engine and flip the prop.  If it flips real easy, then hook up the battery and see if you get a bump.  If so flip it and it should start and run the prime out.  Then I usually prime again and start it again.  Then turn the plane over, fill the tank, make sure fuel is to needle valve, hook up battery and see if you get a bump.  If it bumps it should start fairly easy.  My method I learned from someone else.  Thanks Bigiron.  Have fun,  DOC Holliday

My guess is that you aren't getting any fuel into the engine. I would only partially choke the engine when flipping it. A little air needs to get through to pull fuelup into the crankcase. Just take care that it doesn't start up on you.
The other option is to turn the plane over, choke the venturi, and give one flip at most. You don't want too much fuel in the crankcase. Then turn back over and start it with wheels on ground.

  Guy's The compresson is excellent when I flip the prop it REALLY Snaps !!  I had Frank Bowman put a ring in it not too long ago and I have run it on the bench approx 1 hr then into the model. The glo driver lights the plug (Thunderbolt idle bar) like the Sun..I'll try holding it inverted and see if I get fuel to the venturi. As I said I'm at my wits end as this engine runes real well...When I can get it started...
  I"ppreciate the help and please keep the suggestions coming...
 Thanks again, Bootlegger

I'm a big believer in an air filter, and starting the engine inverted (on the wheels). Choke it or put a squirt of fuel on the air filter, set it down, and hit the starter button. Use some old panty hose if you must, or a Bruline, your choice. I haven't seen anyplace where you pulled the prop through and got a 'bump', tho. If you can get a consistent 'bump' after your 'drill', just flip it, or hit it with the starter. I don't like flippin' 3 bladers, tho. Steve

  Talked to Marvin Denny last evenin and he suggested checkin the back plate bolts, did so and they are tight as are the head bolts.. Pulled the entire package, Tank and engine, and will install on the bench and try there.
 When I find out what it is I'll post here to share the info...

 Put engine and tank on the bench, 1st run choked one time, back flipped and away it went, 2nd & 3rd runs didn't choke it just fliped and away it went...
 Will re-install and see what happens...Will keep ya'll posted...

Gil,

While out flying Monday, Dave's brand new set up was giving us fits.  A new LA 40 in a Noblarf.  We finally the cowl and finally found a hairline spilt in the fuel line.  Fixed that and he was in the air!  Before, it would just flood and never fire, but we finally got it running.  I turned the needle all the way out and it never richened up......  that was when I saw the split in the line.  Still do not fully understand it all, but it was no further problem.  We had been OVER priming it, flooding it, and it just wasn't drawing fuel on its own all along.

     Mornin, Bill The blind hog found an acorn, we turned the test stand inverted on some saw horses and when we fueled the tank, fuel ran out the venturi. When I start to fuel with everything back in the plane, I'll use hemostats to pinch the fuel line off and prevent this problem. Oh, the we is Nick Liuzza and I..
  Wanted to make this post so that if someone had the same problem, maybe this would help...
 Again I thank all ya'll for all the suggestions...
