Over priming, or some issue in the carburetor itself.

That much flame is not a normal thing.

No its normal starting.

You have the flame colour about right for initial start up but probably to fast in engine speed, slower start to run up.

I've seen a few of these engines start up

1. Lazy/slow red/yellow flame from fuel primed start up.

2. Blue smoke clearing cylinders with yellow flames to brown/grey smoke.

3. Blue with yellow tips on engine run up and under run.

4. Shut down black/grey exhaust smoke short burst.

If I can find some of my video will e-mail it.

While I do agree that the initial engine startup (flames) is too fast, as for the rest - the engine flames should behave depending on how we use the engine. Different mixtures and priming should effect how the flames look (color and volume). Not to mention the overall effects that different usage will have on the engine, like shown in the videos.

You know Alpha, in all the times I've seen Merlins start up, on Hurris, Spits, and P51s, and a Lancaster, I've never, ever seen a stack fire. Not one. I know it happens but it is far from normal and not a common thing.

Can we agree that it should not happen at every start up?

I know that there are those that would like to see it every time, and they would be wrong.

Every time I've seen Merlins start from cold they have the lazy flame effect from priming.

Some times depending on the lighting conditions you wont see too much of this effect, the camera though does see it very well.

I'm fortunate to be a member of FOD (Duxford) so I practically lived there a few years ago and saw a lot of aircraft in preparation for shows and being started for testing etc etc, Merlins especially as there are so many of them at Duxford
