Cox,

If your Brodak is the same as the AME .8 I have, it could be the head. Mine had the strangest head arrangement I've ever seen.

Change it for a Cox head & try again, mine worked after a fashion with a Cox 049 head, but even better with a proper 1/2 A head and clamp ring from Tower.

Is it a MK I or MK II?

The Brodak MK II has a head design completely different from NORVEL and COX. It's a 3 screw head that uses a standard plug. The COX and NORVEL heads are screw in heads.

Mine as I said is a AME .08, whether that is a Brodak Mk1 or 11 I don't know but a Cox head is a direct fit into it.

The AME .8 is a NORVEL product; the Brodak MK II is manufactured by a different company for John Brodak, a US based supplier for control line planes, engines and accessories.

Both engines are of eastern European origin, but from different parts of the eastern bloc.

Cox,

Is your motor in a plane or on a test bench?

What fuel are you using? Battery properly charged?

Give us some more details about your set up & we'll be in a better position to answer you.

hmmmm , a good place to start is the right amount of prime ...

To rich [ to much fuel ] and it will just bite [ prop bounces back at you when engine fires ]

To lean and it might just pop a little ...

Get the prime right = Count drops ..

Once you get it to fire and rev out for a second or two , connect your fuel ..
Are you using pressure [ bladder ] or suction ?
