Hi Does any know how good the merlin gas tank and burner is for mamods?, I have just brought one on ebay complete with a sl1 and don't know anything about them.

Dont unscrew them all the way, the come out and go bang. Thats all i know as somone on another forum done just that.

That sounds bad but I don't intend taking it apart providing it works

Yeah this is the gas controll valve.

Do you know how much you can turn them without the bang?

No sorry.. I shouldnt think youd need to take it out very far at all given the size of the mamod boiler.

sorry i cant be of more help :

I wouldnt want to go more than a full turn. there are two 'o' rings on the gas regulator shaft, take it past these and...'BOOM'. these go brittle in time and gas leaks back down the reg shaft.

Thanks at least I know what not to do now.

I took my new engine to the local 16mm association meet got it looked over then ran it on the test track for the first time. It runs reallly well and is very controlable

Now I need to leter and name it.

Any pictures mate?

She (or it for the politically correct) was built on 01 APR 1981 according to the box and the gas burner was supplied from merlin in 1982. I took her to the local 16mm association meeting where she was tested on the track. The run was great very controlable  and no problems so I'm very happy with this ebay find. Upgrades I intend are 25 psi valve, heat shield for control arm and lettering for WSPR.

 The Name will be Blodwyn after one of the fire breathing dragons on "Ivor the engine"

Lettering done and a few minor mods

I need to replace the gause on the burner it needs to be 80 mm x35 mm Goes anyone have some ?
