I have a complete engine I bought to convert, but have since acquired another already modified.

I can twin plug the heads for you

Inspector, 161 John Whiting. I believe he built one if not two of them

I have an EFS 3 throttle body. Unused and unfitted.
I would like to swap it for an EFS 2.

Thanks phil.

I have an EFS3A unused. £800 if it will do. I understand they will function at less than 85HP with some fiddling.

I would think it's not difficult to do provided you can obtain the design drawings. Any old school engineering machine shop could do it, mine included.

You would probably need at least a part inspection and that would require the sanction of the LAA.
I had to fly to France to do inspect a cub prior to it being flown back to the UK.

Ask Malcolm Mcbride for advice.

Well I had to repair 1050 and got the drawings of th area I needed no problem from Pete.

Sorry if I am too late with the reply.

Pete smoothy has them.

If you are not sorted, I think I have one I used on a Jodel leg to pin the aerofoil shaped slider.

My experience of flying my 582 Kitfox is that properly installed maintained and checked, they will give little problems. I have 1000 + Hrs mostly on 2 strokes with no great issues except for those caused by fuel starvation or ignition faults on the early points engines. I have worked on many of the ...

I have done a few and have all the gear to do it.

I guess you will also require the barrel register increasing?

If you are not sorted, give me a ring

Has anyone attempted this as I am about build a 2.3 litre flywheel drive engine for my Kitfox.

I am researching interference fit's etc, so any suggestions would be welcome.

As I recall the BSA gold stars had ali barrels with cast iron, meehanite or ductile iron liners, so not impossible.

When I used to layup polyester on styrofoam, I used to seal the plug with PVA glue. This was for RC models and so quite small parts by comparison with GA.
However. You wont find a better explanation than that in Tony Bingelis's Sportplane Construction Techniques. ( Available from the LAA ! )
