Status: offline 		I have a 45 GX that I bought just over 2 years ago. The EI unit has gone bad. I want to put the newer EI unit (from the GX2) on it. What other steps do I need to take besides changing the prop hub and going to a Li-Po battery?

Thanks

Can you tell me where I could find a 14 mm to 10 mm reducer? I just get blank stares when I ask at the auto parts stores here. LOL.

Also, if I can't go that route. How hard will it be to change out the actual cap?

Thanks

Status: offline 		MVVS has reducers, and I made a couple myself. Still have two available, made from original UR17 spark plugs.
I know of some ignitions, that are/were extremely sensitive to changes to the high voltage cirquit, and are not to be messed with. The completely earth encased modern ignitions can play havoc with changes, so I am reluctant to answer unless backed up by experience. (none this moment, I fear)
Having said this, I have no idea how much tampering the MSR ICU ignition will allow.

Status: offline 		On a differnet tangent, is there an ignition unit to replace my GX2's? I am tired of having the engine backfire every time the ignition is powered on. It gets alot of looks and I dont particularly like having to explain the spark fire sequence. I dont flood my engines and dont like the feature(for me). Not a fan of having to clock the prop before I turn it on either.

Status: offline 		You can turn the feature Off by setting a jumper???
BTW
It is not a bad habot to set the prop in bottom position when the plane is idle. For inverted engines, it has the advantage, that the carb will not pump when moving the prop a little. If you bump the prop to compression to and fro, it will activate the carb and get some mixture pumped into the engine, so you do not neet the choke to start first flip.

Status: offline 		Pe,

Would it be possible for me to purchase one of those reducers from you? I am having a very difficult time locating one from the LHS here.

If I DID decide to replace the cylinder head, would I need to go through the break-in procedure again? Would I need to replace the ring on the piston?

Thanks

Remove the jumper next to the power cable. (if you have ignition V2). I am not sure if V1 can disable battery test.
You can download the ignition manuals from my web pages (left bar, gas engines, waaaay down)
or

Yes, you can. These items are not available from LHS's
When the engine has run not too much, there is no need to replace the piston ring. It will set soon enough to the new cylinder.
