You can try to use a super bonding agent with filler such as 'Q-BOND superglue kit' which is normally sold in many auto shops and can also be found on Ebay: it is not an ordinary superglue and is commonly used to repair difficult plastic and metal parts.
Q-bond also has a very long shelf life even after opening the container as it is almost pure superglue!
Hope it helps.

The rating in milliamps is a matter of battery capacity and charging rates. The higher the better as you will get more flashes per charge as long as you have the correct charger to match the batteries’ capacity and use the correct charging times. Aside from this issue of duty cycle between charges- this has no effect on the power of the flash unit as to output. This cant burn out or damage the circuitry.
The issue here is VOLTAGE. Most AA alkaline batteries provide 1.5 volts. Most rechargeable AAs provide 1.2 volts. We are looking at a voltage differential of 1.2 volts (a 20% deficit) if 4 batteries are required. This MAY cause slower recycling times in order to attain a full charge for each shot. In SOME units that can cause a bit if overheating due to strain on the step up circuitry.
It so best to check with the manufacture or distributor of you flash unit before purchasing you rechargeable batteries and charger. If you units have a built in charging circuit this can definitely be problems if there is a mismatch in charging rates and voltage. If this is the case be sire to check your manual or with the manufacturer or distributor- there must be a list of compatible batteries.

is your master flash set on a camera? The EX II has something that makes it have a 1 second delay when using sync mode, unless the master flash is set on the camera.

The grinding noise is the zoom head trying to match the focal length of your lens. A brand new one should NOT grind. It should be silent. It sounds like you got the one that fell off the pallet during shipping. Exchange it for another one.

Send the flash back to canon for Service this is not something that can be fixed in this forum. Do not use the flash the burning smell indicated a potentially dangerous problem and fire hazard.
