It will probably make more sense if I explain why I use fuse wire.
In the image below I rubbed the copper fuse wire around the brass gas fitting with some force for at least 20 seconds and it did not even polish the tarnish off the brass so the jets are undamaged with this method.
What materials are fuse elements made from?
Most Low Voltage fuse elements are made of copper (Cu). Fuse elements of fast acting fuses and High Voltage fuses are primarily made of silver (Ag). Silver plated copper is also commonly used. As a rule, fuse elements of time delay fuses contain low melting point materials, e.g. tin (Sn) or zinc (Zn) and alloys thereof. Formerly used alloys containing lead (Pb) and cadmium (Cd) have widely been eliminated.
What materials are jets made from? Jets are fuel and air metering orifices. At least in most carburettors I�ve worked on they are made of brass and are screwed into suitable holes machined into the carb body.
A lot of manuals say don't go poking around jets,it's mainly so people don't force wire into the jet making the jet hole larger than the standard jet but when you have a brass jet and a copper wire plated in silver, I have never scratched a jet hole larger than standard when cleaning one in this way.
I use different amp size fuse wire for different sized jets in the image below this 8 amp wire looks to be about 10 thousands of an inch and should fit a lot of the smaller jets.
No kick-back nightmare when using a zip starter or drill and once the engine is running well you can fit the impulse starter back on if you prefer it,I just change the starter because it's quicker starting an old motor with the zip starter when you have a problem with the motor.
