Re: Silver Solder question
Don't confuse 'silver solder' with 'soft solder'. Silver solder typically is a high temperature brazing alloy that requires much more heat than you'll ever want or need to solder carburetor jets or ignition wiring. Many people incorrectly call soft solder, silver solder becuae it is silver in color. They aren't the same animal.
I've successfully used 60/40 lead based solder as well as 50/50 for jets using an electric soldering gun. Same for ignition wiring splices. You'll get two schools of thought on flux core verses solid core solder. I'm one who uses solid core and paste flux. Some prefer the flux in the solder. Whatever spins your crank and works for you.
