Years ago, all I had was mag type gassers. I had mostly Sacks but also had Huskies and Zenoahs. My procedure was much the same as with the Electronic engines I have now. Always started them by hand (except my hard starting Tarus[>:]) After all preflight and radio checks, and the plane tied down or held:

Choke on
switch on
full throttle
glove on
smack through compression till it fires and chokes out (usually 3-5 turns)
choke off
throttle to idle
smack through compression till it fires again and idles. (usually 3 or 4 turns)

Most of these engines like to be fairly wet to start.
