Pete,
"Karma"; Today I saw a Fuel Injection set up for sale and it probably was from a 2180 Miget or larger engine. It had the Fuel Injection Assembly and Ignition System (Mallory Mag)
"Nozel's, Plumbing, Maifolds, Air Cleaners and Ignition System.
If you are mechanical you might find it "Affordable", it't in Fresno, California.
"Speed Unlimited" on Belmont Avenue - "Ask for Ron"
Ask for Ron.
If it were me I'd go for a "Set of Webers" but you may not be me!
Good Luck,
Jack Blake
