I've managed to aquire a second carb fir my 5, my original carb is in working order and is running about 10-12 psi. The new carb is a group A jobbie but I'm unsure if it works and what jets etc it has.
I'm looking to rebuild one if them to run possibly 16-20 psi with a new carb kit off the Rtoc shop and new jets etc, which one should I use??
