Following up on an earlier post, i decided to go with the Power Arc C5 optical ignition system for E2241. After studying the various magnetic electronic ignition systems compared to the C5, i decided on the C5. I've got quick cold starts w/ minimal choke, brief warm ups, immediate smooth idle, steady acceleration throughout the rpm range. Super easy to install. I'm really pleased with the results.
Paul Crowe of C5,
