[QUOTE="PurplePackFan, post: 185646, member: 9909"] Well first of all, thanks for all the input. I ended up sanding/cleaning points and re-gapping them. No luck. Now I have no sparke at all. I decided to pull the head and have the valve seats ground and valves matched at machine shop to make them right. That will take a couple weeks to get them back. Now I am looking at going with a CDI ignition. I did some searching here on the forum and some have used the kit from "xrarespares" on ebay. Is this kit any good?

Any feedback is welcome. Which do you guys recommend? I am tired of dealing with 50 year old points ignition. Also, with the big bore kit, how should the carb be jetted? Should I increase the main jet size? I have some in stock just in case. I also ordered the heat insulator for the carb. Looking forward to your feedback. John [/QUOTE]
