If it’s still on points, then yes the accuspark is a good addition, just be careful with the routing of the cables under the dizzy cap, my last one was rubbing on the main shaft and caused the car to stop at a busy junction, not good.
The 123 system is what I replaced the accuspark with, which is handy for mapping to cope with this modern fuel we get these days..
I am not at my usual location right now, but I will trawl my attachments on here and send you all the Weber info I have, as @Robin Parker (Red Spider) - Yorkshire AO says they are really simple to work on, and what you can't work out we can help you with.
Also as @Chris Broster - Bristol & Bath AO quite rightly mentions, do replace all rubber fuel lines for an ethanol compliant type,
Finally don’t think any question is stupid, there are only stupid answers, so post away we are here to help 👍
