Well i hope this thread doesn't get nasty! Bought an A+ 1380 from Sydney off ebay for a good price-not complaining, has a weber with 5"manifold, extractors and exhaust, RE13, headwork, lsd etc etc.
Would have liked to build up an engine myself, but time and finances were against me so i snapped it up. Owner had claimed it had been dynoed and tuned.
Alarm bells started ringing when i found 40mm diameter ram tubes fitted to a 45mm weber. Fixed that easily. Tidied up many other similar silly things, painted it, set tappets, put points in it, ran it on floor and set timing as recommended by owner for "recurved" dizzy.
Put it in car, drove around, went quite well but seemed a bit flat. Checked air/ fuel ratio-10.5 A/F ratio under load. Mucked around with jets etc- got a nice 12.5:1 A/F ratio- better but still flat.
MMM better look at that timing again....Hello! NO centrifical advance!! That explains flatness i guess, dizzy must be seized. Pulled it out to unseize-found it had been welded up!!

Might be alright for a methanol blown engine- but not this baby!!
I reckon the dyno guy has left his locked test dizzy in there and forgotton about it! Either that or he may just be a rough operator!!!
Want to do pulsar dizzy conversion but until then i've cut weights free and cleaned it up, will put back in and i'm tipping it may go a LOT better. (And yes i will recheck those mixtures)
Yes i know, i know, i should have checked that it advanced the first time, don't know why i didn't!!! Brain fade i guess.
