  1. its going but a bit dormant at the moment unfortunately ! I will probably be selling it soon to make way for a new project tbh.

    and yeah I know what you mean about the technical mags they are always interesting!

  2. so I put a timing light on my fiat twin cam, and I assumed it would be timed off the marks that are on there, 10 btdc, 5 btdc, and tdc.. but the only way I can get it to run properly is at about 30 btdc? is this right? I'm a bit confused :\

  3. that's alright I know more or less what I'm up to, just waiting on a condenser and a rotor cap that fit now.

    Atm I'm trying to source a cheap dizzy, the one in my motor atm is a sohc one with the single points set up, it's in pretty average nick, there is a little bit of side to side play and the oil slinger has half disintergrated, I've got an ok price for a uno eltronic setup, I'm not sure if the dizzy will fit my old school twin cam however.. anyone know?

    I will try the sohc one out with some new parts however and see how it goes :)

  4. well after further inspection it turns out I am indeed a muppet. lol, the dizzy is driven from the crank, and turns once for every 2 revolutions of the crank, so after turning the crank another 360 degrees.. problem solved, ignition timing is spot on.

    what's next you say? well I have checked the valve timing and that is all tickety boo, so I will replace and gap the points, replace the condensor, also have new leads, plugs, cap and rotor, which will hopefully cure the chronic misfire I have, if that doesn't work I will try a new coil, if I'm still not having any luck I guess I will try swapping a different carb on.. if I'm still not having any luck I guess I will whip the head off!

    bearing in mind this is somewhat of a learning curve, as I'm doing all the work by myself and am by no means a mechanic, does this sounds like a good plan? techo gurus? k thx :)

  5. I checked my timing tonight as I am trying to cure a pesky misfire, and as far as I can tell it is a full 180 degrees out ! :o

    Thing is the motor seemed to be running alright when I first put it in the car (fiat 1800 twincam) but it's hard to say since it was just at idle in my garage, it's developed the miss (quite a bad one !) since I have been road testing it etc.

    why would my timing go that far out? or am I just being a noob ? :o
