Back to square one (Now with videos)
Back to square one, giving it the beans misfire is back, video below is priceless
http://upload.youtube.com/my_videos_upload

if only for the vosa car driving past ironically.
Car is fine pootling or blasting round up to about 40, upto speed lmit then slow down misfiring stuttering the lot. have to pump the pedal to get any
movement at all.
Today i checked the carbs are balanced which they are (Impressesd with the gunsons carbtune)
Colortuned all 4 cylinders, all were slightly out, afterwards car idles much better.
Previously all new plugs leads dizzy coil lead, symptoms same as before
Cleaned all carb jets with carb cleaner, cleaned fuel filter.
Fixed air leak into fuel system.
Car starts idles runs lovely then as seen on video. Have had enough now, 70 miles of trouble free motoring since i've had it and that was half
the journey from picking it up. Any chance of dribving to a rolling road for fault finding out the window again.

Life moves pretty fast, if you don't stop and look around once in a while, you could miss it.

Dizzy
Dizzy, will give that a try. Thanks. When the video uploads you will hear the symptoms easily enough.

Where do you pick up vacuum? With twin 40s it's normal to use a non-vacuum dizzy due to the separate intakes for each choke, unlike a standard
manifold which feels the suck from all cylinders and so smooths it out.

possible fuel pump
Update, more issues today and appears to be no fuel flow out the carbs so think the fuel pump has died, and maybe has been iffy for some time. new
fuel pump tommorow, we will see if it is a fluke or actually the cause of my problems.

If you have an electronic distributor then it doesn't have a condenser. A common problem on Bosch distributors is the centrifugal bob weights
sieze and do not advance/retard the ignition timing as it should . Easy job to free off just a bit time consuming,
