i have a similar problem.


she will start fine, but if i quickly open the throttle the engine will die. Also, unless i have the choke on so that she is reving around 2k-2.5k the engine won't rev past 3.5k-4k.


tis a bugger.


I need to put new carb rubbers on the engine and the carbs could probably do with a good clean.

Have you just solved your own problem?
Any air leaks from carb rubbers will give the feeling of bogging down on hard acceleration.
I found this out when a mechanic managed to fold a rubber in half on reassembly!

not yet. I've gotta sort out ma blowing exhaust then sweet talk some lectuers so i can take her into the uni workshop and put the new ones one. Also from reading this post i've probably got some water in the tank.

There is an alternative way to sort water in the tank, buy a litre of 99% Isopropyl Alcohol and put in 300ml per full tank of petrol.
It binds with water and gets burnt off as fuel.
