fuel/air mixture?

[darrsi]

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!
