A65T Pre OIF Tuning Help Needed

[DODGE]

Hi all,
I recently gave my 1970 A65T a birthday (new float valve, carby clean and gaskets, new fuel lines, taps and filters) and now it runs terribly. It idles well but is hard to start, backfires and does not want to rev out in any gear. It ran fine before my intervention.
Anyway, as all settings (float height, idle air screw, needle valve height) were returned to what they were before the carby clean, can there be some other reason for the problem?
It seems to run rich so I was going to drop the needle a notch but thought I'd seek advice 1st.
Also, does anyone know of someone in Aberdeenshire who could help me tune it?

Are the gaskets to the head ok, some Amal flanges warp at the connection.

I don't know.
I did replace the gasket with the O-ring as shown in the parts book and as mentioned in the Amal gasket kit.
Do you think an air leak might cause the problem - too lean?

Those concentric carbs can block in the very fine pilot drillings, I would take it off and go through all the fine drillings with an aerosol of carb cleaner. Make sure the new float is ok on it's spindle. Blow through inlet to make sure the fuel is shutting off. Probably something small. Good luck.

Armed with a new flange gasket I set about to remove and clean the carb again. When removing the LHS side cover I noticed that the HT wire was loose in the coil. Once re-attached the bike fired up, idled and ran very well. It must have had sufficient connection to idle but not rev.
The bike now accelerates well of the bottom and revs out in all gears. A slight flat spot in the mid-range but nothing to really affect a ride. I got out on Saturday and Sunday whilst the weather is good up here.
Cheers
Andrew
