I’ve just been out in the roadster and thought I’d do a bit of routine maintenance when I got home.
The car was running fine. I checked the plugs and found them a bit sooty .
I cleaned them and refitted them, gaps were fine... In my wisdom I decided I would adjust the mixture screws on the carb. I took them out and cleaned them off and reinstalled as we the manual.... I followed to text on how to adjust but I now have a popping in the exhaust... no matter how I adjust them it still pops.

The adjustment screws are easy to turn by finger pressure and in fact seem a tad loose in the treads.... I don’t know if this is normal or not.

Plugs are new NGK , new E-Fire distributor and new leads and coil a couple of months ago

As I said, it was running fine until I meddled with things. any ideas?
