My TeePee was Idling way to high... Dad adjusted the automatic choke and now it Idles fine but under load it chuggs / misfires pretty bad... (where as it didn't before).
I dunno much about cars but my guess is maybe the mixture aint quite right on the carby.

Can anyone give me any advise or maybe instructions on how to adjust the fuel air ratio on the carb maybee its running to leen or something.

I added 2 pics of the carb, if someone could edit them to show me which screws to adjust or something that would be great.

Any advice much appreciated.

what did ur dad do exaclty cos ur choke should be automatic, so im guessing he turned the fast idle screw when he though he was adjusting the automatic choke.
ive scanned the how to set idle for you. it's really straight forward. also these cabies arn't the best if never taken care of. the secondaries sometimes size(bs, get sticky) up so put some carby cleaner in there to help it alittle only 3 bucks a can. squirt some in there and run it till it evaporates.

don't touch the mixture screw cos it's sealed and not meant to be adjusted. the one u want is in the second pick it's the idle up screw
good luck
