Hi all.

I have recently reco'ed the head on my f10a and now have it running great except there is a massive flat spot in the revs and if you pinch the gas down low it drowns. So I am leaning towards the carby delivering to much fuel? I have had a look around on the net to find the air/fuel ratio screw but can't seem to find it at all.
Can anyone help me?

Cheers Nick

Flat spots 90% of the time are too lean, too rich usually still works ok

there is only idle mixture adjustment, if it bogs when you open the throttle, look that the accel pump in the carby is working

I'm alittle lost are you talking about on the bottom of the carby where the linkages join to? If so how would I check this? Sorry for my ignorance but I have never dealt with a carby before!
