Hi All, excellent thread,
I have mm5 5 port and has done about 5 litres now, tune is pretty good except (comes off at about 115)when I come off the track the idle stays up for a bit longer than I would like, maybe about 10 seconds before it drops down,Is the low speed to rich or lean, It is the new carb were you have to tune the low speed needle.hsn is .5 in and low about 1 turn in?
Any help would be great.
Thanks
