A 1 1/2 mm gap would be a tad much methinks...
1 to 1 1/2 is what the manual says but I might be reading wrong

It's definitely what Patrick said. When you apply brakes, the carb is closing and killing the engine. You may not need to adjust the linkage, just turn the idle screw in a bit (be careful, I'm talking about the idle screw, NOT either of the tuning NEEDLES). When neutral, there should be a 1 to 1.5mm carb gap, when you apply brakes, this should not change. Good luck
and verified. +from past experience if it is under 1mm it wont idle right and on some engines wont even start without pulling the throttle when you let go it dies. my.002
