Malossi reed valve kit

hi all

i have installed the mallosi reed valve kit to my 1987 t5 172 kit

i only matched the base plate to the reed block and smoothed the ports but im haveing trouble jetting the 30 mil carb.

i can run it on anything from a 124 main jet to a 136 but performance is poor.

it has a 60 idle jet.

it runs better with out the reed block in i feel i have missed something.

how far do u recommend advancing the timing.

it also struggles to idle even when the tick over is high.

please could you recommend a exhaust for this system as i think it may be the cause
