hi to all

i'm building a tricky ty 175.

i rode it yesterday, and the engine doesn't revs freely as it should be.

y have an electronic ignition "ty trials" 'bouhgt at bultaco uk and a mikuni 24 mm flatslide.

could somebody give me a basic jetting for this carb.

the engines runs quite well, except at high revs like if it was too rich,the main jet is 130 or 140...

or maybe an ignition issue?

cheers

nicolas

A 140 main jet is the one I run. Try advancing the timing about three degree

hi many thanks

mine is 140 and looks too rich for my 175...

i bought the ignition at bultaco.uk looks the same as ty trials one...is it?

cheers
