To set your jets to baseline, turn both fully in then:
Rough initial settings:
Low speed jet 1/2-3/4 turn out.
High speed jet 3/4 -1 turn out (1 & 1/4 max)
These will need to be adjusted depending on your setup.
The Tilltoson HL-334 does not like poor valve sealing on the inlet side. If you are experiencing rough idling do a leakdown test on your inlet valves to confirm this is not effecting your carburettor.
