been getting a few primer carbied brigg's last few months over fueling . on inspection i found the main jet with brass or stainless insert to be missing or fallen out caught in the mesh screen .

is our fuel that bad now its eating out the plastic bigshock ??

seems to be getting more common too , only once i have found the insert still there , and new jets are PHEW . almost cheaper for a new carb .
any thoughts in this one ?

cheers . Dave
