I think the t5 carb has a be4 atomiser. I tried others when trying to jet a pipe but there wasn't a big difference between them to me. I'd be shocked if it's an atomiser pilot jet issue but worth experimenting. Does the choke make a difference or winding out the air screw alot and combining it with reducing the tickover speed to virtually nil? Both worked on mine when the crank seal had given up. Also if it runs fine with a bolt in the clutch cover instead of the breather it would point to a failed seal. Good luck with it.
