I believe tickover is another word for idle.
If you have rolled it, before you do anything, bleed the oil pump if you have oil injection.
Rolling often stirs up a load of crap in the tank and it gets into the carb, and blocks things up.
Take the carb off and give it a good clean, especially the pilot jet.
The violent shock of rolling can also cause the carb boot to crack, and make an air leak.
