I swapped out my new su carbs from z therapy for the 73 flat tops.
A little confused on the heating hose which comes out of the engine and runs thru the carbs for warming.
1- Is there a sensor placed in this in this line? ( pic shows blue hose from engine to carb metal line).
2-Also , I see engines without the heat shield, do I need to replace?
3- the engine has been overheating in about 15 minutes and the mechanic can't find anything for cause.
Thanks,
Brian
