Rough running 912 uls

Hello Rotax experts.
I have been building a Zenith 701 and as some of you have seen on this forum, I had a problem with one of the cyl. heads on my engine. I did replace the head and everything is according to specs, except when I try to do the carb sync, the engine is running rough, even though I am adjusting with a carbtune pro mechanical manometer. The propeller is a woodcomp three blade and has been adjusted with a 13 degree pitch for initial testing.
The exhaust springs I received with the exhaust system are not compressing the joints enough, so my question is, can this loose connection of the exhaust joints cause a rough running of the engine?
Thank you,
Johann G.
