I don't think Webers are tempermental but do require work to set up correctly. You must be sure the linkage all works properly and in unison. You must spend time dialing them in with proper chokes, jets, settings. The only way to do that properly is by monitoring the exhaust gas and by performance of course. It is worth the effort. There is nothing like a set of well tuned Webers for performance.
