44 IDF Synchronization

Former Member

I'm having a great deal of difficulty keeping my 44 IDF's sychronized. When I'm floating around 2500 rpm, I get a uneven running of the engine. I bought my Spyder turnkey and I've noticed that the bellcrank on the right carburetor has a long extension on it to allow the down linkage from the cross bar to be in the same position as the left carb. Is this common? It's my belief that this extension is flexing which would cause the butterflies on the carbs not to be in the same position and make the engine run rough.
Is there any mod I can make to the linkage to eliminate this extension?
Thanks for taking the time to look and hopefully respond.
