In seems I made a mistake. I just finished installing Bosio nozzles in Bruno, my 1982, 300D T. He seems to have much more power, but he's not nearly as quiet. In fact the engine sounds kinda harsh when accelerating... Almost as if the switchover valve has been by-passed, which it hasn't. Is this normal for Bosio nozzles?
Also, when I turn the key off, the engine wont shut down until I press on the accelerator.. I can't find any loose vacuum lines, and the power doors still work......
I'm seriously considering cleaning up the old nozzles, having them pop tested, and re-installing them.
Any suggestions? What's the best method for cleaning nozzles? Will soaking in brake cleaner work?
Thanks in advance.
