I did remove all 4 throttles on my -84 yesterday. Two of them had cracks near the end where the diaphragm is fitted.
One seems to be glued together but the other one seems to be held together by the fitting for the diaphragm. Is this a common problem? I have searched the forum but did not fina any threads about his. Is the cracks from the plastic getting old or what could have happened?
Anyhow; do any of you know where to by new throttles that are not oem? Or perhaps the oem part is affordable?
