1969 tach question
 

have several tachs from original 69 camaros...3 of them have a needle that when flicked will go to redline and then return to zero , a few others when &quot;flicked&quot; to redline will return to 1000 and stop, next time will return to around 200 and stop. They can be manually returned to zero easily by hand. Is there a remedy for this or will installing them solve this issue.. meters seem fine except they seem to need a little lubrication?? down near 0. The rebuilders ive called of course,want to redo the entirre tach and dont give out free information [img]<<GRAEMLIN_URL>>/dunno.gif[/img] any help appreciated

Could they just be gummed up from sitting . Could you use some WD-40 and lightly lube the pivot aeria's?
