I disposed of my coil tower spring believing that all replacement Distributor Caps & Rotor kits came with replacement of the coil tower spring, as well. NOT SO!
1-AutoZone, Advance Auto Parts, & O'Reilly Auto Parts DO NOT sell a replacement spring for Honda Coil/Distributor.
2-Local Salvage yard couldn't help, neither.
3-Honda Dealers that I've called here will sell the WHOLE COIL unit to give you the spring, but not sell the spring separately.
4-Is there another place/shop/retailer to go, or another type of spring that could be used?
5-What problems should I prepare for by using a creatively engineered solution (pump spring from a liquid soap dispenser, cut to 1/8" above the end of the coil tower tip, same diameter as the coil tower)? So far, seems like I've got plenty of *umph* , and no CEL codes flashing. Possibly too much resistance, or not enough? RPMs at idle now at 900/1000, up from 750 (specification) that I had with a smaller, retractable pen spring.
Go ahead, laugh...It's working, though. I'm concerned about future issues over incorrect resistance to current thru the jury-rigged spring.
