Is there a conversion coil or one from another saw that could work on the 450?
The cheap bulb primers like the ones used on the plastic poulans, Wild Thing,Woodshark ,etc. will work with a bit of extra work to make a holder and adapt that to the existing cover, a hole would be required for it to mount in.. The diaphragms are just about as scarce as hen`s teeth anymore, I rebuilt dozens of the OEM primers until I ran low on stock, I bought my last ten units off a shop selling out on eBay like 5 years ago and have not seen one for sale since.Thanks for your suggestions pioneerguy.I removed the coil from a WICO assembly, did some minor changes to the laminate frame and mounting holes and i now have a good spark.Now if i could just find a solution to the fuel primer system i would be happy.
