Tahoe, YW and thank you for the input and the link to your excellent thread on Tecumseh SSI ignition conversion options. Looks like a much more cost effective solution. I had considered some of those options in advance due to Ed Stoller's excellent website. I hadn't seen your conversion thread or I'd have probably gone with that.
I asked for the blue Bosch coil but Dale was out. He substituted an American made coil that is less expensive and supposedly identical including epoxy potting. It probably wasn't the best price but he seemed like a good guy so I figured 'salright.
After it was all said and done, I still had about $150 in my conversion so it's still in line with Ed's, Dale's, etc.
on the next one, I plan to use Ed's instructions, dig the epoxy from the back of a burnt up module and bypass the electronics and use it only as a trigger to fire a coil through a Chrysler control box. I think I can get it done under $50-60. Remember too, mine are the last generation modules, different from yours.
I did find a website that had generic blue coils for like $25, was going to try one, but I dunno. My Bosch is holding up well after 3 yrs of abuse.
Does your coil have any part number? I am wondering if it can be sourced through somewhere else beside Dale?
I had a light squeal from an idler same as yours, shot of lube/WD40 and she quits down for a bit. Someday I will replace it,...someday
