Tecumseh HH-120 ignition

Anonymous-0 · May 29, 2008

I have a Sears Suburban 12 hp with the Tecumseh HH 120 engine. It has the solid state electronic ignition. It went bad several years ago and I was able to find a used one that worked about 15 years. But, now it went bad too and it seems impossible to find. I went to the Stens site and found an electronic ignition coil (part #460063) that says it replaces OEM tecumseh (part #30569A). Would that replace my old pulse transformer? Thanks for any help. Bob

I don't recognize that part #, but I don't think it fits an HH120. I believe the best thing is to go to www.overnight-solutions.com and get a 12V retrofit kit. You might also look at www.home.earthlink.net//~edstoller and get some ideas on a work-around.

Thanks everybody. Joe the coil on the site looks different than mine. The one on ebay looks the same as on the site. I was surprised the bids were up to $66 for used coil, wow. I think I paid $25 for a used one but I think it was about 15 yrs. ago though. I don't have another 12 hp engine to take parts off for a swap to the tecumseh. I saw the site for overnight solutions, but was skeptical. Do you know of anyone who bought a retro kit from this company?
Thanks for your help, Bob

OK, it does fit the HH120, but a newer model. It is discussed in home.earthlink.net//~edstoller

Got a spec and serial number? I might have an old dead engine with a good ignition in storage. I'm willing to look.

I just wandered across this old thread and thought I'd throw in my $.02 just in case you're still considering your options, I had the same problem with an HH120 in a Bolens 1257, those units are getting rare+expensive and it's a complete crapshoot whether even an NOS unit is going to be any good

I built a crank-trigger ignition that's working *great*, and I did it for less than $50

The ~edstoller site has good info, combined with the info on the site I'm attaching it was pretty straightforward to combine a Chevy crank-sensor+a GM HEI module+a Ford Duraspark coil for a cheap, repairable, and durable ignition

I have the same ignition system on an HH100. I had the same problem and wondered what to do. After some research on google, I found a great place to obtain parts for these engines. It's called Farmer's Exchange, located in Kennewick, Washington. Try their website: www.farmex.now.tc

Hopefully they can help you out, if you haven't already got it running!
