I got a 2012 Ariens Sno-Tek 24" 920402 in that my neighbor owned, it has a 136cc LCT Stormforce engine on it and the intake valve spring retaining clip on it fractured right in half. That is what put an end to this blower after only 5 years. It also took out the valve stem oil seal with it when it broke.
I checked the parts diagram for this engine for those parts and they are not listed. It appears the only way your getting these parts from LCT is if you buy an entire new head for about $88!
Does anyone know an individual part number for these two parts or some place I can source them without buying the entire head, because I'm not buying a head. I looked all over the internet and on ebay I found one listed for the 163, 208cc MTD engine and it looks like its the same or close for about $4 but its a gamble. The little seal, I have yet to find. Is their a way I can match it up by size or the numbers stamped on the seal. I tried typing those numbers into Google, nothing. Anyone know what size seal it takes?
Or does anyone who works on these often have these parts spare laying around, new or used they can sell and ship to me?
Also be weary of these engine's. After working on one, I can say the quality of them is pretty low overall. If you have a blower with an actual Tecumseh, keep it as long as you can!
Here are photo's of the carnage.
Update, I found this one on ebay which appears will work, I also looked up the Honda GX120 AND 160 and it is this same retainer. Will this work in place of the old broken one?

and will this seal work in place of the old damaged one it measures 10mm outer dia and 6mm inner and that is what mine appears to be using a manual caliper as close as I can measure it.

I had the same thing happen to my Generac 3500XL generator intake valve. I borrowed the retainer and seal from my Honda HS80 snowblower's GX240 until the new retainers & seals arrived, so swapping the parts as you outlined will likely work. A short time later, however, the valve stem itself broke at the retainer notch and also had to be replaced, so examine yours carefully...

that's the downside of a LCT or a powermore dusty. most parts are UNIT parts, if they don't give a breakdown ,they list NA use this, always turns out to be the unit.
sadly if that motor broke a valve keeper it most likely also bent the valve stem when the valve dropped so going unit will save you time
sorry man,but thats todays oem thinking,

I'm glad to hear that, because thats what I did, ordered them separate on ebay for $10 total.

You can also get an entire kit with new valves, the springs and retainers for the Honda GX160 and GX200 as well as clones, which will likely work on the LCT as well, since it is a clone for $7.90.
Only downside, it could take ahwile to get here from China. Thats why I ordered the parts individually inside the USA for $10, because I would like to sell this blower this year. But anyway, those are the wsys I found around having to buy an entire head from LCT, which is retarded. They should outleast consider selling a kit like this for their engines, instead of leaving all of those newer Ariens blower customers hanging, if one of these parts goes on their engine. It's a shame they flaunt the Tecumseh power product name now.

LCT customer service just got back to me. They have great customer support and are very helpful.
They just got back to me and are sending me a kit for my engine. It includes valves, retainers and springs. They said the valves are not for my engine but the springs and retainers are. Their sending it free of charge. Most likely because it wasnt available.
I wish I didnt order the parts on ebay for $10 but now I'll have spares.
Also I believe the cause of the damage was my neighbor over revved the engine. He had the idle screw on top all the way screwed in so the engine was going full speed the whole time. Likely did that because their is no throttle. You don't do that! The overall quality of these engines is no where near as good as Tecumsehs were, but if you use it properly and take care of it, it should still serve you well for a good period of time.
Moral of story, don't over rev your engine and if you need those parts, contact LCT, they will take care of you.
I have a feeling after this, they will make a kit available for purchase.

I'm sure someone has. No engine is bulletproof.

Good point, lets see where these new wave of engines are in 30 years. Outleast with the old Tecumsehs you knew you had a real good chance of getting a few decades out of it.
