tl;dr-- Pretty sure the block's spark-plug-slot is damaged/untrue, cannot even drill-in the new spark plug I got when trying to revive this 193t this afternoon....I'm OK with the insertion of a spark plug in a manner where "it'll never come-out again", which is why I was OK trying to drill it in, but still no luck (may try again, after cleaning-up the new spark-plug's threads since they got a lil mashed the 1st attempts) But if I cannot get it to take this spark-plug, what are my options? I really like the 193, used to own a 194 actually, want this saw would pay maybe $100 for re-threading of that slot but no idea where to even go for something like that..
Thanks a ton for any help getting this "Echo-guy" to have a 193t among his climbsaws ;D

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I'm given broken 2-strokes often enough since I'm usually able to fix them if it's not some catastrophic failure (even then, maybe ;D ), anyway I cannot get any info on what happened to this 193t since its donor was not the one who'd thrown it out originally, however it looks pretty much like it was hit by a car that "realized & backed-off" once they hit it, I say this because the 2 damaged areas are "connected" and couldn't have both have been done by a drop (from any height), would've required "squishing" the unit:
- left-handlebar's AV mounting is sharply bent, and:
- air-box's cover was off, which is trivial, however when I came home w/ new spark-plug for it (was none in it when I received it), I couldn't get it to screw-in, and realized the threading in the block's spark-plug slot was off
[Different angles, hoping the un-true-ness of it shows, kinda hard to see but it's not really 1 section the whole thing seems slightly warped am surprised old plug was able to be removed:
(right at the top, the first spot where threading starts, is clearly 'un-true' but sadly seems the entire slot is un-true :/ )
I did put my drill on the plug, thinking maybe I'd "force it", still thinking there's a chance I could get that to work but remembered that "re-threading" exists so I just paused everything to come consult w/ you guys! The new spark plug's threading is already rough from me trying to drill it into place (since hand-pressure isn't enough at all), will clean that up before any next-attempts but honestly if there's a way for someone to just "re-thread" the hole for me it'd clearly be worlds better!! I know that's specialist-help, but I like the 19*T series (used to have a 194t actually) so would happily pay up to say $100 for re-tapping of that hole (or maybe I just source the engine block "half" that has it??)
Thanks a TON for any help on this one, I don't need help w/ the airbox itself in fact I always mod them anyways so was kinda looking-forward to making a custom fiberglass 'airbox cover' and installing my own filtration, but can't/won't bother with anything til I know I've seated a plug & gotten it to turn-over (compression feels very high, fuel in it was not stale, have no worries on unit's condition besides the obvious!)
(PS- I should note I am OK with "Installing it permanently", for instance when I was using the drill to try and "force it" into the bad threading, I figured that if that worked I probably wouldn't be able to swap plugs again in the future, that is OK I am fine with the plug being "permanently stuck" if it lets me get this guy running!!)
spark plug's threading, and packaging (I mean, the Stihl computer at Ace Hardware told me it was the right plug, have no reason to doubt
)
AAaaaand the bastardized unit itself, I'm pointing at the bad-spot on the handlebar on the left, the metal AV connect is badly bent but still stable (and I'd reinforce it before use anyways, weak/questionable handlebars scare the F outta me!), I'd initially have thought a bad fall could do this since I've heard Stihl's don't take falls like Echo's do, but this thing was squished between the handlebar and the air-box, so badly that the pressure went "past" the airbox and onto the plug's head itself, mangling my plug-hole!
(what a cute lil machine, lol, unsure why I love the look of Stihl gear so much
)
