Hey guys, thought I'd share this monstrosity with the wider world. It's been handed down through the family since new, which was in... early '50s some time? Not sure of the actual date. The sticker is long gone from the deck but I still have the original - I think - engine, a 6B-HS in sad shape with a clunky conrod, but mostly complete (6B-HS 900160 1513060, from what little I've read you can't get real dates from that format - true?). It's old and dirty and rusty but the deck is solid as a brick you-know-what. The original grips are still intact, not even busted up on the ends. Anyway, the timeline goes that probably 30 years ago it was getting smoky and clunky, and was abandoned. Left outside in the dead pile for 10 years or so. Around then I had an awful MTD somethingorother with a dying drive system and generally falling apart all over, but a good engine. I stripped off all the usable parts and proceeded to retrofit everything onto the old dead Eclipse. Threw away all the flywheel brake BS. The Eclipse blade mounts with the big belleville washers and a single bolt so no funky adapters were required. I reused one of the MTD cables, adapted to the Eclipse throttle. The original wheels were too far gone from rust, they were peeling off layers like an onion, so I used the icky plastic no-bearing MTD wheels. The Quantum "5.5hp" is 5.5 no more (or maybe it's now a true 5.5hp). Ported, eyebrows rolled over into the bore down to just above where the top ring stops, shaved head, carb worked over a little with thinned throttle shaft, low profile stainless screw, smoothed venturi, main jet converted to use homemade #6-32 replaceable jets, plugged the bypass hole in the blade with lead shot and added an idle stop screw. All of which is totally pointless I know, since the governor never sees the need to give it more than about 1/4 throttle even when you toss the mower into a head-high mountain of kudzu. It's unkillable short of hitting a hidden tree stump. He has teeth! Logically, sometime through the years he acquired the name Chompers. The stop "switch" is sorta functional but in process of being replaced with the correct snap-in stop switch that fits the bracket. Also working on a canister style muffler being adapted to a 2 bolt flange to replace the ugly pancake muffler thing. And a different (wrong part number for this engine, but same format) carb with a real idle circuit (as if that's even necessary - but I want it, so there!). I'm kinda-sorta leaning towards buying real metal ball bearing wheels for it, and making new axles/spacers to get the front wheel offsets moved in closer to the deck where they should be. The scabbed-on MTD parts aren't a great fit there, I can do better (I have a lathe and enough raw stock to make something nice). Anyway, I'll add more when parts arrive and progress is made. Hope some of you enjoy this kind of thing.
