I've been reading this forum for a little while and just signed up to be a member. I'd like to share some pictures of a tiller I got for free from a neighbor who was tired of it taking up room in his shed. I'd also like to ask for some help with a couple issues I have with it.
Troy-Bilt Horse III with a Tecumseh HMXL70-132501 motor on it.
I've had the tiller for about a week and a half now and have put a bunch of hours into it dismantling, removing rust, and repainting it. I must say Evaporust is a lifesaver. It's a little time consuming waiting for each part to finish soaking but it's pretty much work free for me and can be happening while I'm doing something else.
The previous owner was the original owner who purchased it new from the dealer and used it up until about 3-5 years ago when he downsized to a Pony due to age and health. It has sat since then. He did drain the gas prior to storage which probably helped a lot. Overall I'd say it was in great condition for it's age and use and I really lucked out.
Thing I have done:
Replaced Tine axle seals
Replaced wheel axle seals
Disassembled and soaked the carb in carb cleaner
Rebuilt carb using new bowl gasket, needle, seat, screws (float was intact and empty)
Replaced all intake and exhaust gaskets
Replaced spark plug
Drained and replaced Trans oil (SAE 140wt GL4)
Drained and replaced motor oil (SAE30)
Added inline fuel filter and replaced fuel line
Replaced grounding kill wire
Replaced the air filter/ cleaner and oiled pre filter
Things I plan to do:
Add oil to PTO
Replace belt
Replace ignition coil
Finish reassembly optest and adjust carb/throttle/gov as needed
Issues that I am having and would like some advice on:
1) I failed to photograph the throttle linkage and how it gets connected to the speed control plate to the governor to the carb. I could really use a picture or two to clarify how things are connected. I have the TB Horse manual as well as the Tecumseh service manual and can't seem to find a picture or diagram that has the same set up as mine. I googled my heart out for hours yesterday and could only find the older HH60 motor.
2) I am not sure how the grounding kill switch connects to the speed control plate. It the end of the wire is male and the point on the plate (terminal) also appears to be male. Does this need to be soldered? That doesn't seem very secure.
3) should I be getting spark when rotating the flywheel by hand? I check the air gap between the flywheel magnets and Ignition coil and its in spec. The magnets are still magnetized but I don't have spark when rotating FW by hand or with recoil .
4) When all is put back properly and I get it running is there a video or procedure for tuning the carburetor? Right now I have the main mixture and idle mixture screw all the way in then backed out a turn.
I will take some pictures to share my project and help clarify what I'm talking about.
