Experts - help please. I’m new to Wheel Horse Tractor life!
So - I’ve pulled out an inherited tractor and have decided to resurrect her. Unfortunately, no spark :/
I’m looking for help on diagnosing no spark.
model - 417-8
engine - Kohler KT17
Done thus far: (aware that some have no implication on spark.)
- new ignition switch
- new battery
- new starter
- new ignition coil and wires w/ plugs
- new condenser
- new points
- new starter solenoid
- bypassed all switches except oil and seat.
notes:
idiot lights removed.
All fuses tested with Ohms as well as visual inspection ..
coil tested w/ ohms as well
all switches bypassed except:
-oil switch ( don’t think it has any implications other than a visual indication for idiot lights. )
-seat switch
ran a pos from batt direct to pos of coil - nothing; no spark.
Electric is as follows:
- Starter switch wired to solenoid
- - solenoid to starter
- - solenoid to batt
- one wire from starter switch goes to engine ( I think this is for batt charge / flywheel)
- I have two yellow wires, which are married up, that go to engine which have constant power; They power coil. Comes from switch and seat.
Help - what the heck am I missing ?

Ok, So I am seeing that most of you are leaning towards the ONAN engines being crap. That said, I have 2 416's # 1 is a -8 and # 2 is a -H. Both have the -216 in them. i was thinking of rebuilding the engine from the 416-H, but I am also considering changing the engine out with a different type. What are the recomendations? I am seeing Koler, what else will fit?
Thanks
Dave.

A HUGE thank you to Tony @Docwheelhorse for settin' me up here.
The generosity of some of our members never ceases to amaze me.
This here is another 1974 C160, but with the rare Tecumseh HH/OH160 OHV engine. Made one year only.
It's rough. Very much in need of a full disassembly and restoration.
When it came here it was missing one tie rod and the other was broken off one end.
Today I popped used tie rods on and Trina used her 867 to drag it from the drive to the shed.
The engine wouldn't move.
Tin was near chock full of skeletal mouseseses and their house.
Cleaned that out and the engine spins freely now.
So progress has been made.
It'll be a good long while before we get to this one but I just couldn't turn it down considering the rarity.

I'm looking for help in troubleshooting a starting problem with my 520. I used it yesterday to mow my yard for about 1.5 hours and when finished I let it cool down before shutting it off. It sat for about 2 hours and I put fuel in it and drove it on the ramps to clean the deck and after rolling it off the ramps I hit the starter and the engine made a noise and tried starting. I tried several times after that and no pop at all so I did a compression test and the front cylinder was fine and the rear was poor so I immediately thought of the valve seat being loose wedging the valve open. This morning I took the head off and much to my delight I did not see the seat as I thought but the head bolts were not very tight so I understand the poor compression (see pictures). The piston goes back and forth so that seems fine so I'm not sure where to focus my attention next. I am new to the 520 world and I tried searching the forums to find a thread that might walk me through this to no avail. I'm going to hold off putting the head back on just in case someone says to check something else related. This machine is new to me and has been smooth running, no smoke, good power, and always started easily with very little choke so I'm very surprised at this. Any help would be appreciated.
