wheeliepower 141 #1 Posted May 5, 2021 (edited) hi, I have a wheel horse c-175 with a big problem. It has no spark. I parked the tractor 3/4 year ago, everything went well back then. Now i wanted to start the engine but there is no spark. I've already measured the ignition coil, it's ok. I also don't know if the carburetor works. the spark plugs don't get wet when I try to start. I already dismantled and cleaned the carburetor that could be an additional problem everything went great 3/4 year ago I don't know, does anyone have an idea? regards from germany Manfred I also saw this news about a similar problem Edited May 5, 2021 by wheeliepower Share this post Link to post Share on other sites
953 nut 55,229 #2 Posted May 5, 2021 The two most frequent causes of a loss of spark would be the PTO switch not being in the off position or corrosion on electrical connectors. To verify that you ignition system is functional you can take a small jumper wire from the battery "+" terminal and connect it to the ignition coil "+" terminal. With this done there should be spark at the plugs. 1 2 Share this post Link to post Share on other sites
pfrederi 17,739 #3 Posted May 5, 2021 Spray some carburetor cleaner into the carb then crank. If she fires you have a fuel problem. if no fire the you have to clean the points and make sure you have 12volts at the coil. 1 Share this post Link to post Share on other sites

wheeliepower 141 #5 Posted May 5, 2021 I don't found a translate for this part => PTO switch not being in the off position Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,045 #6 Posted May 5, 2021 Pto = power take off. Don't know your tractor model number so don't know which switch you have. Click on the picture in the link for more Garry 1 Share this post Link to post Share on other sites
pacer 3,169 #7 Posted May 5, 2021 Wait -- if you/he jumped from + battery to + on coil and still has no spark then its an ignition problem - coil, points, cond, etc. If this C175 has the KT17 twin, and I think it does, then its likely the coil - for some reason the KT17's like to eat coils.

wheeliepower 141 #8 Posted May 5, 2021 yes, it is a kohler kt-17 twin, model one no spark if I connect the + battery withe the + from the coil with a cable directly I have a check stick with a lamp, which I also have connected too between one spark plug and the spark cable, but there is no light too surprising, when I used it 3/4 year ago, everything was still working. now I wanted to mow a meadow, nothing works anymore Unfortunately in Germany wheel horse are very rare and I can't just try a part from a neighbor I have to see if I still have an ignition coil to test I have measured the resistances of the coil, they are OK (primary and secondary) <<< sorry for my bad english, only my friend GOOGLE help me to translate >>> 1 Share this post Link to post Share on other sites
pacer 3,169 #9 Posted May 5, 2021 (edited) Manfred, you are doing OK with the translating... The coil here in the states is readily available on the ebay with reasonable prices - $30-40. One of those sellers will probably offer overseas shipping, Check it out - Just put "Kohler KT17 Ignition coil kit " in search.

pfrederi 17,739 #11 Posted May 5, 2021 (edited) Have you cleaned your points?? Connect your test light to good ground and touch the other end to the small negative terminal on the coil. When you crank the engine the light should flash on and off. If it doesn't clean and reset the gap on your points....018" Edited May 5, 2021 by pfrederi 1 1 1 Share this post Link to post Share on other sites
wheeliepower 141 #12 Posted May 5, 2021 (edited) yes, I cleaned If I clip on the test lamp (as you wrote ) and try to start the engine, the light stays on forever (see pic) what do you mean with => "...........If it doesn't clean and reset the gap on your points" Edited May 5, 2021 by wheeliepower Share this post Link to post Share on other sites

What this means is that your points are never closing if the light stays lit all the time. Could be: Points still dirty Improper adjustment Broken wire or bad connection from points to coil You don't have to crank the starter for this test, just turn the key to " ON " and turn the flywheel by hand.

wheeliepower 141 #14 Posted May 5, 2021 so I turn off the spark plugs, then I is easier to turn the flywheel from hand I connected the lamp, I turn the key to "on" the lamp shines I turn the flywheel several turns but the lamp always shines 1 Share this post Link to post Share on other sites
pfrederi 17,739 #15 Posted May 5, 2021 Take the cover off the points. Make sure they open and close as you turn the engine over. Use a small file to clean them or some clean paper. Gap should be .018 inches. Share this post Link to post Share on other sites

You are correct however when i set the points with a timing light they usually seem to be a tad tighter than the .020 .. at least on some engines...could be worn plungers..

wheeliepower 141 #20 Posted May 5, 2021 (edited) Engine runs the arrow shows a point of contact where a piece of metal was pinched no idea where does that part come from no matter, wheelie is running now adjust the carburetor tomorrow, I also suspected and dismantled completely many thanks all the people here, who tried with me to solve the problem regards from germany manfred Edited May 5, 2021 by wheeliepower 2 Share this post Link to post Share on other sites
Tractorhead 9,064 #21 Posted May 5, 2021 (edited) Hallo Manfred, habe leider erst jetzt Nachricht bekommen zu Deinem Problem. Aber schön dass er wieder läuft.👍 Zuerst mal ein herzliches to von mir. Hast ja ein schickes Maschinchen. Die Jungs meinten, daß Du deine Unterbrecherkontakte mal reinigen und einstellen solltest. Btw. Bei längeren Standzeiten empfiehlt es sich, vorher den Vergaser leerlaufen zu lassen, damit er nicht zusetzt. Beim Sprit solltest Du ab und zu mal einen Blei ersatz Zusatz verwenden, denn unser Benzin hier in Deutschland ist immer mit mind.5% Ethanol versetzt. Das mögen diese alten Motoren nicht unbedingt gern. als weiteren Tipp Tausche die Spritleitungen aus, denn die originalen lösen sich durch das ethanol im Benzin langsam auf. Diese kleinen brösel schwemmt es Dir dann in den Vergaser und setzt den zu. grüsse aus Bayern Edit: (btw 0.020 meint 0,45-0,5 mm Unterbrecherabstand) solltest Du Hilfestellung zum einstellen benötigen, melde Dich einfach end edit: Edited May 5, 2021 by Tractorhead 1 Share this post Link to post Share on other sites
wheeliepower 141 #22 Posted May 5, 2021 (edited) hallo, ja ärgerlich das ganze top gelaufen, dann vor einem 3/4 jahr abgestellt und jetzt wollte ich ihn aktivieren und dann das...... bleizusatz mach ich bei jeder tankfüllung rein dachte erst mein problem ist der vergaser, deshalb hab ich den ganz zerlegt und gereinigt. jetzt muss ich mal schauen, wie ich das teil wieder anständig eingestellt bekomme hatte die schwimmernadel auch draussen und die verstellschraube von den umdrehungen ungefähr wie es war wieder eingestellt vielleicht muss ich mich nochmal bei dir melden, wegen einstellung. deutsch geht wesentlich besser, als das gehackte englisch obwohl ich bei mail nachrichten auch die "nur" kleinschreibweise und die satzkurzform gern verwende, wie du siehst grüße aus dem saarland manfred Edited May 5, 2021 by wheeliepower Share this post Link to post Share on other sites

I hope it is ok here to handle that conversation in German, it is easier for him than in English. Manfred asked how to setup the Carb to basic settings, because he disassembled the whole carb to clean even main nozzle was completely out. Is there a howto for the Basic Carb settings available 1 1 Share this post Link to post Share on other sites
