Embick87 20 #1 Posted November 4, 2020 Ok guys i need help. I put the kohler CH 18S in the 18 automatic i have everything lined up and spaced perfectly. It ran great and the tractor works great other than a couple little things. While starting and stopping putting chains on and mounting snow blade it kept losing right side cylinder. I know it is the coil so i got both while i was at it. The left one is on just a little tight but the right one is right against the manifold the magnet wont clear let alone proper gap everyone i look up is telling me i need the ones i have. The origanls have 9449 engraved in them but that gets me nowhere Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,266 #2 Posted November 4, 2020 Notice there are two different coil heights for the Smart Spark system whatever that is. Have the service manual? Garry Share this post Link to post Share on other sites

Garry I finally found coils with dimensions. I have already looked at alot of the same manuals they all have an S on the front but all parts shown are Ch 18 Share this post Link to post Share on other sites

I will let you know how i make out again thank you. I just dont get why so many numbers for coils but gaskets and a lot of other things are interchangeable with these motors Share this post Link to post Share on other sites
