bakt4kids on Ebay has standard sets...Not Kohler but Stens/rotary.  I have gotten kits from him for other engines.

When you do the rebuild please share as much information and detailed pictures as you can. There are not many Kohler twin builds documented on here. Brian Miller's site has quite a bit of good information on them and offers some Kohler and after market parts for them.

yea i actually live less than a mile from the big show. thanks ill take a look at the guy on eBay. this is my first time rebuilding a twin. my original engine was a series 1, and last summer it started getting the death rattles so i figured this winter i would build a series 2 for it. so i bought a junk engine that broke a rod and im just in the middle of tearing it down now. so far it looks good just getting the crank tuned down .10 under and i should be good to go. the main things that im buying other than a kit is a new gov, oil pump gear, oil pump, and dicky bird to run the points. i wish i had a way of posting pics of my build but i don't. sorry fellas

Welcome stubs, I'm new here myself!

 

Man... I'd be in a world of hurt if I didn't take pics / vids of an engine that I've never torn into before.  (ahhh...who am I kidding, I'm in a world of hurt even with pics & vids )

 

if it takes pictures and has a way to link to a PC (bluetooth, data cable, etc.), you can post them to free photo hosting site.  I used photobucket for years but they turned Martin Shkreli on us...  I've been using imgur for a few months and I'm very happy with it.

Kinda like this...red and black it might fit in with the ..., Good luck with your engine/project, Jeff.

i think that would take a little more work than id like to do stuffing a sbc in. haha nice build though

 

[stubs 5]

got another question here. is it possible to put m18 pistons and rods in a kt17? 

 

[19richie66 16,879]

KT 17 series 1 was splash lube and series 2 and M18 are pressure lubed. I am not sure if the rods would be drilled the same. If you look in the Kohler service manual, I believe the 17 and 18 were both the same bore and stroke. 3.12" bore and 2.75" stroke.

Here is some information from Brian Miller's site that should help.

New connecting rods for Kohler KT-series and Magnum engine models MV16, KT17, KT17 Series II, M18, MV18 with a wrist pin hole diameter of .625" and STD crank journal diameter of 1.3733"/1.3738". NOTE: Crank journal must be reground .010" undersize to match this rod. And new rods for model KT19 is no longer available. L Also, the KT17 cylinders are different than the M18 cylinders because the OEM KT17 rods are narrower than the M18 rods. To make the KT17 cylinders work with M18 rods, grind away (notch out) the lower portion of the cylinders until the rods clear. Or acquire a couple of M18 cylinders that's in good condition. (The OEM [US] manufacturers are phasing out many parts for flathead engines due to EPA smog emissions. But some parts may still be available in aftermarket.) The alternative to using undersize rods - If STD size or .010" undersize rods are in good condition, the matching crank journals can be reground so they're perfectly round again then if the original rod(s) isn't badly scored or burnt, it can be resized to fit to odd-size undersize journal(s) with .0025" oil clearance. NOTE - The maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shaped, which will allow it to less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and might eventually knock and possibly break. IMPORTANT: To prevent scoring of the rods when the engine is ran for the first time, apply clean motor oil, gear oil or lubricating grease on crank journal before installing rod.

Im building a series 2. Iv checked the numbers between the 17 and 18 and I thought they were different. Not sure if I remember correctly now or not? Supposably the crank journals are the same, but i can't find a spec of the width. So im not sure if they would work or not. The reason im asking is kt rods and pistons are very expensive and the m18 rods are reasonable. Im learning a lot as I go on this build. I had a series 1 engine that is in great working order except for a rod starting to get loose. So I bought a junk Series 2 and I'm taking my series 1 and turning it into a series 2.

NOTE: High-quality ring sets, pistons and piston/rings assemblies are also available for other makes and models of small gas engines. And the piston assemblies that's offered here will work with a stock connecting rod and crankshaft without the need for rebalancing. And always match a billet connecting rod of a certain length to an aftermarket piston (Arias, JE, etc.) that has the correct compression height. These two parts must be matched for the piston to come flush with the top of the engine block, or have a few thousands of an inch pop-out. If using a Kohler connecting rod, the compression height may not be correct with an aftermarket piston (Arias, JE, etc.) that has the wrong wrist pin offset. The same is true with a Kohler piston and a billet connecting rod of a the wrong length. You can find piston ring compressors on eBay
