KT-735-3076 Running Rich/Poorly Under Load

Greetings, I have a KT-735-3076 engine in a Troy-Bilt Super Bronco XP with 128 hours. When it stalled out after hitting something and wouldn't start, I made the mistake of jumping it with a running vehicle. I replaced the battery and starter. Fortunately, the voltage regulator was OK. However, it's ..

CV25S idles WOT

I bought this Bobcat ZT (older 2005) mower with a bad carb. Replaced the carb and it worked fine for a couple mows then started puking fuel and flooding the engine. Ordered another Nikki and installed it today. Now the engine fires right up but idles at or near WOT with the throttle against the idle..

CV-16s spark advance module

I have a Kohler Command CV-16s 43514 with the SAM module, my module recently went out and it would not advance the timing past idle. I bought the aftermarket market DSAI 12 584 12s unit off EBay for $20, the engine runs but pops going from idle to full throttle, to be expected for the price. I tried..

Kohler 7000 series weak turn over

I have a Toro mower with a Kohler 7000 series (KT735) engine. It doesn't have a lot of hours on it. Three seasons on my 2 acres. Last year at the beginning of the season it had a weak start. Would lift the starter but stop when it hit some compression. Couple of tries and it would go. This year its ..

Control Group springs

Does anyone have a picture of the Control Group for the KT735 Kohler engine? The springs came off when I removed the Control Group so I could get at the muffler bolts and I don't know where they go!..

KT745 ISSUE

I had to replace the head gaskets on my KT745 due to one blowing out. After putting everything back together it doesn't want to start on choke and when I did get it started it doesn't sound right, kind of muffled sounding and it sounds like it is sucking air around carburetor/air intake. Looking for..

Kohler CV23S One Cylinder Backfires

I own a Wright Sentar mower with a Kohler CV23S engine that has 840 run hours on it. Three weeks ago it was running fine, suddenly the engine RPM dropped, and it began to backfire, blowing black smoke out of the muffler. I installed a new gas filter and spark plugs. Both cylinders show a strong spar..

Add electric start to new Kohler CH440

I've got a recoil start engine on a stump grinder. I'd like to add an electric start motor to it but I don't need any of the charging parts. I'll simply connect a lithium 12v jump starter battery to the starter when I want to start the engine. I'm 79 years old and it's just too hard to pull start. D..
