On the anti-fire solenoid, rather than just removing the rubber boot, cut the little shaft close to the body with side cutters. Once everything is running correctly, replace the solenoid if you wish. Not cheap.

I have received one of those carbs where the fuel seat was not pressed in far enough. I think these are either untested, or failed units they sell. Cost more for them to take the return than to just ship another. I have the same running issue, ( not electrical) on two Kohler single cylinder...

I have the exact problem with a Kohler SV590 19hp. The governor brackets were previously adjusted and I think I got them close. Almost idles with choke partically on, spits fuel out when throttle increased. More than one OEM carb and one China carb. Mine does have a mixture screw, but little...

I think he meant disconnect the kill wires from the coils.

I have done all but recutting the valves. I have good heads for the single Kohlers, but not a twin. May pass on this.

Can they go in without a press? I have seen how to peen them. Thanks again for your help

Thanks, how would I repair the guides? Matter of just pushing them back in?

Hi All, What would cause a Kohler 25hp engine to bend two push rods? I am considering buying a used mower with this issue. Don't know if in one cylinder or both.

I think Chris and Zue on on track.

I usually go midway between specs. .006 and .008

If your machine has a fuel pump, it will be a black round plastic device with 3 houses attached. It will be in the path from the carb to the tank. One house from the tank, one to the carb and the other to the engine. The are used when the tank is under the seat or somewhere else that puts is...

Disconnect the starter at the solenoid, then the battery from the solenoid, then the blue wire from the solenoid to see if the fuse blows. This this helps then either the solenoid or starter is bad. Check to see if there are wires running behind the starter. These will get smashed easily. If...

You guys did a fantastic job of side stepping his questions and airing your thoughts on politics. I will answer as best I can from a consumer's side as I do repairs, but not as a repair facility. The electrics offer a lot to the consumer. No gas, no oil, very quiet and light weight and...

Hey Bert, read the post...he got it to work. Bad PTO clutch.

I am running a couple 2017 batteries. Signs of it going bad is not holding a charge, not charging fully, or a slow engine crank. Then it's time to replace. Walmart's price on their EverStart batteries is $29. I'm running a 2018 in my mower right now. At that price, it won't break your piggy...

All the engines I have worked on were 3\8" npt

Put a battery's Neg connection rite to the engine block and touch the Pos directly to the starter. This eliminates the wiring within mower. If it turn fast then you have a bad ground or Pos connection somewhere.

Before jumping rite in and cleaning the carb, is there an electrical solenoid at the bottom of the carb? This is designed to cut off fuel when the key is turned off. When the key is turned on, there should be a slight click at the solenoid. As the engine is cranking, squirt carb cleaner or...

Lots of good tip and I apricate them all. I do most of them now and haven't run across the cub carbs as I stay away from 2 strokers. I was wondering what a good cleaning solution is and I'm close using Purple Power.

good advice, will check

Thanks ilengine, I have ordered the OEM kit

Hello all, I have a briggs twin 19hp 2006 vintage. It has the single carb with the 3 screw fuel pump attached to the carb. It does not function and I don't see a rebuild kit on ebay. I have a pump off a Kohler that is new. Is it possible to install it on the Briggs using its pulse line...

Your expanation is greatly appriciated. Videos, most times, don't explain in enough detail. This carb was nice as it had the adjustment. Replacements for the Nikki come pre-jetted and not adjustable. Where is the same 'no-load' jet on them so as I can increase the diameter, if necessary...

Thanks to all that provided suggestions. I got it licked by backing the idle mixture screw out 2.5 turns. This engine runs great now. But, I run into this constantly and will keep these all in mind. Especially, the governor adjustment. Wouldn't think a carb replacement would require it, but...

All springs in good shape. It was suggested I adjust the governor. I'll do that soon.

Don't think it's a carb problem as both carbs are identical and out of working machines. If I hold the throttle arm it runs great at any speed. Carbs have been completely cleaned. Thanks man

Appears only the carb was removed. The surging goes away if I either choke it 80% or hold the throttle arm preventing the governor from pulsing it. I will do a static adjustment this weekend. Thanks

Surges at any speed in Neutral and no load. New gasket on engine side, no air cleaner mounted (no effect when mounted) and sprayed around carb with cleaner to check for leaks. Has happened many of times with rebuilt (cleaned) or new Amazon carbs on different engines. Always set valve...

I just watched a video on this. I'll try it and let you know. Thanks

The only governor adjustment , that I am aware of, is the governor shaft to the arm outside the engine. How is the static adjustment done. This is the first of this I've heard in doing a carb replacement.

Even after cleaning with the USC, the carb surges. I was thinking it was due to not cleaning the jets under the plugs. Do you have this issue?

I have questions regarding the cleaning of carbs. I disassemble them then soak in a water\Purple Power solution using a ultrasonic cleaner. Then I blow it out with air, spray with cleaner, use small wires in passages, clean with cleaner and finally shoot with air. This works with carbs that...

Ok Gents, what's my problem (the engine's problem). Kohler SV590 19 hp single, new to me with carb off. I installed the carb and it ran great as I did other repairs on the mower for a month, or so. It started to surge, one day, so I replaced the carb gaskets, filter, fuel line to tank and...

If you have to remove the spindles for any reason, the mounting bolts snap off very easy. Use penetrating oils and rock the bolts back and forth with a box end wrench. I don't use the impact until they are loosened.

What weight oil are you running. 5w30 in that cold weather.

If you close the choke slightly and it runs better, then it's starving for fuel. Usually still dirt in the idle circuit of the carb. Cheap replacement carbs are 50\50%. Some work great and others will either leak or surge. I have found to cure the surging, increasing the size of the idle jet...

Another suggestion, switch to the ethanol free gas for the winter use. Fires much easier. It's more pricey, so reg gas for the summer would work.

Disconnect the mag wire, then jump a wire from the battery pos to the starter either at the starter or its connection on the solenoid. If it spins then, with the engine off, jump the battery pos to the small connection on the solenoid. May be a orange wire. If this works then there's a...

Confused? Take a small junmper wire and go from the battery pos and touch the small connection on the solenoid. Usually it is a yellow or orange wire. If there is another small connection, it should go to ground. If the solenoid turns the starter, then all that is good. If not, then either...

manualslib.com is good.

From my experience, when the hydro is failing, it will tend to slow its top speed as it warms up. Usually after 10-15 mins of moving at full speed. Lowering and changing the oils to 20w50 may buy some time, but not a fix.

No signs of leakage.

on the 2-4 magnets inside the trans

In the process of changing the oil. Looks black and thin. Waiting for oil delivery. What would be the symptom of a defective breather cap? It looks as if the larger outside top cap is missing. The smaller rubber plug is in the hole tight.

Agree

Nicely explained. Now I understand the heat issue and why to put in heavier oil. Thanks,
