The red wire at the ign switch plug is the 12 volt feed not the white wire. Put a test light at back side of wire harness and turn key to is if switch is sending voltage out to starter solenoid. If power is coming out of switch test at starter solenoid the same way. If good there make sure...

Simple test. Without motor running Push throttle to fast position, then with your best finger pull back the governor arm, if arm has tension on it and pushes back that good. Now put throttle at low speed and again use your best finger and push on governor arm again, there should not be any or...

Nice to read that you are up and running again.

To figure out if you have a fuel pump problem just test pump as I posted earlier. Easy to do. This will conferm good or bad. Works every time, vacuum gauge can be a repair shops best friend.

7 years is way past the life off the carb pump gasket. Sounds like engine is flooding out because carb gaskets are hard. This condition will flood engine in just a couple pulls. 1st thing to do is a compression test 98-130 psi is good. Next remove muffler a look at piston for scratches or bad...

Ok now. You have a bad switch somewhere. Seat switch is 2 wires, jump across harness, try to start. if no start jump Brake switch same thing. If no start do same thing to reverse switch. If deck has mulch plug check switch. So if it starts being jumped replace that switch. Not the best way to...

Make sure the tensioner pivot is not rusted and pulling all the way off. If not the brake pads will never touch spindle pullies. If brakes are not hitting pullies that is something to check. Also make sure cable is in the grove by flat idler pulley.

Sounds like float is getting stuck someplace with float bowl, causing needle not to work correctly. Maybe you should just get new carb?

Only purchase the tank from a 4/5 star rating seller. I've had same problem. Cheaper is just cheap. Good rating good product.

Nice to read that your running again.

ok, use a vac/fuel pressure gauge at fuel pump and test positive and negative readings. Pulse line should show 1 1/2 lbs. or more, suck side of pump should read - 1 1/2 lbs, and out side of pump to carb is 1 1/2 lbs. If all good and hoses are on right ports it will pump. If all hoses are correct...

Did you replace fuel pump yet? If so what was the outcome?

.004 is correct. Both valves. At top dead center on compression stroke. Beware that intake valve is the lower valve. Sounds like valves not adjusted correctly, battery low or compression release broken.

Thanks, To hot? Remember that our military folks are wearing a lot of heavy stuff in temps much hotter. That's hot. Just sayin. Please let me know outcome.

Did the fuel pump help?

Did my reply happen, having trouble sending info.

Put vac gauge on suck port, should have -1.5 reading red side, put gauge on push port going to carb should have +1.5 reading green side. Test shows good pump is good. Ck for pulse any movement good. Ck for clog from tank to pump, ck power to carb solenoid and ground.

Ok, from what you say the carb needs to removed and cleaned the correct way, with a ultrasonic cleaner, I use it every time with lean running carbs. Fixes 95% of the time with new intake gaskets. Or just replace carb with new carb. Some times cleaner can't fix it. Really never had any problems...

If these test show positive you have a defective fuel solenoid or fuel clog from fuel supply ( the fuel tank) to the fuel pump.

You can test the fuel pump. The suck side should have 1- 1/2 neg vacuum. Out side to carb should have 1-1/2 psi. You can check these with old time vacuum gauge. Green reading is push side to carb and red reading is suck side to gas supply. To test for pulse just put vac gauge at pulse outlet, if...

Make and model of mower?

I need make and model of your mower. A pic would also be nice. Maybe I can help you.

Thanks for a reply Freddie21. You are correct with angles of idlers. They have about a 1/4" lip that keeps belt on if brackets do bend some, normal after some time. Just like helping mower people. 32 years at outdoor power shop I've come across things most techs over look. I have comebacks like...

Also you can slowly pull pto handle back almost all the way but not complety and belt should not come off as a test the worn out brake pads, lets us know the outcome.

Might sound crazy but you need to replace the spindle brake shoes. Look at the brake shoes or pads that push against the right side spindle pulley and you will see deep groves in it. What happens is the deck belt gets pinched turning in oppiset dirrections and the belt will always come off. The...

Kill switch is not being pulled far enough so no spark. Adjust brake handle cable tighter, cable will slide after time and will need adjustment.

Is this a walk behind type mower with handle you pull to release the flywheel brake? If it is make sure the cable is not sliding upwards where the 7/16 nut is by pull handle. if it slide up the kill switch at the motor will not open and you will not have spark. Cable end should be about 1/2 to 1...

The Kohler motor has a vent tube that goes under the plastic air filter housing and will dry and crack then fall off and suck anything in. Maybe check there.

From what I read you have a intake valve seat loose in the head, a bent or warped intake valve, or guide sliding out of the head.

Did you do a compression test? Popping at high rpm is because intake valve is not seating properly, or valve seat and guide are not where they should be. Even with good compression you will still get popping.

Poor pto switch or connection at the pto switch will turn off engine, so will a poor contact at the 20 amp fuse that feeds the mower from the battery. Try checking these for possible problems.

Brake on will crank.

Very possible that the spark plug that is white in color has a intake seal or gasket starting to fail. Try spraying something like 2+2 carefully around the intake manifold at cylinder head, If engine rpm changes replace gaskets or seals. Just something to consider.

ebay. Item # 12688798

20 amp.

Great that you got it to move, never seen a new motor locked up, maybe 1st owner tried to start it without putting oil in motor because motor does not come with oil in it from factory but will be in box.

Using the wrong size torque socket and maybe have damaged them. Pretty sure they are somewhere like a T20, T25, T27, T30, T35, Tap on socket lightly with hammer, maybe dirt packed in the top of screws, blow dirt out.

Ebay item#126887985944, $24.99 obo, seller is 99.9%, wsmowerparts. Just what your looking for.

I think the screws are 15-25 torque type heads. Should remove them.

Correct, also check intake seals or gaskets, plastic intake manifolds also can crack or warp. Some 2 barrel carbs have adjusting screws under the small brass or aluminum plugs closest to the intake manifold, they can be removed and adjusted after removing and cleaning the carb. I use a ultra...

nice

Check wires at points and condenser to make sure they are not grounding out when cover is put back on after adjusting point gap at full open position at the point plunger. 15-17 thousand should be a good gap. Make sure wires are at correct spot at plastic bushing on point assy.

Does it have a light at the handle controls? If yes maybe flywheel rotor magnets came off flywheel, If flywheel is loose engine won't run good and would damage flywheel key and would jerk pull rope from your hand. If you do look at flywheel check to see is weight is still on it. If engine runs...

Test fuel pump with vac gauge/fuel pressure gauge, remove inlet fuel line and outlet fuel line from fuel pump, should have 1-11/2 psi coming out of pump and about the same going into pump but negative reading. If good check vav hose going to fuel pump is not cracked and tight. If these are good...

What engine is it? Make, hp?

Need engine model number to help you.
