You asked: Blower is off, but what is the kill wire? The kill wire is the black wire that is connected to the magneto. Sometimes the small black magneto kill wire is under the magneto (bottom next to engine) and the mag has to be unbolted to disconnect (unplug) at the mag. I sometimes just cut...

You say: Taking the engine apart will be my last step If it still won’t run. That is not a good idea. I just put a really good engine back together that the previous owner took apart because it would not start. I think he mainly just wanted to see what was inside. He had all the parts in a tub...

If you do find the fuse bad an it keeps on intermittently blowing the fuse you can find re-settable fuses on-line at a reasonable price that come in handy when trying to locate and correct a overload or short which is usually in the dash area by the steering column or look for a pinched wire...

Try using a electrical tester such as a 12v test light or electrical meter so as to check the voltage.

Check compression or leak down. I've seen the valve seats come loose and hold valve open on those engines, usually due to the cooling fins being clogged clogged with oil soaked grass clipping restricting the air flow around the head and overheating.

then when you get a flat the tube is done. I only tube tires that have multiple leaks from dry rotted rubber. Right: and if the HIS tires are losing air due to thorns/nails, the tubes will get pierced and just another aggravation and time $$'s wasted. He might consider airing his tires to the...

AND their are lots of inner tubes available today, especially the lawn tractor type that are NO GOOD even when new. (and have premium prices) Only brand names of inner tubes that seem to work ok for me is Carlisle and Firestone. (and they are not cheap) AND I do my own flat fixing and tube...

Install tubes

Is this a type? You typed "When you went to CHARGE things up it would not start" ??????????? What did you charge? Battery or ???? Next: If you are not seeing a slight dip on a rocker arm as the piston is almost at TDC as it's COMING UP ON THE COMPRESSION STROKE with the valves set at minimum...

If you squirt a primer of gas into the carb throat and the engine briefly tries to start and run is a hint that the carb solenoid plunger is not retracting. You can disable (defeat) the carb Anti Backfire solenoid if desired per bertsmobile1 hint.

Do a leak down test or try checking the compression and let us know what you see???? Fumes and smoke out of exhaust is a hint. You can do a leak down just injecting about 20-30 psi air into the spark plug hole using a rubber tipped air gun with the engine locked at TDC. Listen for air out the...

Do this but be careful and have the rig outside. Disable the ignition so as to not get a spark. (gas may spew out the spark plug hole is why the ignition is being disabled) Check the condition of the oil for gas contamination and also if the oil level is indicating high it may have gas in the...

Watch both valves. I seen where Honda and Predator engines also have the compression release on the exhaust valve. Watch for the dip on the exhaust valve. Appears you have a carb problem also or the carb springs in wrong. If you can get it running smooth using the electric start just go with it...

Honda and Honda clone engines such as the Predator engines might have the compression release on the cam shaft exhaust valve. (instead of on the intake valve) It's quite common for the ACR to fail which will usually require replacing the camshaft. On some engine such as the Briggs Intek single...

edited typo above

Yes. I've found them Nikki's to have a slight learning curve. I've got to where i do not dread them quite as much. Just a little measley, wimpy, weak looking little o ring or a seized screw will upset the apple cart. AND keep your fingers crossed when subbing the cheaper Nikki clones. I seem to...

Just a hint: To do a quick test to see if reducing the valve lash will do any good so as to get a compression relief I first measure the valve lash, for example if I know the ACR is on the intake valve on a single cylinder OHV engine I FIRST MEASURE THE VALVE lash with a feeler gauge and if the...

Here is some info you might re- search. You posted your Tecumseh engine is a 206820B I see the OEM 730326 is NLA BUT universal replacement 435351 is available and replaces 37425, 36914, 730326 In post #54 you posted this number as stamped on your starter. I've had good luck with db electric...

Back to your post #11. (last time we heard from you) You previously said the seat switch is disconnected. Have you ever operated this mower with the seat switch disconnected? The reason I ask is because if a seat switch is disconnected, unplugged or bad when the electric PTO is en-gauged the...

Does your owners manual show a Tecumseh part number for the starter? Does your starter have a Tecumseh part number on the casting or otherwise? (tecumseh sometimes has a part number stamped on their starter. See if the number on the starter matches the part number on your owners manual parts...

Look at post #31 Before you attempt to take the starter apart to check the brushes and commutator/segments and make sure the pole magnets are still secured watch some you tube videos about such. I've seen a magnet come unglued and stick to the commutator. (starter would spin/drag but still go...

Ignor my post #41. Read post 42 and 43. I misunderstood your post about the low voltage at the SOLENOID in your post 40. I was thinking you were referencing a clutch solenoid instead of STARTER solenoid. Does your starter solenoid look like this one with TWO small spade terminals or does...

Do as bertsmobile indicates in pst #39. (so as to locate where the voltage is being reduced) BUT!!!!!!!!!!!!! Good to hear you knuckled down and started using a vom for testing instead of just guessing. Voltage is kinda hard to see with naked eyes, best to use a electrical tester. I cannot find...

Appears you have lost some ground. (it would at least run before you did the new gaskets, but was hard to rope pull) I noticed you said it was one cog off in a previous post but would run ok, just hard to rope pull. Usually a engine will not start or run one cog off if you are talking about...

AND another maybe by Einstein I have to keep a heads up for this one when working on stuff, especially carbs. Insanity: Doing the Same Thing Over and Over Again and Expecting Different Results

Here is some info about working on them dual throat Nikki's that you might reference if your ebay dual throat carb stuff don't pan out. If not already done install a Briggs red fuel filter and a fuel petcock. Just another hint: I taken parts out of new clone Nikki carb's that did not operate...

If the engine starts spinning normally install the valve cover see if it will crank, start and run.

You might watch some you tube videos of how to set the valve lash on a Briggs 33 series engine. Here is a link to one video: I suggest you watch more than one video. Also note that you are turning the flywheel CW when going past TD on the compression stroke.. Set the intake valve lash at a...

What is the Model number and serial number of your 1998 MTD tractor? We need this info so as to try to give you logical answers to your questions. The neutral safety switch is usually close to the clutch/brake rod linkage and is sometimes not easily seen in behind the engine and the plunger...

Did you adjust the intake valve per the Service manual at 1/4 inch past TDC of the piston? If you did this and your set the intake valve at .0025 at 1/4 inch past TDC of the piston and it still hangs insert a feel gauge under the rocker arm so as the clearance becomes .0005 to .001 and test...

What is the model, type and code of the engine?

from post #6 you wrote: So the clutch harness is bypassed and so seems to be the seat as well, cause I don’t have to be on it to start. Are you saying it will crank with the clutch not depressed? Have you ever seen this mower operate correctly or is it a new to you mower? Reason I ask is if...

What is the model, type and code of the engine on your Poulan Pro?????

Just wondering why? Do you have the stator out of the engine or is the stator in question still installed? Is your charging system not working, are you replacing a stator or are you installing a charging system onto a Briggs engine? What is your engine Model, type and code and what are you...

Poulan Pro???? I've got a chainsaw with that name but it does not use a briggs engine unless Wilbur installed a replacement engine. What is the model, type and code of the engine on your Poulan Pro?????

Final test: cables directly from car battery at 12.40V, Neg cable to engine grounded, Pos cable to starter post (still measuring 12.40V), I get a spark, but starter DOES NOT WANT TO TURN!. Sheeeeeesh! TAKE THE SPARK PLUG OUT AND SEE IF THE STARTER WILL CRANK THE ENGINE OVER. You need to keep a...

Might try unplugging the electric clutch and do a test.

Make sure the bendix teeth on the starter are en-gauging the flywheel teeth properly. (sometimes the starter bendix teeth won't en-gauge (mate) with the Flywheel teeth properly and the starter will lock) As a test take the starter cable wire loose from the solenoid (relay thingy as you called...

You might check try. https://www.dbelectrical.com/

Couple hints: My impact usually will break them loose, BUT I have a big anvil and a big vise right outside the shop and every once in awhile I get one like that (really seized) and need to remove/replace the blade. I take the deck off to where I can get to the top pulley nut and remove the...

Thanks for the comeback. I need to start paying more attention to the engine code when looking at IPL's for Briggs engines.

Briggs twin cylinder OHV. You said in a previous post that no gasket was used just sealant. You can go to this link and see a gasket set for your engine and the sump gasket #12. You say you bought it NEW. Appears Wilbur may have been into the engine and did not use a gasket. I do not know about...

You probably need to start a new thread about your Poulan. this one is 7 years old. Take the spark plug wire off and crank. If it turns over ok with no spark to the plug it's slightly out of time. (timing too fast) This can be caused by the magneto and if it's electronic ign replace the magneto...

Post up the COMPLETE model, type and code of your engine. What caused the sump on your engine to crack? (most likely it did not come from the factory cracked)

HMMMMMMM Dual throat Nikki carb. I've seen the o-rings inside those Nikki carbs cause that engine speed changes. I did not say that carb is your engines issue but it's a good suspect. Here is a link to review about your 796997 Nikki carb. (repairs, etc) https://outdoorpowerinfo.com/repairs/...

Did I overlook where you posted this info? What is the model, type and code of your engine????????

Not worth the effort trying to remove or even drill through the steel self tappers in the aluminum housing. How do I know this. You should also check this first before attempting to rebuild or re-work any spindle housing, I've seen some of them old spindle housing not hold a new bearing race...

What is the model, type and code of your engine???????? As star tech mentions in post 5 the governor idle adjustments have to be correct. If you make these adjustments with a bad carb it just makes things worse. AND I've seen Nikki carbs have those symptoms and most generally it is the Clone...

as hiw49 says the 398811 for less than $20 is suppose to work on that engine if it only uses ONE external flywheel magnet going past the coil. Some old Briggs engines had two magnets outside the flywheel spaced apart by about 1 inch going past the coil and the magnetron breakerless coil would...

When the end play of the crank is excessive using the thin sump gasket which is usually .015 Briggs mentioned in some of their old service manuals to use a shim kit and shim the flywheel end of the crankshaft. This is one of the reasons I measure the crank end play BEFORE removing the sump...
