    2000 Kohler 15.5hp valve gap adjustments

    You are welcome. I edited the above post to be even clearer on that point. 🙂

    2000 Kohler 15.5hp valve gap adjustments

    A note for the fellows helping an old guy. SLOMO, ILENGINE, and HLW49. Thank you for your posts and information. It is appreciated. Casual users are not always “smart” enough to understand or pay attention, but some feed back is appropriate. The 19hp 2014 B&S Craftsman engine noted in...

    2000 Kohler 15.5hp valve gap adjustments

    THANK YOU to hlw49 from whom I caught enough specific information to ask AI a better lifter question telling me essentially, confirming hlw49, there no need to fix what isn’t broken. I had learned how to adjust a mower with Briggs Craftsman valves. Just figured was Kohler the same idea. I...

    2000 Kohler 15.5hp valve gap adjustments

    Research seems to indicate these CV models used hydraulic lifters and are self adjusting. Having changed oil and filters regularly and leaving the valves alone for 26 years may be why they still work. On the issue of adjustment, maybe “If it ain’t broke, don’t fix it” applies here. Apparently...

    2000 Kohler 15.5hp valve gap adjustments

    2000 Sears Craftsman green mower. 15.5hp Kohler. Never reset valve adjustments. Question: Having done it with a 2013 B&S engine, realized should do it with old Kohler. What would the proper intake and exhaust valve gaps be? Laugh, I know, but it runs perfectly 27 years later. Just...

    B&S Craftsman 2013 Platinum 540cc 19hp Compression Relief Failure Work Around

    (1). Interested in a professional opinion, I consulted at length with an electrical component design engineer for a multi national company. His opinion was that the starter would attempt to draw the same amperage from either the OEM style Lawn & Garden 230CCA, OR, from the Marine Deep...

    B&S Craftsman 2013 Platinum 540cc 19hp Compression Relief Failure Work Around

    The actual problem with evaluating this issue, besides quick guru surface guesses, is that the normal current draw varies greatly. In a tuned valve adjusted GTG engine with a fully charged battery, the electric starter should draw in the area of 100-200 amps. If fuel, tuning, ignition, valve...

    B&S Craftsman 2013 Platinum 540cc 19hp Compression Relief Failure Work Around

    Logical and no argument. As a practical matter, if it’s not useable in a cost free manner such as this, it junk yard time. Been doing the same thing WITH the small battery in place. Figured taking the small one out reduced the available load to just the large battery. As an aside, the engine...

    B&S Craftsman 2013 Platinum 540cc 19hp Compression Relief Failure Work Around

    The original 2013 small battery was a Sears Die Hard Lawn & Garden which seems appropriate. The mower is sturdy. The engines are not. The plastic carry handle needs removed and terminals refastened. As neat as I could make it to avoid being accused of Bubba and hopefully of Farm Boy Quality.😻

    B&S Craftsman 2013 Platinum 540cc 19hp Compression Relief Failure Work Around

    I have had similar 1999-2013 B&S engines fail due to the compression relief system breaking. Endemic apparently in Briggs engines and they do not care. One was junked since the mower was all worn out. One was rebuilt at expense. The subject engine here has been used for two years after...

    Repeat of Compression Relief Failure Causing Choke-Sputter-Die, or Both?

    🎄HoHoHo! Three steps forward, two backward! After valves adjusted, using screen to turn engine impossible. The similar B&S engined mower junked last summer started most of the time using canned starting ether. And then it didn’t. My wife may be right. I wish she would quit teasing me.\/👁️\/

    Repeat of Compression Relief Failure Causing Choke-Sputter-Die, or Both?

    The engine now runs choke, fast, medium, slow, & idle properly. The compression relief system is definitely Kaput! It will not crank with the mower battery, but if a fishing trolling motor battery is jumper cabled to it, the engine cranks and starts. Things changed: -New fuel line, filter...

    No mud daubers nests or other debris in the muffler system visible.

    Repeat of Compression Relief Failure Causing Choke-Sputter-Die, or Both?

    That engine is attached to a SCAG Patriot. A long term solution, if needed. The Sears B&S here is a challenge. When adjusting the valves, I found the top dead center where both valves are loose slightly. Set the gaps and tightened them. Good so far. Resealed. I cannot say I looked for or...

    Repeat of Compression Relief Failure Causing Choke-Sputter-Die, or Both?

    My un mechanical wife went shopping and came home with a photo of the solution. All I had to do was go to the store she went to, match the picture to a new mower, and pay for it.🙀 I will look inside the muffler.

    Repeat of Compression Relief Failure Causing Choke-Sputter-Die, or Both?

    Yes. Both 0.004” feeler. Five gallon yellow cap top with breather air tube. Already drained tank and lines when I replaced the carb and fuel filter. Used new Marathon station 87 car gas.

    All large urban expensive. After I retired, I myself and me is who the mom’s at home in the neighborhood brought non starting lawn blowers and mowers, dull blades, or she could use some help because “I’m sorta too pregnant to push the mower.” For years, I have mowed two elderly, more elderly...

    I hear you about carbs. But the factory carb with no effort to clean, the factory carb with carb and choke cleaner, and the replacement carb all result in the exact same operation symptoms. If anything, it runs slightly longer with the replacement carb. The valves and compression release...

    Craftsman T2000 2013 B&S 540

    Followup info: The 2016 fixit bill was half of the original Sears store $14xx cost, +/-. The cam shaft and a valve were replaced in the process. As to the new carb, the engine runs perfectly for a while, will go smoothly screaming faster if governor is held by hand, returns to the governor...

    Info followup: ILENGINE: Thank you. As a simple old pushing 80 retired guy looking forward to my Ssecurity 2.8%? COLA, I am out of apparent real options that I understand how to do to salvage this one. What I “hate” is taking good care of a machine, it still looks very nice and clean, and...
