Happy New Year! I hope to have this part of the section ready to go before the spring season hits. So keep checking back. While this is down, hopefully I will have more time to get the rest of the site updated with new and updated information.

    I am changing the head gasket on a 1995 B&S Model#195707 8 Hp engine on my Snapper Mower.What is the correct torque for the head and exhaust bolts.I’ve seen 220 in/lbs. and 165in./lbs on the head bolts??

  19. Abhaya Gajamange says:

    dear sir, A friend shipped me a B&S lawn mower quantum XTE 55 model 128802 with 799868 carb. Was able to start mc but the throttle linkage does not function. Ie. the carb valve does not move with the movement of throttle. there is just a spring connecting the carb valve which tensions with the opening of throttle. I could not find a linkage with the carb valve and the throttle mechanism. pse advise with a dwg or photograph. this mc is in Sri Lanka and not many machines B&S available.

    thank you.


  20. Hi Everyone,
    I have a Tiller with a B&S 5hp Verticle Shaft Engine and I have rebuilt the Pulsa-Jet Carburetor, changed oil, new spark plug, adjusted valves to specs and installed new air filter. It started right up and ran with no problems. Idle was good and acceleration was smooth. Later on I came to try to start it and I could not pull the recoil. I thought it must be hydro-locked. I took out the spark plug and all this gas came pouring out. When I pulled the recoil more gas came out. I checked the oil and it was cloudy. I drained the oil and flushed the reservoir three times and put new oil (30W) in again. Dried the cylinder overnight and am ready to start it again, but not until I fine out what caused the engine to flood with gas. Any ideas?

    I have an ETQ7000 generator and that i left for couple years. When i cleaned it out, i removed the solenoid and sprayed it well with carb cleaner so as to release the finger. Once released and clean it freely moved in and out. My question is this – it seems that most discussion talk about the finger being in the EXTENDED position when powered off. Mine is in the retracted position when powered off. When powered it extends out which appears to extend the finger into the bolt hole it is attached to and stop fuel from going into the hole (just like the carb float needle) which allows fuel to go into the main tube into the carberator. Is this reverse operation another mode or has my solenoid failed and it is operating wrong? After testing and verifying this operation it stopped working altogether. I just want to attach it and leave it (in the retracted powered off position) if that is possible. Appreciate any explanations or thoughts… I just want to get my generator working again.

    what is the head torque specs for an kohler 27 horse sp engine we are rebuilding the engine and can not find a manual with the specs in it can you send me a free download site that you don’t need a credit card to get information

  24. Tony Briganti says:

    I have been using a Craftsman Edger (model #536-87010 of questionable manufacture) and just now read your section about “engines failure to start”.

    The engine ran for a while, but stopped and wouldn’t restart while hot. I’ve had trouble with carb adjustments to get it to run again. I have noticed also the Denso W20M-U spark plug had to be cleaned from carbon fouling, and reset the gap from .025 to .030 inches.

    Other than Craftsman, I do not know the engine manufacturer or the year or hp after reading the specs section for model numbers for Tecumseh and Briggs & Stratton engines. I am at a loss for complete identification besides asking for assistance before ordering any parts or gaskets etc. Could you assist me in finding out the manufacturer or the year or hp of this edger’s engine with only the model # 563-87010?
    Please resp to my email address if possible.

    I have a rally prizm push mower with a 4.5 tecumse engine that I was cleaning the carb for. It has not been used for several years. While taking the linkage off I could not see where the linkage with the spring end came off of under the linkage plate on top of it. I have been unable to find any proper way that this is connected. The engine is a tvs115 57002A 3035b. I’ve tried several different possibility’s but am not able to get it right

    Hi everyone,

    I have a Briggs & Stratton 15.5 hp. I have replaced the battery, starter, solenoid, checked all connections, switch, adjusted valves, flywheel key way/coil gap, etc. If I turn the engine by hand all the way to the left until it stops, and then it will start. However, when I turn it off and try and start it regular the starter gets hot and it won’t turn over. Does anyone have any ideas what would cause this issue. i have tried literally everything. Any help would be appreciated.

  34. Hello,

    I just purchased a Bonanza Mini bike it appears all original but the motor is painted an original orange color and on the engine cover spec plate it has the following numbers H22A 1314P then below this : 96 91404 can identify what make the motor is and year serial # model number and horsepower ? I think it maybe a tecumseh but I am not sure.

    Thank you very much .. Will

  37. Chase Standifer says:

    I have a White Outdoors LT1650 which I have been having trouble getting the engine to start. I don’t remember the exact symptoms now but after some googling it seemed like the issue might be the starter solenoid so I replaced that. I got the mower to start last fall before putting it away for the season and unhooked the new battery so I wouldn’t get any drain. This is spring I tried to start it with no luck, I would only get a click from the solenoid but nothing else and then even that suddenly stopped. After examining the mower I noticed that the diode in the alternator wiring harness was burned out. I ordered a new alternator and installed it. I also replaced the spark plugs at this time since they seemed fouled. I charged the battery for good measure then attempted to start the mower, again. I got some faint attempts for it to turn over and the starter gear was engaging the fly wheel then it suddenly stopped doing anything again. A quick inspection showed that the brand new diode had burned up again.

    I have two main questions.

    What could be causing the diode to burn up suddenly like this? I obviously have some electrical issues and while I can do basic wiring I don’t know enough to diagnose problems.

    Does anyone know what the correct diode for this engine is? I can replace the diode much cheaper than another $113 alternator. The engine is a Briggs & Stratton model number 42A707, type 2238E1. Thank you.

  49. Bryan says:

    I’m working on an old 80902 3hp Briggs & Stratton. The coil was missing, so I’m stumped because the warehouses ask if it was manufactured AFTER 6212310 (does this code mean December 31, 1962?) My code is 6222051. I know that means it was manufactured in 1962, but I’m sketchy about the rest. Every website I go to shows that the next two digits are the month, but that would be the 22 month of 1962! Does it actually mean May (5th month) 22, 1962? What does the ‘6212310’ code mean, if that’s the case? Please help!
