    With the engine not running there should be spring force trying to pull the throttle open.

    422707-121401 sump gasket

    Some engines do this but I am not familiar (don't remember really) it has been a while since I have worked at one of the opposed flat head twins. The best would be to follow the linkage and see if there is a link or lever to do so. Even the service manual has no clear picture of the control. If...

    422707-121401 sump gasket

    You stated you were able to bring it back to idle by using a wire -- does the governor are try to pull it back to idle? If not there could be one of two issues.

When the engine is running the governor should pull the carburetor closed, when you start the engine is there any force opposing the sparing? Trying to close the throttle? Can you hold the governor...

    Engine shakes while engaging blades

    Blown head gasket a common problem on Breaks & Scrapem singles especially the 28 and 31 cube engines. Some overeducated engineer thought they did not need a headbolt in the pushrod area and therefore it is a long distance between the two head bolts. Quickest way to check for a blown gasket is to...

    M-ZT 52 Stops running when hot!

    When it shuts down have you checked the antifire solenoid (if it has one) in the carburetor bowl? Sometimes when they get hot they will not work properly and close. May have to check for a missing heat shield or fabricate one.

    54 inch riding mower just clicks, won't start

    You say it "just clicks when the key is turned" Is that to the run position or start? The fuel solenoid and other relays will click in the on position, the starter solenoid when turned to the start position will only click if it is bad, because the internal contacts are corroded and don't make...

    Somthing to think about. A V twin engine fires the same as the two cylinder John Deere. One cylinder fires and the other fires 90* later then there is no power for 270* turn of the crankshaft. John Deere had an issue using single barrel carburetors because the first cylinder was lean and the...

    Clogging bagger

    Are you running the engine "wide open" and is the speed set at manufactuerers specification? Depending on mower deck and mulching blade design it may not produce enough air flow for a bagger. Is the deck clean and the boot and tube clean? Is the screen clean in the bagger so air can get out...

    Oil for new cub cadet XT1 LT46

    You did not say what engine is on the mower. Kohler had that issue but it has been to long I don't remeber the fix.

    Here a spark plug, there a sparkplug...

    These were usually OEM Honda installed plugs. As I said I could not explain the why, I can only say what happened and after replaceing the plugs with Champion had no more problems. They only reason I can put on the problem was there was a problem with the resistor in the plugs. By the way the...

    I cannot explain the why. I can only say what was done and how it was fixed. The only explaination I can think of was the plug was partially fouled. Yes I don't understand why the timing was changed, only that it was. And that by changing the plug the issue was corrected. I replaced the plug...

    Here a spark plug, there a sparkplug...

    This was especially Honda push mowers Yes more than one, would be hard to start, pop back thru the carburetor, pop out the muffler, plus pull the cord back. Changed the plug mower would start easily and run good.

    Honda gx690 low power

    Honda just loves to play games with the small engines. Their old ignition modules needed to be grounded to kill the engine, new ignition modules need to be grounded to run. Yeah I found out the hard way.

    There may be an Igniter used on this engine according to the service manual. Best to check them before condeming the coils.

    b&s 12.5hp flathead riding lawn mower engine smoking - looking for suggestions

    Most pistons used in small engines use at least three rings. Two compression and one oil. Athough the second ring is regarded as a compression ring it also does a little oil control. If the engine has been fed clean air the compression rings will show little wear and the engine will have good...

    I was wrong. electric start still not working.

    Remove spark plug wire, turn mower on side -- with carburetor up -- very carefully watch the bolt in the center of the crankshaft, turn the blade, if it is not true and goes in a circle the crank is bent. Sometimes it is easier to have someone pull the startter rope while someone watches the...

    B&S seized 5.0 on push mower

If that is what happened the connecting rod seized to the crankshaft, the connecting rod overheated and deformed causing the bolts to...

    Convert GAS Briggs V-Twin to DIESEL?

    Don't think it is possible. Not enough compression, the block is not strong enough to handle the compression increase, the rods are too weak, no way to put injectors in the head. As for a turbo many farm tractors have not used a turbo the AC D19 was the first, then other manufacturers started...

    Toro Titan MyRide 60 inch no start

    Most manufacturers but not all put the seat switch in place to kill the ignition when you get out of the seat. This is so you can't get off while the engine is running unless the pto is disengaged and the control levers are out or start position. This is so you don't get run over or chopped up...
