Re: Lawnmower Engine Starting Tips??
I still haven't gotten my mower running for longer than just a little bit. I still have to take the carb off again and take the yellow plastic fuel tubes out/apart and see if they are clogged or anything. Or maybe see if there's that valve thing Al mentioned a while back.
mtaman02, for your mower I have some answers. A spark plug wire is only one wire that goes to the plug electrode. The body of the plug is grounded through the engine block. Some mowers have a little metal "stop" tab on top of the head right next to the spark plug. (my 2hp b&s didn't have it, my 3hp one had it). You just flip it over (it is sort of hinged) so it touches the top of the plug. This shorts the iginition and the ground so no spark is produced. If your engine doesn't have a tab, you can short the top of the plug to the head with a screwdriver (the metal shaft of) to stop the engine. You probably want to hold the insulated end of the screwdriver to prevent getting a nice shock. I don't think it would hurt you (I've gotten a spark plug shock a few times) but I'm not totally sure, besides, it doesn't feel good to get shocked. In any case, don't wire a switch in series with your sparkplug wire/cable. It is not necessary and probably not a good idea. Also, usually you can pull the choke out all the way out and it will die in about 5 seconds or you can try putting your hand over the carb opening if there is no air cleaner on there, although that may take longer and might not work. Last, by Engine Zone Cable I assume you mean throttle cable? Last edited by sanddrag : 11-07-2005 at 17:25. |

Re: Lawnmower Engine Starting Tips??
Ok if your engine has an air cleaner assembled to the carb you would want to make sure the screws assembling the too are tight other wise for some weird reason it will not allow a little bit to no fuel to go to the carb - I found that out the hard way but yeah make sure the carb & choke is clean take it apart and just spray the appropriate cleaner into it / WD-40 =) it worked well for me and has not upset the workings of the motor.
As for the spark plug it sounds like its too much work to mess around with I was just curious if I could just hook up like a switch to cut the spark off. Shorting this that and the third is not my kind of fun. I could try holding my hand over the carb but i really don't like the idea of having my hand next to something that gets extremely hot let alone moving. the engine zone control cable is how the manual describes it, there is no throttle cable on it - the throttle adjustment is seperate and is actually mounted on top of the carb and choke assy. for this particular motor however i removed it since it was broken and was unable to obtain a new one due to the mowers age so what i have done is just run the mower at a high rpm to keep it from stalling out when cutting alot of greass. the engine zone control cable is basically your engine cut off / emergency brake - in case anything god forbidden happens On the Tecumseh Motors the Brake is assembled on to a bracket which has like a bike cable attached to that end (its spring loaded or so thats what how it apears that way when you release the handle bar it shoots the brake out) the other end is attached to a handle bar which you pull back so that you can start the motor. - I'm sure you already knew that but I figured I try and explain the main function of the engine zone cable. The throttle cable on some mowers is attached either right under the handle bar or on the carb itself so that you can increase and decrease the mowers speed. which as i said before do not currently attached. |
