I find myself in a situation where I am now solely responsible for mowing the lawn. I have this ride on lawn mower and although have successfully started and used it once, cannot now get the accelerator to work. Starts fine but there is no response to acceleration in either forward or reverse. According to my ex-husband, when I posed my dilemma to him, "the fuel tank has a hole in it at the outlet and when you start it you need to lift the bonnet and manually override the throttle cable on the carbi to give it more fuel/revs for 5-10 seconds then once warm operates normally"!!! Can you believe it? I have absolutely no idea what he is talking about do you? If so, I'd really appreciate some assistance as the lawn is out of control! Thanks, Jennifer :-)

Get some thing to patch the hole on the tank, go to your local e auto parts store they might have some thing, or get some of that mighty putty you see on tv and patch the hole as for the throttle cable you need a mechanic to fix that.

Safety and Preparation
Serious injury can occur if the engine or mower blades accidentally start while you are working with lawn tractors. To prevent this, drive the Murray lawn tractor onto a flat work surface and disengage the mowing deck cutting blades. Engage the parking brake to keep the mower from moving; chock the wheels with a wooden block or brick. Adjust the mowing deck to the lowest position. Turn off the engine and remove the key from the ignition. While not necessary, you may even wish to disconnect the spark plug wire from the spark plug.
Mowing Deck Removal
You must remove the mowing deck on a Murray lawn tractor to gain access to the belts. Remove the adjustment rod hairpins, followed by the adjustment rod pins from the front left and right sides of the mowing deck. At the rear on the left and right sides, pull out the retaining hairpins and slide the mowing deck suspension links from the adjuster plates to separate the rear mowing deck from the frame. Remove the blade control rod stud, including the hairpin and washer, from the top of the blade control lever shift linkage at the left rear of the deck. Remove the front hanger rod, including the hairpin and flat washer that hold the rod in place. Loosen the belt guide retaining bolts with a socket wrench and remove the engine stack pulley belt so you can slide the mower deck out from under the tractor
Transmission Drive Belt Installation
Slide the new transmission drive belt between the engine stack pulley belt guides, over the belt guide plate and under the engine stack pulley. Fit the transmission drive belt around the top engine stack pulley. Push the free end of the transmission drive belt up through the transmission shifter hole in the lawn tractor floorboard. Slip the transmission drive belt loop over the transmission shifter. Pull the transmission drive belt down through the transmission shifter hole. Fit the transmission drive belt around the transmission drive pulley and tighten the transmission drive pulley belt guide retaining bolts to hold it in place. Fit the transmission drive belt flat side around the idler pulley. Slide the idler pulley onto the idler pulley stud while holding the belt in place. Tighten the transmission idler pulley retaining nut with a socket wrench to secure the idler pulley to the idler pulley stud.
Mowing Deck Drive Belt Installation
Pull back on the right side mowing deck mandrel pulley spring-tensioned belt retainer. Guide the new mowing deck drive belt around the right side mandrel pulley and release the belt retainer. Pull the drive belt spring-tensioned retainer away from the mowing deck idler pulley, guiding the deck drive belt around the idler pulley. Fit the mowing deck drive belt around the left side mandrel pulley and under the rear mowing deck cross link rod between the right and left side mandrel pulley. Slide the mowing deck under the right side lawn tractor frame, reconnecting the deck to the frame in reverse order of removal. Engage and disengage the mower deck while driving the mower to test the belt for proper operation.

Sounds like you have some sort of seize up problem in your deck assembly. Have someone help you with this check, start your engine, engage the blade or blades, and have someone watch the shoot from a distance to see if blade or blades turn. if not then your problem is in the area of top pulley and blade or blades. You may need to replace or loosen the pulley to blade shaft. Sometimes this part is repairable where you can replace bearings or bushings and sometimes the whole unit needs to be replaced. Look to see if there are grease fittings on this unit. Try oil anywhere it will flow down in between areas that may be seized and work on loosening up the pulley blade assembly. If this doesn't help, go to some of your local mower repair shops, they may be able to sell you a used part. Remember to bring mower information with you so they can help you with the correct part. I hope this has been helpful to you. GOOD LUCK.
