    I'm in need of some advice on what to look for in order to get my ride-on tractor to stay on. Here is the whole story.

    * Tractor sat unused for 12+ months, including a new england winter. No fuel preservatives or winterizing was done.

    * When I went to start it, battery was dead. I had it recharged successfully.

    * After starting running for 10 minutes engine (without deck engaged), engine stalled. I was unsuccessful at getting it running again until I added engine starter fluid in the carburator. Also topped off fuel tank (about 4 gallons were put in)

    * Used the tractor for 1hr (without deck engaged). Tractor speed felt sluggish. It stalled a couple of times but I was able to restart it.

    * On another day, I started it and it stalled. Noticed the fuel filter was empty. I suspected a fuel problem so I changed the pump and put in a new filter.

    * Now when running (deck unengaged), the battery light sometimes stays on. When I engage the deck, the battery light always turns on. When a little bit of load is placed on the deck, the engine stalls.

    * After stalling, I can get it started but it won't stay on unless I push on the choke level all the way up.

    * The speed of the tractor, even deck ungaged, is noticeably slower.

    I think the key to finding the problem here is the battery light turning on and the slower speed. It is indicative to me of a fuel problem but I can't find the problem yet. The spark plugs were new before the tractor sat unused for 12+ months. I will probably replace those today as well. In the meantime, any more suggestions??

    It would be nice to know what engine is on this tractor (model and spec numbers), It sounds like you need to perform a good carb cleaning as outlined below.

    Take the carb. off then tear it down, Spray carb. & choke cleaner with the straw through ALL ports, passages and jets then blow it out with compressed air if available then re-assemble....

    Once you get the engine running properly the battery light may go out.
