I am having trouble finding a manual for a gasgas txt 249cc 2001 model any suggestions?

Engine size should be stamped on the back of the cylinder (249cc, 124cc, etc...) As far as the year, see if a dealer service department can help, or call Yamaha USA customer care.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Stator is volts AC ,isolate the wires from system check AC volts from one stator wire to the other until all combinations have been noted.you are looking for 40 or 50 volts in the pairs of stator output wires.weak spark could be volt regulator.or weak or dirty connections in the wires or at battery terminals. also running lots or ad-ons can **** the life out of performance.Am thinking of changing my name to check ALL your fuses, because they are not all in the box.

It may be a failed keypad or control board, but more likely it's a simple failed door switch or loose or broken door switch mount.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

I would strongly suggest checking the door switches first.

Also, there should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

you should have an idle screw on the carby, you may need to adjust that to boost the revs for the right idle speed
