Found your site and have a quick question! I have a T230 which I've had for many years. The other day while using it, it shut down. I could get it to restart, but it would shut back off. I found that the primer bulb was damaged, so I switched it out.....still would not work. I found that the fuel filter was no longer attached, so I purchased a new filter and replaced the lines...still will not work. I pulled the carb, cleaned it out/off and put it back on....still the same. What I have found is that if you hold it upside down (fuel tank on top), it will run. When you position it as if you were going to use it, it shuts down. For some reason, it will not pump fuel on it's own. What do I need to do to get it to work again?
