Some of these strange symptoms can happen if the gasket betwen the carb and
the engine dries, or leaks. I'm not familiar with your machine. But, some
small engines, I've had to take the carb off, put a little Permatex IIb non
hardening on the gasket, that helped.

We had a Mantis garden tiller which worked well for a number of years but it
finally wore out this spring, when we bought a new one. It worked well for
the spring tilling then rested in the garage for the summer. I wanted to do
some tilling recently and it got tempermental. I spent several hours working
on it over the last few weekends but it just won't work.
The status is that it will start on full choke after several presses on the
fuel injector bubble thing. I let it run for a few minutes to get up to
operating temperature but it shuts off when the choke is opened. If I try to
accellerate with the choke closed, it also dies.
I've tried adjusting the carb screws in every possible way, the plug and
fuel filter are good, and the muffler screen is clear. I drained the gas
tank and re-filled with a new 2-cycle mix of the proper ratio. Any ideas on
what else to try before I give up and take it to the shop?
A million things spring to mind but Mantis has a one year warranty. I'm
sure they will be happy to adjust or fix this.
