I have a weedeater rider with a tech engine. I spent $165.00 to get it tuned up back in May 2006. I used it about 15 times this year. Roughly 40 hours on it.

The reason why I spent $165 to get it fixed was it kept on stalling after I ran it for 3 to 4 minutes. Well it's happening again. The oil is okay, the sparkplug is new the filters look good and I keep it clean.

It stalls if I'm just riding the mower or cutting grass/leaves. It starts up fine.

Any suggestions or ideas? I have changed the gas even have NEW gas container with NEW gas. The fuel filter is not clogged, looks new.

Any advice would be great.
Thanks
P!

New gastank? What about a new gas cap? Try it without the gas cap and post back...
As for the fuel filter not being clogged... looking at it tells nothing... oem filter?
