Toro GTS 20332 (bought it 12 months ago) won't run

This is pretty much the same thing that I was told by a service shop. My primer bulb is built with a hole in the front center which I though was odd. the next season when I fueled it up the fuel poured out through the primer bulb hole. The guy told me that the bowl is similar to the drain in the toilet tank. If old fuel has dried up on the seal it allows the new fuel to flow through and run through the primer bulb. Of course, this is an indication that it was not properly drained at the end of the first season and naturally* voided the warranty (not a fan of TORO). He volounteered to flush the system for around 80 bucks. I found it ironic that my almost 400 dollar lawn mower lasted one season before needing an 80 dollar repair that is easily said to not be under warranty. In the meantime my now fifteen year old Murray with a B&S continues to run...sure it sometimes takes *more than one pull*, but the fuel doesn't run right through it...fuel I left in during winter with a stabilizer in...hmmmm (did I mention...not a fan of TORO)

I believe that Toro Guarantees to start 1 Pull, was gas left in it all winter?, If so this is'nt covered under warranty, cause gas is to be ran out or dumped out at end of season this will prevent any gumming up of carb . did you completely disassemble carb? does it have a primer on it, those gskts need replacing, clean out the jet in bottum of float bowl,small holes,sometimes missed and remove and check your needle/seat to make sure that when float drops gas runs out then lift float up and gas should stop. hope this helped you,another thing spray carb cleaner in carb and pull over and see if it will start that way enough to keep running with choke to see if it will **** gas into it
