This morning I took it out for a drive to let it stretch her legs and just when I was about to pull in the driveway it died. Then it wouldn't start had to crank and crank and give a little gas and it started and got it up in the garage. Any ideas what it could be? I"m thinking spark plugs been on for around 1500 miles and the same ones it was on it's break in on before the tuning. I'd check them but gotta go to work so just looking for any other possible causes incase thats not it.
Thanks

how would it flood though, I took it out and drove it like 10 miles and was pulling in the driveway and it died

I just replaced plugs and took it for a drive and it still wants to and did die. Idle fine in garage warming up then take it through the neighborhood and stop and the idle is real low like 500 and barely limps running but will run great if given throttle. Could it be throttle adj? I didnt change anything would it just move on it's own one day?
