Not running very well

Ok I got the car out the garage for the 1st time in 6 months and she started up first time. However it will run perfectly for about 30 seconds the slowly cut out so I'm thinking there's only about a gallon of petrol in it that's about 6 months old so I'm hoping it's that. Has anyone had any similar going on's after being stored up for awhile?

I dont think its that uncommon for the fuel to go stale and run really bad ...

Petrol starts to go stale at around 4 weeks so at 6 months it may have started to go waxy. Get some fresh in there with a fuel system cleaner. We put a fuel preservative in the tanks of machines we service at work as most of the time they are coming in for their winter service and wont be used for 3 months.

What a tit. Turns out to get access to connect my broken break pipe fixed I had pulled the pipe off the dump valve and not re connected it derrrrrr

Lol you sound nearly as bad as me, I have to double, triple and quadruple check things because I always forget to tighten something up lol
Your wideband will come in handy for stuff like that mate because you would see the air fuel ratio would be off
