Hi guys, my gem has a problem with the heat.
If the car been sitting in the sun, say 30/40 degree heat.
I go to drive it and it drives till i get to the next street after that it cuts out.

My foots still on the gas but the car like clongs out.
even some times it stalls.

Some times its worse than other times.
i'll be doing 80 km's and it will just cut out.
I switch it on and off and its fine.

Some times it'll keep doing it?

anyone got any idea's?

it only happens when the car been sitting in the sun and hasnt been started all day?

i got no idea what it is guys?

my email is joeysgem@hotmail.com

With Temp's like that it is usually a fuel " vapour lock ", had this happen a couple of times to me also, ended up being that the petrol cap wasn't breathing properly and the fuel vapours where pressurising the petrol tank. Even though the Fuel Return line ( under highier pressure ) from the carby (Nikki type) is suppost to help prevent this from happening under normal conditions it can and does still happen Sad

i'd say before u drive it next in the middle of the day, take off the petrol cap and release all the fumes then drive n see what happens
