Hope my first post iis in the right place!
Ok I run a 300hp bam / hybrid motor in a mgzs180 shell.
The car I am told used to run perfect at tickover etc but when I got it the tickover is bad . Once started u have to keep it revving to stop it stalling , after 30 seconds it will sort of tickover but very rough and almost hesitating almost stall then pickup again. I the car stalls then u have to pump throttle like mad to get it running. With a tiny bit of throttle all is fine and once on the move the motor is great.
So any ideas where to start sourcing the problem would be appreciated
