Hi,

I've just finished overhauling the head on my 1990 mk1 cabriolet. Put a new 270 hydro cam with heavy duty springs.

She's been driving great, but it's a bitch to get it started in when it's cold. The engine turns over but doesn't take. When it does start it chugs and just gets going if I keep the pedal to the floor. After that it's all fine again?

Any suggestions what might be causing this? Thanks, Ed
