1600 cvh in a mk2 fiesta...
Can come to it one day, and it'll fire first time and start everytime there after, and run and drive spot on
Other days... it'll just turn over and over, not had the car long and not currently using it but would like to track down the issue, most parts are new or recent looking, all wiring is visually ok, just fit a new ign module (it was physically damaged)
Anyone any ideas ?, or anything common on the cvh's that makes them a pig to start ?
Cheers

What Carb has it got? Is it auto choke? I forget what the CVHs had one them. The ford VV carbs are notoriously plop. Auto chokes can play up too.

Weber tldm with autochoke, which appears to be working as it should
Has brand new mech fuel pump, to replace the badly fitted electric facet
Haven't gone to far into it, but must be missing something simple, hoping someone has had a similar issue
Cheers

Has it got the condenser box on the dizzy? They're renowned to be a weak spot.

Check the pcv circuit the valves used to stick open and they would never start, as a trial you can blank the manifold off and leave the camcover vent pipe open
