So I have the 1.8 L engine which looks like it was injection but now has twin carbs so my understanding is that the timing for a 1.8 is 4.5 BTDC but does that need to change because of the now carburettors? And yes I'm having problems starting!

F.I. calls for 27 degrees at throttle, which never works for carbs in my experience. You'll be looking for 29-32 degrees. Too low and it will bog out on acceleration and chug-chug in cruise. Too high and you lose torque, run HOT, and your engine will sound like a sewing machine. Also, make sure your not starving for gas with too small main and idle jets. With carbs, go rich and go advanced. With experience you will find the sweet spots.
