A final round of engine tuning! Decided to set the idle mixture today as the engine was very obviously running rich. Got the gunson gastester out and it verified the rich running by showing 3.5% CO. After a bit of tweaking of the idle mixture control on the AFM we got this down to around 1.2-1.3%. It’s not going to be 100% and it can be fine tuned at the MOT test before SVA.
Wasn’t in the mood for much else after the fuel pipe off the tank started spewing petrol all over the place. Replaced the cloth covered stuff with some 3/4″ rubber pipe I had in the parts bin. This was a tighter fit and also found a more suitably sized hose clip. Figures crossed it will be fine now!
As it was such a nice day it seemed like the perfect time to take the car for a little spin (on the driveway at least!)
Me driving the first round (mixture not adjusted) and Richard driving second after the adjustment (but the neighbours had returned so he had to be a bit more careful not to take out their car!)
