Hi all
Twin Stromberg 150 CD carbs.
My car has always run on the rich side and would start in winter well (using the choke never increased the revs hardly)
I have rebuilt a second set of carbs and using a colortune the car is getting better MPG and running well.
I used all the choke assembly parts that were with the rebuilt carbs and it looks like the choke bars are raising the pistons and the cam is working the fast idle .
When starting the car in the morning, it is sometimes difficult to start. Uses lots of very short bursts of the starter as the pinion disengages straight away and it sounds like it is nearly starting.
When it does start the choke only seems to make a bit of difference, as it was like with the old carbs and also when the choke fully pulled out the revs drop off a bit as it did with old carbs. When hot it starts on the button
I seem to remember driving various Heralds years ago that the choke would increase the revs quite a bit.
The cars has had recent new plugs, points, condenser, Ht leads, coil, dizzy cap, rotor arm.
Any tips on getting better starting when cold much appreciated.
Cheers, Dave
