I hope you can help to diagnose the cause of the trouble I am having starting my car after it has not been used for a few days. It is turning over as I engage the starter, but unless I spray starter fluid in the carbs it takes a long time to fire up (more than a minute). I have a federal '72 plus2.
The good news…
My Stromberg carbs have been cleaned and checked over and the needles adjusted to their richest setting by a competent mechanic. My battery is less than 1 year old and has 13.5v when tested off the car. Electronic ignition has been installed by a competent mechanic since the starting problem began. This did not improve or worsen starting.
The bad news…
The choke must be left half out when driving the car or it stalls at every stop. The starting and stalling problems started immediately after a Dave Bean water pump conversion was fitted to the car. Prior to that work the car sat unused for 6 months.
A mechanic has suggested that the problem may be the fuel pump siphoning fuel back from the carbs…???
Thanks
Chris
