Hi Scott,
I¡¯m not sure what a minor rebuild of a Dell¡¯Orto might consist of, but perhaps it falls short of what is actually needed.
Following Kirk¡¯s line of questions, did your R90S idle before the minor rebuild? What prompted you to do the minor rebuild in the first place? Without more information it would be hard to troubleshoot the problem.
I¡¯d suggest that you do a proper full rebuild (and hope that your wire probing didn¡¯t damage anything).
Here¡¯s a link to Snowbum¡¯s Dell¡¯Orto rebuild info that will take you through the job.
As a side note, way back in a previous lifetime, I used to do form of minor carb rebuilds on a ¡®52 Chevy pickup I owned. It consisted of starting the engine and holding the throttle open to get the RPMs up pretty high and then spraying some long forgotten brand of aerosol carb cleaner all over the carb and into the venturi. Didn¡¯t really do anything, but it was quick and dirty and gave me a feeling of accomplishment¡ for ten seconds, but hey, I was 23 years old.
Mit freundlichen Gr¨¹?en/With best regards,

Hi group Happy New Year!
After a minor rebuild of my Dellortos, I am unable to get any kind of idle. I¡¯ve removed the carbs and using a thin wire ensured the idle circuit was clean and open. I¡¯ve also used carb spray to soak carb passages. Still no idle. I¡¯ve checked points gap and valve clearance. All seems within spec. I¡¯d appreciate any suggestions on what I¡¯ve missed or anything else I can try.?
Thanks for any input.?
