62-tr4-DK Posted May 21, 2022 Report Share Posted May 21, 2022 Hello Chaps! Just a general question... basically I have worked around it with adjustable spanners.... But what size are the small nut and bolts which clamp the carbs together as well fixes the returnsprings on the spindles? seems to be around 6.5 in metrics and well very small in imperial? Just wondering really :-) Best regards Niels Peter Quote Link to post Share on other sites
RobH Posted May 21, 2022 Report Share Posted May 21, 2022 (edited) 4BA I believe Niels. British Association was a thread widely used for instruments. It is actually metric in dimension. https://en.wikipedia.org/wiki/British_Association_screw_threads Edited May 21, 2022 by RobH Quote Link to post Share on other sites
Charlie D Posted May 21, 2022 Report Share Posted May 21, 2022 Always worth getting a couple of BA spanners ( 2BA and 4BA). I think they are used on most Lucas electrical parts of most British classics. Charlie. Quote Link to post Share on other sites
stuart Posted May 21, 2022 Report Share Posted May 21, 2022 (edited) Definitely 4BA and as stated a small 2BA/4BA combination spanner is a very good tool to have. Like this https://www.ebay.co.uk/itm/133957363871?hash=item1f307b289f:g:6IYAAOSw75hhr9hD Or even a cheap set BA Spanner set Stuart.
