Lucas distributor automatic advance springs
Over 150,000, brand new bagged Lucas automatic advance springs. Probably the worlds largest stocks.
Sold as distributor sets, if the specifications are known, or alternatively by dimensions.
Please note that fitting a pair of originally specified springs to a tired distributor will virtually never restore the original advance characteristics. This is due to small amounts of cumulative wear in all the associated componentry i.e. spring posts, cam to shaft interface, advance weights & pivots, springs, & bush etc.
I commonly fit advance springs some 5 thou shorter than the original length to help matters. But, if you've got a lot of patience and a good strobe, you should be able to effect an improvement by some careful experimentation.
Alternatively, please send the distributor to us for a complete professional overhaul.
