Title: Weak Spark D7.
Post by: A10 JWO on 21 Nov, 2018, 16:20
Weak spark but running. Checked the points which look very good, they were at 10 thou' now 15 thou. NGK Plug looks ok albeit fitted in about 1980. Tried another spare which was worse. The HT Cap is modern NGK. The condenser was probably fitted when we won the world cup. Don't really want to throw £££'s at it yet as I have two expensive projects on the go. Any advice would be good. Last on the road 1981. Thanks.

Worth trying reducing the points gap.

The Wipac bulletin below explains why.

This may explain why you found the points set a 10 thou.

Had a change of heart, the Bantam is now on ebay listed for sale in Essex, 1 bid £900, 6 days left. Looking at a Daytona 500. : )
