Anthony Scott 2 Posted April 4, 2019 Share Posted April 4, 2019 Hello, I recently took the u/c off my Acrowot XL. The Roto 35 powering it is mounted inverted & the plug cap took enough impact to tear the cap from the HT lead. There is no other damage. The Roto uses an unusual plug which is flat topped so a conventional plug cap is not suitable. A new CDI unit is £120!!. Can anyone help with re-connecting the plug cap to the HT lead, please?

Ultymate Posted April 4, 2019 Share Posted April 4, 2019 Just Engines list replacement caps but you may have to change your spark plug to suit Quote Link to comment Share on other sites More sharing options...
Anthony Scott 2 Posted April 4, 2019 Author Share Posted April 4, 2019 Many thanks F1 for the link to BigPlanes, they are a new name to me & offer better value than Perkins. I have identified an alternative plug but not the CM6, it is too small in diameter. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted April 4, 2019 Share Posted April 4, 2019 The NGK replacement is the BMR6F, Just Engines sell both these and replacement plug caps to suit. £15.50 for the pair! Quote Link to comment Share on other sites More sharing options...
