The Chevette is still on points and I'd like to convert it to electronic ignition, the promise of better economy, power and reliability all sounds good to me. I've seen a kit from this company www.simonbbc.com/powerspark-range for the Chevette for around £30 it seems cheap as chips, has anyone had any experience of these kits or kits of this kind. Any advice or help is much appreciated. Thanks Robin. |

Having looked over that engine, I'd say carb first. The dizzy is good new, and the points and condensor are good. Ok, so points aren't perfect - but I think it's fair to say that the carb need attention first:
-Electronic ignition will give you maintenance free ignition, but there's no need to touch points for 2000-5000 miles. Unexpected failure of the condensor is perhaps the most probable "stranded at the side of the road" failure, but I seem to recall that the one on there is a good brand, so it's not likely.
-You will only gain power and economy if the timing is all over the place with the points, but with this dizzy it's fine.
Carb:
I seem to recall that it was running a touch lean - I expect Dave sorted it, but if it's hunting and 'stuttering' about on part throttle cruise perhaps not. More fuel will give better power, probably without compromisng economy if it's running lean as it will be burning the fuel inefficiently.

Cool, I'll leave it. The carb was first on the agenda anyway, it isn't hunting although it is a bit flat when you floor it. It doesn't feel strong all the way though the revs.

If you unscrew the damper from the top and lift it up, you can gently raise the piston (there's a clip holding the damper into the piston - don't pull too hard or it'll be a pain to get back in. Ask me how I know...  ). With the engine at hot tickover, gently lift the piston about 1-2mm. This makes the mix leaner. If the engine revs up and sustains the higher revs, the mix is rich (raise main jet adjuster). If the revs drop, it's lean (lower main jet). If the revs peak slightly and then settle back to much the same as before, it's about right. |
