Hi all.
Ive got my mini sprite running after 2 months.
Ive had new plugs leads /coil /dizzy /distributor/battery/alternator.
I’ve turned dizzy enough to get going and runs fine when warm.but still slight missfire on initial start up.is there a way to stop this.thanks all.you’ve been a great help so far

Is there more info on your ignition setup?

 

It could be ignition or fuelling, but it's best to start fault hunting with the ignition first. Do you have a timing strobe and/or dwell meter?

Is it a single cylinder misfiring, or a general hesitancy?

Hi all i dont have strobe or dwell
And it only pops on intial start so i can’t tell if its single pot or not.fuel is no issue as runs fine .
I think just needs tweek on timing as i only guessed by sound when turning dizzy.
Oh and how do you check timing with strobe.excuse ignorance but i had mini 35 years ago so technical is not my strong point.I think i did well just to get it started with many bashes and cuts to hands lol.

Old fuel, founded up plugs.

Clean, or new plugs, gapped correctly, fresh fuel, don’t just warm up and idle, warm up and drive to temperature.

The timing light "freezes" the position of the mark and allows you to line it up with the other marks. Steveson motor co has an ok video (not perfect)

You really need to get a timing light, it is not optional.

If you can get a timing light with advance it will be best.
