No Spark at the plugs
« on: August 21, 2014, 01:27:59 PM »
Ok really getting stuck! Having FINALLY gotten the time to start sorting Kermit out I have run into a few problems. Thanks to the nice team at 500ricambi the new fuel pump is in and working, however I still have no spark at the plugs. I have put a new coil in, changed the plugs (NGK's), reset the dizzy, new points and condenser (points gap checked!) and shoved a new battery in aswell, I have gone through the ignition timing procedure for the TDC and still bugger all. I noticed that the HT lead to the first cylinder is a bit manky but surely I would still get even a weak spark? and surely a spark on the plug for cylinder 2? What the hell am I missing? I should add that Kermit is a 1974 594 cc. Any help would be greatly appreciated, thanks in advance!!

Do you have a spark when you open the contact points (use a screwdriver), ignition on, distributor cap off to do the check?
I have seen a few times that the new contact points/condenser have not been replaced correctly, it's worth double checking..

Hi Chris, yes I have checked and have a good spark at the points just not at the plugs?

Get some new HT leads or get a multimeter on them and see if there is much resistance in them. Careful you don't get a big nasty shock if they're very ropy!

Check the timing, Make sure it isn't out by 180 degrees

do you have wasted spark ignition(rotoress). the trouble is that i you have high resistance on one cylenders it will effect both. the other issue i have had is some new points need to be cleaned to work.

hopefully you will get your kermit working again.
