Help please

Post by sijrayner »

My NC24 will not run on 4, the carbs have been cleaned, I've checked for sparks but the front right cylinder refuses to fire. The plug is wet with fuel, I'm no mechanic but when u get fuel and flame why oh why do I not get fire. I took it to a shop and they are about to give up as well. I don't want to scrap it but it's heading that way so any idea could help.
They say they cannot find any info on coil resistance etc. Everyone knows about NC30's but no info for 24's

Try switching the coils around and see if the problem transfers to the other cylinder

You have three coils that fire, measure a couple and use the readings to test the suspect. If readings ok then check wiring to the non-firing coil. Still no luck then maybe dud ignition unit. NC24 ignition unit has 4 outputs as opposed to NC30/35 that has only 2 that drive double ended single coils.
