Hello everyone

[Englishbdog#1]

Ok ,I am at my wits end , my son got me an 80cc motor kit brand new and we installed it on a beach cruiser, put oil/gasmix in and it wont start so i bought a new h-p carb on it ,still wint start so I check spark ,no spark, I get my meter and perform some trouble shooting,magneto reads good ,kill switch seems ok , the cdi ,nothing between the black and blue and from what o see on you tube it should have a reading ,it says of it doesn't the cdi is bad so I buy another cdi andetrr it before I install it and this one also says OL o install ir anyway and check for spark- nothing so I thinkots just a streak of bad luck and order another one this one also reads OL still no spark I am an electrician so I know how to read meters I dont think 3 brand new ones can be bad anyone have any idea?

Chinese HT engine won’t start? Well let's see what might be the cause of your problen. Electrical 1. Improper wiring. Black magneto wire to black CDI wire, blue magneto wire to blue CDI wire. White…either remove or isolate. 2. Kill switch defective. Do not hook it up until you get the engine...

Here's a diagram of it...
