Well i bought this 426 about 2 weeks ago and its been nothing but problems. Ive got most of the problems sorted out but 1. Heres the deal... When i first got the bike we couldnt get it started. Found out the plug was toast. I went and bought a champion "racing" plug. Put it in. Bike starts great several times. At most 3 kicks cold. Then all of the sudden yesterday it takes me an hour to get it started after wire brushing the plug off. Today it wil not start. Ive kicked and kicked. I checked spark and the plug wont spark. So i take a NGK BR8ES that i have out of my jet ski and put it on the cable and it sparks like crazy. So then im sure its the plug. I take the champion plug that wont fire on the bike over to a 1960s snowblower and plug it in, it fires like lightning. Atleast 10 times brighter than the bike. I dont understand, is the ignition always this weak? why wont the plug fire on the bike but on a 5hp snowblower like lightning. What is the best plug for the 426?
