Hello again. I'm the guy that bought a 620T with starter isuues some 2 weeks ago. I ended up getting the starter rebuilt, new battery, weight racks and wheelie bars in time to go to a pull last weekend. Had a blast, but a poor showing overall, no surprize. Now the work begins. I've ordered Petronix electronic ignition and coil, and am changing plug wires, plugs. I want to rebuild the carb, but I can't read what comes after "DLXT" on the ID plate without removing the carb. I want to order the kit, but won't have time to remove the carb till next week. Does one kit fit most of the possibilities, or are they pretty specific? Unfortunately, the serial number plate is missing, so I can't really say what year model I have. Also, can anyone recommend the right AutoLite plug to take advantage of the new ignition? I have read that you can widen the gap to around 0.030? Thanks in advance for your advice.
