Please don't shoot me if I am in the wrong section. I have a 1990 suzuki LT 500 R quadzilla. I have replaced the stator, carb has been cleaned, I have spark, it is getting fuel because the plug is wet. Trying to kick start this beast is quickly tiring. I have tried pull starting it to only get a couple of backfires. As far as I can tell I have spark and fuel. I have tinkered with 2 strokes for 35 plus years and this one has me stumped. Thanks for any help .
