Need help with Traxxas Revo 3.3 tuning
Ok, im fairly new to rc and nitro and made a trade for a used revo 3.3. Ran good, started to make some upgrades and now it won't run. I've been workin on it for 3 weeks now and nothing helps. It idles very high. high enough to spin the spur gear. Reset the needles to factory and it wont stay running at all, starts and dies immediately. If I richen the LSN it will idle. Sometimes it will idle for a little bit then it sounds like its flooding out and dying. When I have it warmed up if i throttle it more than about 1/4 it will die immediately. If i ease on the throttle it smokes like crazy and starts to stumble and dies. I thought it was an air leak so I changed the block and bearings, tried 2 different carbs, 2 gas tanks, 2 exhaust pipes. It is also dripping oil out of the ez start. Changed backplate and havent run it yet so I don't know if that helped. To me it seems to be running really rich, but if I lean it out it doesnt run at all. Please help!
