We shouldn't expect DLE to go to all that trouble. All us "buy and fly" newbie crybabies should fully equip ourselves with machine shop and fix it ourselves like "real" hobbiests of old.We should just buy metal and build our own engines from "scratch" like real modlers. I apoligize for the sarcasim but really tired of the "buy and fly" and similar references used here on previous posts. I have three DL50's that have run perfectly for several seasons,but if I had bought a DL30 with this problem I wouldn't dissassemble it,I would send it straight back for a refund or get payment back on my credit card. Not because I have no skills(used to custom build Holly carbs for drag cars) It's the manufacturers problem not the customers.
