[QUOTE="JASON_l_l_666, post: 1999609, member: 349759"] I just got a HSP Tornado with a SH .21 with it I ran it in with 4 tanks, rich at low rpm after that did one more tank a bit higher rpm then I tuned it and ran it normal. after another 4-5 tanks it stopped wanting to idle I spent about 3 hours running and trying to tune it. I got home pulled the air filter a found a small amount of dirt around the carby, so I pulled the whole motor and carby apart and clean it put it back together. I have run it rich and I have run it lean and it does the same thing as soon as the revs drop to idle it cuts out straight away. Runs a little better but still will not idle I am thinking maybe new piston and sleeve but Im not sure what sort of compression this engine should have, compression doesn't feel much different from when I first run it but I could be wrong. Does anyone have ideas on what it might be. One more thing can anyone recommend and cheap .28 or or bigger engine that revs high i was looking at these ones. http://www.rchobbies.com.au/store/product_info.php?cPath=28&products_id=22841&osCsid=fcb58c2863f73b53d905f75efac44824 http://www.rchobbies.com.au/store/product_info.php?cPath=28&products_id=13976&osCsid=fcb58c2863f73b53d905f75efac44824 http://www.rchobbies.com.au/store/product_info.php?cPath=28&products_id=36564&osCsid=fcb58c2863f73b53d905f75efac44824 I would like to stay with pull start [/QUOTE]
