Hey everyone I wouldnt say im a newb to nitro cars/trucks but I dont know everything and I learn new stuff everyday..... Now my problem is im running a kyosho inferno neo ST race spec with the kyosho .25 engine. Lately after my engine warms up and car is running at good temps if I go full brake on my Tx after letting go of full brake position my engine starts to race up like crazy but goes high rpm then drops back. I cant thing of anything i checked to see sometimes when the servo goes to far it causes a snap back but i cant see any snap back. any help would be greatly apreciated Thanks. MY rc is running with not too much smoke but its def not in the dead red lean section. and after a long stretch if i dont apply the breaks the engines revs down nicely.

Another problem is i cant idle for more then 5 mins if im not appling gas but that i think could just be a really low set idle screw

Assuming everything else is correct and working properly, this is the fix...

Make sure you have a rubber band around the carb to act as a throttle return spring. This should eliminate any play you have in the linkages. Seems like this may be the problem. Hope it helps
