Yeah i've adjusted the idle screw on the tb but it hasnt done anything realy its till wanting to rev higher then what i set it on the tb..As for leaks i've had a good look about and cant see/hear anything also if it was a leak it would stay at a certain rpm, were as mine settles back down to 950rpm after 5min sat stationary then it will work its way back up to 1200rpm after abit longer its pissing me right off lol Also when its idleing high the smell of Vpower is unreal as if the coke is stook on? im thinking its the TB my self as there is a thrmovalve inside the tb witch the water warms up and if thats not working it wont shut the choke off..thats my gess anyway lol just dont want to buy one thing to buy another thing lol
