robindeakin Posted October 29, 2011 Share Posted October 29, 2011 i mounted my brand new 180cc redhead engine and have been tuning my carb, i didnt want this engine to meet the same fate as my last, i have fitted a temperture gauge and have tuned by the book, although there is no way to hold full throttle and adjust high speed needle without possibly losing an arm, i just made settings a shade rich on both screws to be on the safe side, so the settings are 3/4 low and 1 high, CHT at idle 150cc, does this sound about right? i was surprised i used 3 litres of fuel in what seemed like a short time has anyone else tuned a walbro Quote Link to comment Share on other sites More sharing options...
morgy Posted October 30, 2011 Share Posted October 30, 2011 Hi was that you i saw at newhaven with the camper van..... Seymor stopped to say hi but i had to shoot off to get home..... We had a great days flying.... Sorry no nothing about walbro carbs.... But i think tuning the high end needle is a stop start operation.
