Mycountry87 Posted April 6 Share Posted April 6 Hello, I have a tomahawk st I think with a pro 18 engine and no matter what I do it either idles and doesn't rev up or doesn't start I use 20% nitro fuel and have set the idle to 0.6mm 20240406_154505.mp4 Quote Link to comment Share on other sites More sharing options...
wolfie1 Posted April 6 Share Posted April 6 (edited) You either have it too rich or lean turn the hsn 1/4 in 1 direction and try if it wont start or its worse go back to the original setting then turn it 1/4 turn in the opposite way you turned it the first time failing that try a new glow plug and start again. Once you get it running its just a case of adjusting the needles a little bit at a time till it runs right, there is many many videos on you tube describing this Edited April 6 by wolfie1 Quote Link to comment Share on other sites More sharing options...
