Need some an ext help please, ~ trying the overnight soak procedure it still wasn"t running very an excellent but at least it would run for longer prior to cutting the end so I at some point got that key jet the end < the one above the float> with straightforward out an equipment and replaced it, all jets are an extremely clean. My initial settings were idle 1&1/2 transforms out from all the way in and additionally the high side settings the same yet no matter how I try to readjust them ns still get very choppy sound indigenous the exhaust, so once again I would appreciate any help.thanks
1 1/2 transforms out is typical for the low speed, but change the high rate for best performance. The variety of turns have the right to vary native one to another. Is this unit old enough to have actually points? What is the engine model and also code?
