Okay I have a carb of a TS400 cutoff saw Tillotson 279D410 there is no Adj for the High end. Before long I plan on putting the roto-butcher to the ports and was eying this carb ( I like it because it has a built in choke) or should i keep an eye out for a 044 carb this will be going on a 026. I have much more reading to do so this is a future project
