I as same problem with mine. I stil got injector down. Before I start it I turns ignition on keave heat plugs get hot, knock igniyion of and back on and fires it up. Once fired a couple seconds later u gear a extra little rev. Its like the choke kicking in. If that little rev dont kick in it smokes and you got to hold acceleration to build revs up to pull off. Bearing in mind mine is still running on 3 and not boosting
