its running very rich and i sealed all my air leaks gapped my plug and it wont rev high at all it just 4 strokes and bogs down really bad and my clip is at the top what else can i do?
Yes you are very right Nougat after having 3 of the NT carbs on my engine I can see that they will need to be letted down a little they all run like pulling 2-3 spark plug wires of a V8 engine and floorboarding it... just a bunch of buck-in and no rpm's.mapbike, the throttle needle clip doesn't do much to adjust fuel flow at WOT, it's for low and midrange. Good call on the float height, but to really get these dialed in, you have to downjet, either with solder and a drill, or replacing the jet with a smaller one. After you do that, you can probably move the needle clip back down again.
These carbs take Bing jets, right?
you wouldnt love the ones I have, I have been rebuilding carburetors for years on just about every kind of engine you can imagine weedeaters, chainsaws, tecumseh, Briggs, Honda, chevy 2G, 4GC, Quadrajet's, the old carter AFB's, Holley's ect. and these are the first new carbs I've see that I have had so much grief with, I ordered 2 engines from BGF, I've used both carbs on the one engine I'm running and I thought maybe I just got a couple bad carbs that have issues with the floats or the needle & seat so.... I ordered another new carb. from you guessed it BGF got it today put it on and guess what fuel level in bowl running so high that it's flooding just like the other 2, I have not reset the float level in this last one yet so this could be the problem... I find out tomorrow, but it is just blowing my mind that I would get 3 of the very same carbs that started off brand new and all three of them have faulty Floats or needles or seat or all of the above....????????????? I am just really scratching my head over this situation dont know what to think right now... one of them was running so dang good for about an hour or so and then BAM...! the flooding started all over again with it.....! Maybe I need to buy a carb from someone else and see if maybe I'm getting some junk carbs from that BGF guy....! I just dont know at this point...!send them all to me. i love these carbs.
