Is this the Dynojet or Cobra Stage 1 kit you bought on ebay? You might have the needles off by groove or more. I was off one groove and that's how I came up with the name drkngas

Where do you have the e-clip installed???

ross · July 10, 2011, 04:33:59 PM

I dont even know what is this e-clip.I don't know if I instaled the shims in the right place.The jets are easy to install once you take out the carb's but instructions for the shims are not to helpfull.

Well the e-clip should be in the 3rd notch down and you are saying you are getting raw fuel out the pipes?

tedkraus · July 10, 2011, 05:31:09 PM

are the carbs flooding? or just moving too much fuel? if they are flooding could be a float or some valve is stuck, if they are moving to much fuel as other said check e-clip position.

I'm with Ted here.. I think you have a stuck float.. I could be wrong, but that's where I would suspect..
Be careful.. IF it is a stuck float, then you have put a lot of gas into a cylinder.. That fuel will drain down past the rings and into your oil.. IF this is what has happened, once fixed, you need to replace your oil and filter again..

Yes I install the dinojet kit .They ofer it in 2 options :Main jets only 105's or Main jets 105's Idle jets 42's ,shims and D tool.I install the full kit.Before was blowing gas from front right cylinder.Now is Blowing gas from left 2 cylinders.

i think there is gas in your oil.. i would not attempt to start it at this point. check your oil, see if it is full of gas or smells like gas very strongly. drain oil ASAP.

Not to sound insulting. When I installed mine I remember e-clips, needles, jets but not shims. I thought Dyno and Cobra were the same. If it was running fine before the Dyno kit, I'd remove the carbs and retrace your steps.

good point - the stock setup has shims. if you are running an adjustable needle, take off any and all shims, they are not needed and will make it waayyy too rich.
