wierd startups after spraying Here is the basics of my kit and my problem.
I have a dual nossle NX wet kit (pics in my fquick) and I spray a moderate 50 rwhp shot
anyways here is what happens...... I spray it
(runs great) drive a little. park it.
Then when I go to restart it It will crank but not fire the first time or start funny
Then it will always start the second and then run fine
what could cause this I have some ideas but i thought I would ask you guys first
I havent checked my plugs in a while but the car runs and idle's fine other than when this happens
Oh yeah and it only happens when I spray it

It always starts up on the second try....just not the first.....But this only happens when it just got sprayed

The same thing happens to mine occasionally after I spray, if it dosent start up on the first try I crack the throttle all the way open and it always starts then.
its fuel left in the intake manifold from the wet shot, its normal, mine did the same thing, because when i sprayed a pass, and just drove down the return road and parked it, it would start real slugish the next time then be ok, and it only did that on a spray pass, i hear its a very common and normal thing
since the fuel has to pass through the intake some if it is left in it and next startup it will be really rich.

Thanks alot guys!!! 
Yeah that is what i figured was the problem and im glad to hear Im not the only one that has experienced this 
I will just make sure to leave it running longer next time before I park it or just not spray it if i plan in parking it shortly after......
Now that I think about it I bet it is just fuel that has not been vaccumed out of the line..... I mean there has to be a little fuel left between the noid and the nozzel after is has been sprayed because it is not flushed with oxygen after it opens...... If anyone follows what I am saying........Im guessing it doesnt help that my nozzels come from the bottem of the intake and that might be why extra fuel is hanging around.
You can see what i mean
