so i shot the car tonight on the parkway did a third gear hit at 3500 in my auto on a 75 nx wet kit. bottle preasure was 950 psi air fuel was 12.6 question is when i hit it it sputter for a spilt second and then it hit nice and hard is that normal for it to sputter for a second? i was thinking i need a higher psi fuel pump for the initial hit i never had this prob coming out the hole and this was my first roll on spray

 

I know this is a stupid question but did you purge the system?

 

yeah i purged it

 

Seriously what it sounds to me is that the jet might had been a little obstructed and then once the obstruction moved it hit hard. I doubt it had anything to do with a rolling run or anything like that. Change your jets make sure to look at all the stupid ****, like clean hoses, clean connections. But a new fuel pump will never hurts.
