Hey Pelicans,

Don't wanted to get flamed in the 911 forum, so I came here....

I have a brand new carburated Goodwrench crate motor in my 911, which runs smooth as glass at idle. The problem is that it's been stalling on deceleration (occasionally), and cutting out when accelerating (not heavy acceleration because I'm still breaking in the motor). It just loses power for a moment, and you have to rev it to recover. It seems to be most pronounced between 2nd to third gear changes. I'm definitely thinking that it's a fuel delivery problem, but I could use some additional input.

I replaced the 50 PSI pump intended for fuel injection with a more or less generic parts store model at about 5 PSI, because 50PSI is too much for a carburator. Another very irritating issue is at takeoff. This thing jumps all over the place, and it feels like the 915 is going to be ripped out of the car. Sometimes I can feather the clutch enough to minimize it, but it's not 100 percent reliable. I'm thinking that all of these issues are related to fuel delivery

Resolved all the overheating issues which fried my heavily modded 350. Now I just need to resolve this issue, and this car will be awesome. BTW, this problem was also present with that motor too.

Any relevant advise is appreciated. Thanks!
