Thread: I built a 350.......

Tweet

Ok, so I leaned out the part throttle one step back, pushed my initial up to 22 and it ran good, still cranks too! Seems like I just needed more timing, oh it's a 1412 performer carb. I didn't clip the hood pins and I flipped my hood back! Man, I was pissed! Oh well, it was fun. I only got to try part throttle, it used to start pinging around 4000, so I swapped to the 1 light and 1 med spring, that puts me ay 42 degrees at 5500 rpm. I haven't been able to open it up since I put it in the s10 so I'm hoping for good results.

42 degrees is too much centrifugal advance for a 350. You're gonna hurt some parts. Drop it back to 20 at the crank and 16 on the weights like I suggested 2 hours ago.
