You are correct on the learning part. I went in and changed the closed setting to open for the cold. Mine is getting better with every start. Also I cycle the key twice before starting that just gives it a double squirt.

Closed to open on what?You are correct on the learning part. I went in and changed the closed setting to open for the cold. Mine is getting better with every start. Also I cycle the key twice before starting that just gives it a double squirt.
Question for those with some miles on theirs. Mine doesn’t want to cold start to save it’s life. It’ll start and die probably 2 or 3 times before it’ll start, idle really low, and slowly rise to around 1000rpm. Is that something that will self learn and get better the more I drive? I haven’t put more than 10 miles on it since the conversion. I’ve tried adjusting the coolant temp enrichment up to near 200% and it doesn’t do anything for cold start in my case. Should I just drive it more? The problem I see is that it isn’t learning below 160° so how will it learn?
Otherwise, it’s a drastic difference with how much better it runs.
IAC at cold is worthless. Has to be checked at 160Check your IAC position at cold. Sounds like your initial position set is incorrect.

Do you have this sniper manual? On page 56 is how to enable/disable the 0deg to 160deg open/closed loop or adjust that temp. I didn't change the temp I just changed if it was enabled or disabled. If it don't work out it is easy to change back.Closed to open on what?
My IAC over 160 is about 5%. Cold start it’s at 100%.IAC at cold is worthless. Has to be checked at 160
CorrectMy IAC over 160 is about 5%. Cold start it’s at 100%.
Fuel prime to 150% really helped out a lot, Thanks! I put about 20 miles on it tonight, it runs so so much better than it did with the carb.Correct
Has anyone had issues with backfiring upon initial setup and drive? I only have drove it in first and second down my neighborhood.
I set up my timing but not IAC. I’ll give that a tryDid you ever get it to idle correctly and set up your timing and IAC before you drove it?

I have a HEI DUI dizzy do you still want the timing at that?Go back to the manual and see the section about IAC.
You don’t adjust the throttle with the screw on the butterfly. You do it with the Wizard setup then adjust IAC after.
If that settles in 2-10 then drive it. See what’s what.
Timing 7-10
Timing is critical and is the #1 reason other than an exhaust leak for backfires.I have a HEI DUI dizzy do you still want the timing at that?
What did you do to fix it?I had serious backfiring issues. It was the the advance on the HEI.
I rebuilt the unit and lubed the 'bushing well' with high temp wheel bearing grease. The spark was grounding through the dissy shaft and it turned the old lube to gum.What did you do to fix it?
