    Running lean on light throttle

    So I messed with the transition slot it was quite large actually so I lowered my idle a little making it smaller and it cleared up a lot of my problem. The squirter I think is still too large cause it I hit it hard it goes stupid rich. And her down a little. But over all much better already

    Running lean on light throttle

    I’d rather rich then lean,I want it to sit around 13.5-14 which it does just not as often as I’d like. The ifr’s are much bigger than stock at 43 and it’s curbed a lot of the right off idle issues. And I’ve looked up the issue before and came up with ifr again. I just got the truck back on the...

    Running lean on light throttle

    it runs 13:1 when I say go a certain throttle then let off a little it stays in acceptable range. But when I hit the gas farther even super slow it goes lean it’s hard to explain

    Running lean on light throttle

    I didn’t test total right now cause it’s too late in the day. But I don’t think it’s a timing issue. I just drove it home and it was running lean everywhere all of the sudden. So tomorrow or the next day I’m going to rejet and just see what happens

    Running lean on light throttle

    I appreciate you’re help but I’ve triple checked everything and just had the dizzy out 20 min ago to double check and it just doesn’t like 14 ish degrees it is currently sitting at 20-21at idle. And yeah it sits about 34-36 total

    Running lean on light throttle

    It’s not unheard of to run at 22° distributor is set up correctly I’ve checked and double checked that more times than I’d like to admit

    Running lean on light throttle

    So my engine wants 22° of timing at idle it won’t really run too well anything underneath that and with mechanical advance it’s already at 36° so I am not running a vacuum advance

    Running lean on light throttle

    I had completely forgotten about the transition stop being a square I’ll have to look at that I know I did in the past but I cannot remember the results! I’ll have to pull off the carburetor on my next day off and take a peek

    Running lean on light throttle

    It also doesn’t help that I have a 273 rear axle ratio in combination with the weight of the truck and what not makes it more complicated than if it was a super torquey gear

    Running lean on light throttle

    Yes I’m aware of all of that and it is done correctly. I appreciate the help with that. I’m fairly sure it’s not the Excelerator pump system because if I give it a pretty heavy pedal it does not have any hesitations or leanness Because it around 13 five but just trying to leave a stoplight in...

    Running lean on light throttle

    So I’ve done a bunch of research I have a 350 and a holly quick fuel 600 vacuum secondaries carburetor right off of idle my AFR gauge Will go 15-16-17 to 1 with only light throttle if I jam on it it leans out for a split second which makes me think it is the Excelerator pump squirter but I’m...
