Finally! These are the FR5's
Taylors 135 degree boot works great with headers.Nobody local has wire I want. Ordered two sets of Taylors from Jegs (One 90° boots and one straight). Took advantage of the 20% up to $50 off sale Advance is running until midnight and bought a Proform 750 mechanical secondary by getting JEGS to price match, also a nice fuel inlet, Lokar throttle cable, JEGS return springs, and a crank socket for my degree wheel.Not gonna put the carb on until I find the problem, but it was too good a deal to pass up.
Will update after I get the parts and get wires and plugs installed.
Thanks for all the help!
Usually...close all idle screws , then turn them out each exactly 3/4 of a turn. No matter where they end up...they all want to be the same amount. Fire it up....see if it idles, if not raise them to one turn out each and try to start it again... If you have a tackometer , for instance on your timing light...once running , put it in gear with the e brake on and a tire wedge....you can open the idle screws a hair more each till the rpm STOPS increasing, there can be a fine line...so pay attention to rpm and also know that sometimes you might want to set them just a hair under max rpm so that you can keep the stink down.Now I need to start tweaking this carb a bit. I set the choke with a credit card size gap fully closed.It runs pretty good, but it seems like it's loading up at stoplights, the idle drops a few hundred rpm. Also sometimes when I let off from 40mph or so it's kind of sputtering.
I've never had a carb with four corner idle adjustment. What is the best way to go about setting it?
From the factory settings, I tried a quarter turn lean on all four and the idle went up, and i backed it down. It seemed like off idle response was quicker, but it acted like it wanted to die if I was coasting. I tried a quarter turn lean just on the secondaries and drove it 15 miles home, but it started losing rpm at the last stoplight, so I m moved it back to stock when I got home.
I don't have any jets yet , but where should I start to try and get it to run good on the street?
Sorry, It has been a long time since I messed with a Holley type carb, and I have much to learn.
Gonna go pull the #1 plug and see how it looks...
See...lol , so the FR4's work , still check for specs, and you didn't need that fat an idle.Got home from work and cleaned up the FR4's and reinstalled. Started over with the 4 corner screws, set them 3/4 turns out and cranked it...
Two pumps of the pedal and.....flooded it trying to fill the bowls I emptied last night checking the t-port....Damn!
By the time it cleared up the electric choke had opened all the way from the key being on, but it fired up and idled stone cold. It's never wanted to run under 150° without a choke before.
I noticed a little eye burn so I started leaning it out a hair at a time, and rpms started coming up. I stopped at just under a half turn and it smelled right so I left it there. Messed around with the throttle cable adjustment to take out some slack and took it around the block. Realised it was idleing a little high when it warmed up, and readjusted to a tiny bit of slack. I took it out and when I got to the access road I rolled into it. Spun in second just a bit and then broke them loose for a second going into third as I slowly laid into it...hmmm...never done that before!
I looped around on the next exit and got into it a little faster. Shift points were good but it kicked down into second from third about half throttle so I pulled in a parking lot and loosened the Lokar kickdown cable until I had about a 16th gap with the cable pulled out and the throttle wide open. I pulled out and made a right onto the feeder going uphill. Rolled into it pretty good and was pleasantly surprised! No bog, no stumble or surging, and I got past the speed limit VERY quickly! I let off and got on the highway to go two exits down to my favorite T&T spot mentioned above. There is a VW dealership and then a mile down is a Dodge dealer, I nailed it at both from 50mph. Proably made a VW buyer think twice and sold an SRT Challenger, lol...
Got to the next light, waited on green, eased over the train tracks and floored it! It broke loose but I stayed in it, then into third they spun again. I couldn't look down at first, but when I let off I saw 110mph and started looking around for cops.
What a blast!!
Thanks guys! It has never run this good before.
Gonna pull plugs in the morning and take a peek.
Have to order a tuning kit with jets and power valves, and maybe a cam kit, so not able to play with the tune too much more yet. I wanna get my A/F meter in first to save me guessing, but I am real happy with the improvement so far, and can't wait.
Btw- timing right now is 19-33 in by 3000...I can at least play with that until I get a day off to go have bungs welded in. Gonna try and map the curve and see what I can tweak.
