DragBoss Garage/Advanced Product Design: Carburetor Tuning Series: Adjusting Primary/Secondary Idle

[@mikeleschber33]

Thanks DB and APD! This is exactly what I have been waiting for.

[@DragBoss351Cleveland]

Your welcome. I will improve to with scene. Glad this will help you and others. Stay tuned for float adjustment

[@mikeleschber33]

@@DragBoss351Cleveland I have tried for years to tune my carbs and could never get them to work as I wanted. I have been able to get the idle to work doing what you showed here. I still have a big dead spot right off idle. I will be watching and waiting for the next episode!

[@DragBoss351Cleveland]

@@mikeleschber33 Mike that’s why I say knowledge is power. Now, things to thing about bog, throttle linkage position on throttle bracket, squirter size, cam color and position, secondary linkage, and or vacuum secondary spring to start. Float level next. Please share with other buds. 🏁💪🇺🇸

[@seanb250]

Great video, look forward to the rest of the series. Video posted to the porting group 👍

[@DragBoss351Cleveland]

Thanks Sean, I need to do a few things to make it better. But I think it will be very helpful . Thanks for posting to that group.

Yours is the coolest and nicest:) 775hp - That’s a beast

Hello Tim, I don't know where you find all these humble above average knowledgeable guys , your channel is a blessing for anyone trying to learn about performance, always appreciate you taking the time out of your busy schedule to share with us

[@DragBoss351Cleveland]

Trying to give back to help others. God provides, I keep the faith. I hope this series can help others with carb woes, get them back on the strip.Hope you liked the Cougar video.

[@terrygrover6440]

@DragBoss351Cleveland God surely does provide tim , yes I'm enjoying the cougar videos keep up the good work my friend 👍

[@DragBoss351Cleveland]

@terrygrover6440 🙏 amen. Way more on the way, same DBG station. Trying to schedule alignment

[@fbombcamaro434]

Excellent idea! Just some close up shot will make it even better. Like it feels people randomly go 2.5 turns in without seeing how far the slots are exposed and what is right and wrong. 2.5 turns on my holley is way too much but maybe not on an APD.

[@DragBoss351Cleveland]

Yes ,I need to get a better scene, will work on that. Your right, APD are 2.5-3 turns. And most don't examine the carb to begin with in regards to the transfer slots, or compare primary to secondary. Stay tuned

[@racemax3295]

we distribute APD in Australia, these videos will certainly help our customers understand carb tuning better.

[@DragBoss351Cleveland]

Thanks, Please share with your customers, yes, that is another reason APD is doing this. Please post my vids, have a whole playlist on race engine building.

[@billfioretti3013]

Thank you DragBoss, John and Randy. First installment in what promises to be a great informative and helpful series. So many competitors, street warriors and the off-road contingent struggle when it comes to properly setting up and tuning a carb or carbs. If I may offer one constructive suggestion, come in closer on the adjustments as they're being performed. I know you've inserted visual aid photos but active close-ups would be most helpful. Thank you again guys, and everyone please support The DragBoss Garage Channel. So much to learn and DragBoss has so much to share!

[@DragBoss351Cleveland]

Thanks Bill, I agree, I need to improve the scene, working on that. I do think this will make a big difference, and again agree with better close ups. See how it goes, may even repeat the vid. Have a float adjustment next, will be same scene, did it the same day. I will tell the guys the appreciation. I am trying to keep us learning all we can...Stay tuned.

[@ElvinLeadfoot]

Ohio Jimbo takes us down the Rabbit Hole:) Jim most people have never seen a Cougar as nice as yours Buddy. (No Joke) You’re is the neatest Cougar - Ever

[@DragBoss351Cleveland]

Thanks Elvin, she is a looker, Tim is my name, not Jimbo, that is my brother

[@ronniebraine9692]

Awesome info on tuning.

[@DragBoss351Cleveland]

Just getting started Ronnie

[@moparsareeverything1980]

Great info.....this will be an awesome series

[@DragBoss351Cleveland]

I think so too. Key: get the designer or specialist to explain topics. Fact not fiction. Try and mention Holley too changes too. Float level next. Thanks for watching Mike.

[@benrossbach6501]

Details deatails. The more we know the less it seems we know. Thsnks as always

[@DragBoss351Cleveland]

I get it Ben, just when you think you know something...

[@robertgardner1259]

Thanks DB, Awesome Video!!!!!

[@DragBoss351Cleveland]

Glad you enjoyed it

[@mikeg4163]

Hard to see what they are doing…better lighting and closer video would help.

[@JamesMiller-v4s]

Can you zoom in more? I don't need to see the couch on the left.

[@DragBoss351Cleveland]

Yes there are some minor issues, that I can improve on.

[@DragBoss351Cleveland]

I can improve esthetically.

[@mikeg4163]

Hey…but these are great videos…thanks for putting this together.

[@DragBoss351Cleveland]

@mikeg4163 they will get way better. Just starting out. I think we will remake this one. Short version, with way better visuals

[@Luke-jw6zn]

Why don't these guys provide any technical data on their webpage. If they produced more spec sheets on their products it would be super helpful and reduce the calls going in. The Web page is lacking.

[@DragBoss351Cleveland]

Always, trying to improve. Thanks

[@Luke-jw6zn]

@@DragBoss351Cleveland Yep I agree, amazing product. They have all that knowledge in their heads , it would help many folks including customers to get it on paper. Especially new builders and the young bucks. Thanks for the videos.

[@DragBoss351Cleveland]

@Luke-jw6zn your welcome. They will get better

[@kennyrmurray]

This should be a good series. No offense but I think next time John I think you said his name is (the bigger guy) should maybe explain it also it’s hard to see. I am already pretty good with carbs but I’m gonna watch this to make sure I’m not missing something. I had to relearn everything I forgot when I built my first car in 2017 from the early 90’s. I raised my kids so it was time to do it again! You also need better lighting. I knew what he was doing but for somebody trying to learn it was really hard to see. I converted mine to E85 and now I have to convert to blo-thru because I’m putting my procharger on very soon. Thanks for the vids!

[@DragBoss351Cleveland]

Good stuff for sure, few have commented on scene. Agreed. Doing on the fly, take what I can, be fun for me to do this. Been tuning carbs for 40 years, always seem to learn something though. Still raising my little Bossettes. Stay tuned to DBG, where you’re always seeing and learning something new.

[@kennyrmurray]

@@DragBoss351Cleveland yes always something new to learn!

[@petergehle4222]

Good stuff boys. Hi from Australia

[@DragBoss351Cleveland]

@petergehle4222 glad we can help you mate. 🇦🇺

[@tbirdracer460]

Thinking of changing up the new build To an Alcohol carb and it will definitely be a APD! Great video Tim!

[@DragBoss351Cleveland]

Thanks Tbird. Need to get some more vids going from APD.

[@johnnyhonda7576]

How do you tune the secondary power valve on a Summit 750 Vac secondary?

[@DragBoss351Cleveland]

I only know to ck. vacuum, and use one that lower than your reading.

[@grandville464]

How much of the transfer slot is showing at those 2.5 turns?

[@DragBoss351Cleveland]

I don't remember Darby, but should be about .025-30, thanks for the Super Chat

[@grandville464]

@@DragBoss351Cleveland I was just curious cause the old Holley’s especially the HPs transfer slots were all over the place and I know these new billet ones are positioned different, higher, shorter etc then them, is the 2.5 turns specific to the APD bodies?

[@DragBoss351Cleveland]

@grandville464 yes, 2.5-3 turns. Not sure on new Holley carbs.

[@cammontreuil7509]

Too many ask questions. Its like this. I like to go fishing. Ive put the time in to learn where to go. People just want me to tell them when and where and what to use fishing. That information costs me money and time and people just expect for you to give it out for nothing. Back in the day. I had many cleveland engines. Bought all sorts and different cams. Experimented. If you want to catch fish, pick a river and explore. I hate reading threads where people ask what cam to use. Buy three of them. See which one works best for you. Stop being lazy.

[@DragBoss351Cleveland]

I can dig what you’re saying Cam. If you want to go fast, learn how. This is a craft and you need to be a craftsman, and a thinker. I will also say that many guys ask me tons of Cleveland questions, I try and help. But no questions take one answer. That takes time, I think for me vids help. So with Cougar hopefully done, can start some of those types of vids. Get going on engines I plan to build. Vids of the engines I have done, hp and ETs. That’s what I did. Build engine, go faster, get more parts. Research and test. Hopefully this will help them to give best customer service.
