These Master Tech videos are awesome. I've bookmarked everyone of them that pertains to my car. I also have the paper versions that I've made into a binder/book. Just like back in high school.

harmony Posted May 30, 2021 Report Share Posted May 30, 2021 I'm fortunate enough to have 4 carbs for my car (Carter B&B EV1). I've bought rebuilt kits for two so that I have a spare in the trunk ready to go if I need it. My particular carb has an internal dashpot. So it actually looks like it has two accelerator pumps. When I installed the plungers with the leather boot, even after soaking them, there is still a lot of side play. When driving, I find if I give it quick acceleration, just after making a slow corner for example, I get nothing, If I don't feather the gas pedal immediately the car will quit. I've had the suspicion that the leather boot isn't expanding perfectly. I'm just thinking that since your car hasn't been used too much that perhaps that leather boot on the accelerator pump has dried up a bit Keith Quote Link to comment Share on other sites More sharing options...

Simple green for instance with badly discolor some white metals quickly. My wife used real in jewelry at our. Store. I used her cleaner more than she did. Ditto on not using Simple Green. I ruined a carb in the ultrasonic cleaner using Simple Green. Stripped off whatever protective coating was on the carb, and the exposed metal kept growing white powdery junk. Personally, I'll stick to Gumout from now on. Quote Link to comment Share on other sites More sharing options...

Sorry...what I meant is no more dunking carbs in ultrasonic cleaners for me. I cleaned the spare BB I had with Gumout, acetone and elbow grease, and it worked out fine.

Squirt the heck out of it with Gumout, or dunk in acetone. The Chrysler tech bulletin on carbs even says to keep water away from the carbs, or they do exactly what mine did, which is oxidize and jam up the holes with crud. Should've read that first. I've tried simple green, pine sol, acetone, and lacquer thinners. I blow out with air after soaking over night but I still seem to have slight residue, inside the carb parts like in the float bowl etc. I've thought about getting an ultra sonic cleaner for years. Sorry Keith I don't mean to be drifting away from the topic. 1 Quote Link to comment Share on other sites More sharing options...

We have common dishwashing soap here called "Real". dishwashing soap will also do. Using carb cleaners and other acidic chemical formula beats the idea of these cleaners. Fluid in ultrasonic cleaners is just for dirt to be able to flow away when subject is bombarded and resonance occur. Water could be used but no one wants water left in carb, so alkaline fluids ( opposite of acidic solvents) will not affect carbs. If any soap is left in small channels after thoroughly blowing with compressed air is left, when mixed with fuel, they get neutralized.

Dodgeb4ya Posted May 30, 2021 Report Share Posted May 30, 2021 Oil Eater works excellent in the Ultrasonic box. Cleaned a lot of parts including carbs. Excellent for cleaning grease out from under the nails too. Quote Link to comment Share on other sites More sharing options...

Maybe a cup per gallon of water. , mostly it was time, heat and the buzzing of the ultrasonic cleaner that sis the trick. SG is safe for aluminum, especially the aviation type of SG.

greg g Posted May 30, 2021 Report Share Posted May 30, 2021 (edited) I bought a gallon of Barrymans carb soaker. It comes in a paint can type container and has a plastic strainer for small parts. Over night in that and stuff comes out amazingly clean been finishing up with brake clean and compressed ait. Gloves and safety goggles strongly recommended. https://www.walmart.com/ip/B-9-Chem-Dip-Parts-Cleaner-w-Basket-and-Armlock/226784113?wmlspartner=wlpa&selectedSellerId=15321&&adid=22222222227311868762&wl0=&wl1=g&wl2=t&wl3=390072145599&wl4=aud-430887228898:pla-829702952085&wl5=9005095&wl6=&wl7=&wl8=&wl9=pla&wl10=125215384&wl11=online&wl12=226784113&veh=sem&gclid=EAIaIQobChMIirWt-LTy8AIVy8DICh138g2XEAQYCCABEgIUf_D_BwE&gclsrc=aw.ds Edited May 30, 2021 by greg g 2 Quote Link to comment Share on other sites More sharing options...
keithb7 Posted May 30, 2021 Author Report Share Posted May 30, 2021 (edited) Test drive results: Dead spot just off idle is gone. Great results. I am losing a some power at high rpm. I can feel it. On another web site a member mentioned that the Holly fuel pressure regulator will cause a leaner condition. If that’s true, maybe I’ll set the float to be a little richer. Maybe the bowl can’t deliver enough fuel at high load and rpm. I’ll play with my timing a bit first. I been screwing with it a fair bit over the past few days troubleshooting. Getting closer!

keithb7 Posted May 31, 2021 Author Report Share Posted May 31, 2021 (edited) The more I dig in I, keep finding more interesting stuff. At the red arrow, on the top of the accelerator pump spring, the round brass retainer cover was absent. Under the screw-in cover seen at the green arrow. Down in there is an accelerator pump discharge check ball. The ball was there but someone had a fine small spring jammed between the screw-in cover, and the check ball. That spring would have been forcing, retaining the ball down into it’s seat. According to my paperwork its not supposed to be there. More test driving. It keeps getting better. High RPM still feels a little off. During test driving I am hearing a little backfire on occasion too. Seems to happen only on deceleration. Not often. Adjusting timing seems to have no effect on the high rpm stumble or a backfire. Might be lean on fuel? Adjusting float had no effect either. Hmm. New points and condenser are on the menu. Those parts in the car are well worn and of unknown time in service. Replacement is part of my overall ground-level reset. Might as well put those in next and see what develops. Then go from there.

The ball should be 3/16" dia. Sounds like whoever was into that carb wasn't sure about things so you might want to check the dia. of the ball at the bottom of the accelerator pump chamber under that clip. That one should be 5/32" dia. They might have switched them by mistake. Quote Link to comment Share on other sites More sharing options...
DJ194950 Posted May 31, 2021 Report Share Posted May 31, 2021 Is that a small BB check ball resting in that channel to the right side of the green arrow, behind the accel. pump? That May be the one that sits under the accel. pump under the left side of the bottom of the hole in the accel. pump bore in a small recess? Maybe just the pic.? Depends on size as mentioned- they are Not the same. DJ Quote Link to comment Share on other sites More sharing options...
greg g Posted May 31, 2021 Report Share Posted May 31, 2021 Where is your acc. pump linkage set. If I recall there is a choice of three position notches which determines the pumps length of travel. Is your step up plunger and rod moving smoothly and traveling it's full stroke. Quote Link to comment Share on other sites More sharing options...
