I know this great video is 4 years old but I wanted to add one tip I'd forgotten. That blue fuel vent line you see in the video....to cut that hole at bottom center, use a cheap hole punch. Carefully, use the punch to cut a nice, neat semi-circular hole halfway into the tubing. After installing make sure the hole faces down. I use small zip ties to tie each end off. And thanks for answering my questions below. I did finally get the fuel leaking into the air filter stopped but it's been so long I forgot how! :)

Very good video. You managed good camera work to show the parts clearly, and your narration is easy to understand. The only thing that would be a nice addition is to show how the throttle slide, needle, cup, and spring are removed and installed, and whether the O-ring on the needle goes above or below the clip. Thanks for a helpful, clear video!

The brass insert is not made to be removed. Some carbs it is. You need a new float needle if you want a new rubber tip. Polish the needle seat to make sure that it's clean and get a new float needle if you are worried about fuel bypassing that. If you want to know if it's leaking anywhere else, bench test it, let the carburetor fill by gravity and if it's leaking past that brass insert the carburetor will overflow.

Good video, thanks. I watched because I wondered it there is supposed to be an O-ring on the idle jet (the long one with 8 holes). There is a slot below the head which looks like a place for an O-ring. Mine had none and neither did yours, so guessing no O-ring is needed?

Best 54 video on the Net. Just wasted two hours looking at others. Question please: I've owned 54 equiped ultralight aircraft for 45 years. I know the 54s & 84s like my brothers. Currently, I have fuel vapor exiting the carb & dripping through the filter. Never seen that before. It cranks but that's it. Runs very rich. This from a 20hp, single cylinder, electronic ignition (Paramotor) Bing 84. I have done everything in my experience of 45 years including a new viton tip, checking float level, arms, cleaning interior crevices & all jets, checking the choke (now new), the slide, the idle air screw, adjused needle jet & main jet for cold weather, changed all O-rings & on & on. Any advice really appreciated. This has me stumped. Fuel filter new, lines new, fresh 98 octane fuel.
@TepcoCycleRepair4 жыл бұрын
Ok so I think You're looking in the wrong place. If you're running rich or getting excessive fuel back through the air cleaner it's a sealing issue at the cylinder. So either your reeds or rotary valve is letting pressure back through the carburetor. Because of this it picks up extra fuel in the carburetor because as we know as long as air is passing through the carburetor it will pick up fuel. so if you have air going in both directions through the carburetor you're picking up much too much fuel which could cause it to get blown back through the air cleaner and cause the engine to run rich if it runs at all. hopefully this will give you something else to check out and get you up and flying. Thanks for the comment!

@@TepcoCycleRepair Thanks Tepco. This is a very simple single piston. It doesn't use reeds or rotary valve. You might be thinking of the Rotax 503 or 582. The 582 uses a rotary valve. 503 is similar to what I have here. No reeds. I agree with everything else you said & thank you again! Anyway, I just pulled the entire carb. I bought a Taiwanese $39.00 Bing 84 knockoff a while back. Installing it now. Figured what the hell, can it be any worse?! Will let you know if it helps & if I blow myself up.

What about the brass guide for the float needle? Does it come out? Another video (different carb) showed it was removable and was the cause of leakage past the O-ring seal around the brass guide. Wondering if the Bing 54 is similar because I am having trouble with low fuel pump pressure. I know it's not a bad fuel pump because when I pinch off the the fuel lines to each carb, the fuel pressure goes up significantly. The float needles with rubber seat look good as far as I can tell. Is it possible to replace those rubber seats on the float needles, or do I have to buy the whole needle? Thanks for any help.

Thank you for this video. It was very helpful and informative. I pulled apart my Bing 54 and all looked clean and good. Is it necessary to have the air hose attached mentioned at 8:19 and 18:45? My Rotax 447 won't start with it on. Fuel starts leaking out of the air filter if I keep trying. I pulled off the hose completely and it started after a couple pulls. My hose is also solid with no air hole. Should I cut a hole in the hose like you have in 18:45? Thank for your help and this video. Finally got my plane started.
@TepcoCycleRepair4 жыл бұрын
They are vent lines and have to be open. I would highly recommend looping it like I did and cutting the hole the same way. Don't just leave them open as high velocity air passing the open hole could cause suction which isn't good either. Loop the hose and make the hole big enough like I did. You also don't want the hoses flopping around which is why the loop is ideal. Thanks for watching!

Is the pine sol pure pinesol, or some amount mixed with water? I plan to clean out my carb since my rotax 447 only goes up to about 5900RPM and is supposed to be able to hit 6500. (It runs fine otherwise, so I'm guessing something's partially blocked and not letting enough fuel in.)
@TepcoCycleRepair Жыл бұрын
It's pure original brand pinesol. If using it undiluted try to warm it up and don't leave the carb in for more than 20 without checking it. It can oxidize and start to darken ( it cleans off)

I had a single carb and everything ran good. Went to a duel carb and it has a really hard time starting. I have re jetted and even changed the needle jet for my altitude. It is hard to start and when I finally get it started I have to keep priming it to keep it going and it will only idle at 800 rpm. Way too low! I give it gas and it dies. Eventually it picks up in RPMs and acts normal and idles at 1800-2000. Any suggestions on why this is happening? PLEASE HELP!!

Did you go with dual carbs that are the same size as the single? I would think you would need to go down a carb size. Sounds like to much carb causing it to run lean. What are your spark plugs saying?
@michaelbartlett15893 жыл бұрын
Tepco Cycle Repair you use the same size carbs but jet it smaller. So each cylinder has its own carb getting the same fuel as the one carb for both cylinders but more accurate/ consistent amount with two carbs. Spark plugs look good.
@TepcoCycleRepair3 жыл бұрын
@@michaelbartlett1589 I would think the same size carb throat with leaner jets would cause a lean condition. I would say try the same size jets as the single. Here's why, with a single carb only one cylinder is pulling through the carb at a time, just like it has its own carb, so if the jetting was good with the single it would be correct for the dual. Try it, use the same jet sizes for the single for the dual.
@michaelbartlett15893 жыл бұрын
Tepco Cycle Repair thats interesting. But there is a jet chart for single carbs and duel carbs and it tells you exactly what you are supposed to jet it to. If that was truly the case the chart would say the same jet for either the single carb and duel carb. But I’m definitely going to try it just bc I’m curious.

Dirk Botha no problem I can help. First make sure your floats float and are adjusted right. Also be sure your float needle is good or new and the float seat is clean. Gas is coming out because the gas is not getting cut off when float hight is reached so it just keeps filling the carb. If your running this carb now it should be running extremely rich.
