Another question.....My original type Holly back draft carb has developed a leak. Gas is dripping from near the gas line connection. I removed the carb and re sealed the nipple what the gas line attaches to with form a gasket #3 thread sealer. It says on the bottle that it will hold up to gasoline. With a mirror I looked up and can see the gas dripping from around that big flat head screw which holds the carb together right behind the nipple that the gas line attaches to. Is there a internal leak and this is just an easy way out for the gas? I tried to tighten that big flat head screw while the carb was out too, but it was already tight. Do you think it might be time for a rebuild? Did I just answer my own question? Carb was rebuilt about 5 to 7 years ago. Thanks, Randy

Obviessily a 49-51 Merc carb. Ive never seen one leak from that bolt hole.You must be leaking gas from the bowl or theres a crack from the fitting hole to the screw hole. There shouldn't be any gas in the outer cover. The bowl is sealed from the outside cover. ken ct.

After closer examination, I think that you will find that the fuel line adapter is leaking around the threads and the gas is traveling to the screw before it drips down. A new gasket may fix the problem, but you will probably have to have an insert made to accept the threads of the adapter. The pot metal has probably deteriorated and the threads are not holding the adapter tight. Tom

The Holley 885 carbs are very sensitive to warpage. I've found several that were warped so bad that they leaked from several places on the float bowl.

Rand,all you have to do is replace the inner bowl section with another plus all the gaskets to do this,its a little tricky if you've never done one. I can give you another bowl section BUT have to know wich one you have. There are 2 diff ones . Either the inlet threads are 1/8" pipe thread or a bigger hole which is sealed with a gasket and very fine thread (i'll get the pitch tomorrow for you) Just pay for the shipping and the gaskets . ken ct. 1-203-260-5945 cell.

Thanks so much for your generosity Ken! It is indeed the carb with the small fitting. I have two other cores that have the bigger fitting to compare it to. I took the carb off the car again yesterday to give it another look over and redid that fitting with the yellow Teflon tape and it seemed to make a good tight seal without over lightening it. and sure enough it still leaks. I mean really leaks. Seems if it leaked this bad that I would be able to see where its coming from? Would the warped bowl show to my naked eye? I think that I will just send it out to Dayton Parts Co. for a rebuild for 300 bucks? Merry Christmas to me Ha Ha! Randy

I dought if D.P. will absorbe the cost of changing the bowl its a major part in there and really nothing can be done with that problem its washed out 1/8" pipe threads short of replacing the inner bowl.What yr Merc is this off of. I have a 49 that I redone a couple of yrs ago and never has been sold. A 50 is diff and a true 51 is diff again. I would take $125 for it if your interested if that would help you. Also not sure which thread is on it,i would have to check it . ken ct

I also doubt that any re-builder will use your leaker as a core. If I were you, I would accept Ken's offer of the replacement bowl and have him rebuild your carburetor, or buy his replacement if it is for your year Mercury. The yellow Teflon tape is for sealing natural gas fittings, not for sealing gasoline fittings. I do not know of any thread sealant that works well with the current blends of gasoline. Tom

Ken...my car is a 50 Merc. on the top of the carb is a little bitty "50" also. The 2 core's also have that 50 on top. The carb on the car has the little gas inlet hole and the other two have the big inlet. I wonder if the two core bowls are any good? Not sure what to do at this point. funds are short now and I will keep you in mind in the near future. Thanks so much for your help and offer. Randy

I'll look and see if I have one with the small hole. You can have it for the cost of my shipping.Yr would not matter 49-51 as all you are going to use is the inside bowl.I'll send it complete so you can see how it comes apart and goes back together.Use long guide screws with cut/off heads to assemble top cover. When its bottomed out it must not rock front to back or its NOT seated right.Its really a bit*h to get on correctly. Call me for more info. 1-203-260-5945 cell. ken ct.

What exactly is the difference between the 49/50/51 carb? I have the 50 carb on the car now.. Can the bowl just warp by itself? how do I check it? Your right about being a bit*h about getting the thing put back together correctly. I tried it with one of the two cores that I have. How do I check it for wrapage? id like to try it on the core that I have apart. Is it some thing I can see with my eye? Thanks a bunch! for your help Randy

Just for kicks...I saw this in a junk yard in Durango Co. last year. Didn't know they put Holly's on what ever truck (bus) that is.... Randy

Cant see the 8:23 pic. Looks like that one is on a 6 cyl and has a govener on it (not useable for you).A 49 carb has an uprite throttle lever and pushes opposite to a 50 or 51. 50 has a throttle lever that points down (not up). 51 has same throttle lever as a 50 BUT late 51 has the choke mechinizm attached to the intake manifold (not up on the carb). Some early 51's used the 50 carb. So theres a late + early 51 version. I will still give you a complete core with the small thread hole you need in the bowl for the shipping cost. What I would do is call Gina at Daytona parts 1-386-427-7108 and ask her if she could sell you 2 sets of gaskets for Merc carb. Tell her I sent you. Im not sure what the shipping would be on the carb,but just send what ever is on the PO shipping label. I think its too high for a flat rate box will have to use a bigger box for carb.

That looks like an International Bus and they used a Holley concentric carburetor until 1958 on some engines. Several other manufacturers also used the concentric carburetor. Tom

Ken I'm a bit confused... Why do I need two sets of gaskets?? Not looking for any freebees.. How much should I send for your core? How do I tell if the 2 cores that I have are any good first? Tks, Randy ask her if she could sell you 2 sets of gaskets for Merc carb. Tell her I sent you. Im not sure what the shipping would be on the carb,but just send what ever is on the PO shipping label. I think its too high for a flat rate box will have to use a bigger box for carb.

The 2 cores you have don't have the small inlet hole you need,all other parts are useable on them. Only order 1 set if you want. (don't loose any of the smaller gaskets or you will be in a bind) no other gaskets replace those. The postage charge will be on the top right hand corner of the box,just send me that chg.I told you that in the last email read it again. ken ct.

I don't plan on rebuilding the carb myself, after taking a core apart and having never rebuilt a carb before I have decided to send it out to have it done right? So I don't see why I would need the gaskets sets?? Can you rebuild it? or do I need to send it to Daytona with the core that I buy from you? Thanks for your patience, Randy
