 I have been mostly running my other boat. I got the 85 2001 out this weekend to get it prepped and ready for our upcoming adaptive ski clinic. She was a little hesitant to fire up, letting me know she is disappointed in how much I have been running her. However, she fired up to life and purred! After she fired up I did notice some gas pooling on the manifold, where the red arrows are in the pic. I did notice a drip from where the green arrow is. Should I just plan on a full rebuild? The prior owner sent the carb off years ago for a rebuild. It is probably due. Or is this a sign of something I should try to address sooner? I have rebuilt a mercab before, just not a holley 4 barrel. I am game to give a try, though. Thanks, Richard ------------- Hotty Toddy lets go skiing! |

The green arrow is pointing to a plug just like the 2 on top of the bowls that you or the previous owner epoxied at some time. Dig out the epoxy and do the same to that plug and the corresponding one on the front bowl as a start. It's hard to tell from the picture if it's been done already There's an o ring under that plug that gets old and leaks It looks kinda like an oily residue in the picture The thread in the link below has a picture of the plug and o ring http://www.correctcraftfan.com/forum/forum_posts.asp?TID=41088&title=carb" rel="nofollow - link |

It is clear gas. My engine had needed a good cleaning since I got the boat. That area seemed epoxied to me so that totally makes sense. Thanks for the link. Would you not run the boat with such a leak? ------------- Hotty Toddy lets go skiing! |

I'd roughen up the area, clean it good and epoxy it again and see what happens as far as leakage. I doubt that anybody will jump up as say to use it as is with the leakage 'cause they'd feel bad if it got suddenly worse and you had a fire/explosion. |

Do the local auto parts stores (Napa, Advanced) typically have the o rings for the fuel bowl transfer tube, and gaskets for the fuel bowls? ------------- Hotty Toddy lets go skiing! |

Here is a close up on where the fuel bowl transfer tube goes in. This looks epoxied too. From my records I am pretty sure this is an old National carb rebuild, from years ago. Should the be epoxied too, or should I go with a new fuel bowl transfer tube and new o rings? .  ------------- Hotty Toddy lets go skiing! |

If that really is epoxy where the transfer tube goes into the bowl, you may have a helluva time trying to get all the epoxy out and having a smooth surface for getting a seal with new seals. Let's hope it's dried up grease that somebody used to slide the tube and O ring into place It could be new bowl time If you're replacing things go with a Holley 26-115 transfer tube kit. The new style seals are easier to use and a lot harder to screw up and cause a leak You'll see pictures in the link below. Ignore any of Pete's backyard, shade tree hackery in the link  That link also has a link to the 26-115 transfer tube kit at Jeg's, but there are plenty of places to get it from. http://www.correctcraftfan.com/forum/forum_posts.asp?TID=41205&title=another-4160-issue" rel="nofollow - link |

I did the all mighty screw up (tore) of the transfer tube rubber seal on my Quick Fuel 600 . Am I understanding correctly that you can use epoxy as opposed to a seal . And if yes , what epoxy is recommended ? If no, does anybody have the part number for the seals and I guess a new tube would come with the kit ? ------------- Feels like I am hanging 10 but in reality - probably hanging 6. |

You can use epoxy................if ya' really wanna screw things up So no just get new seals, don't even think about epoxy. Holley seals work. Do you have o rings or the newer sleeve type seals ? |
