Dear all, I have a correct craft ski naitique from 1990 pn whish I just complete a carb rebuild. What is happening to me after this is that motor is hard to start from firts time. I bet the feeling that too much fuel goes in the carb and starting gets hard. After manu try without placing any gaz, motor finally start, but caughting for a whilzna finaly get lauched. When motor get a bit warmer,the no problem to start. I have notice that during cold start, the electrical choke position is completely closed and when motor warmup, start to open. Any idea why I get dificulties to start my motor when cold ? Could it be the choke position to be a little bit open ? thanks for help Regards |

Yes, adjust the choke plate so there's 1/8" opening when cold. Give it a try and get back to us. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| If it only does it when cold or after setting for a period of time it may be siphoning the gas back to the tank. I would suggest a small inline clear ( Viewable) fuel filter on the fuel line just before the carb. This way you can keep the engine box up and see how long it takes for the fuel to get up to the carb. I have seen the carbs leak gas while setting into the engine and the bowls be about empty and then the fuel line has to prime back up as well. You can also take a small squirt ( Being very sake of course ) of gas into the carb upon ignition to see if it trys to crank faster. If so its not getting fuel to the engine fast enough upon dry starts. |

I concur with Pete, choke is preloaded too much. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

Randy, If the clear filter is the common one found at many marine supplies that comes with different size hose barbs, you are recommending a potential BOMB!!! Read the specs and I feel you will find it's for outboards for suction service only and not designed for pressure service between a fuel pump and carb. I HIGHLY recommend you do some searching on the USCG regs. They are VERY specific. There are several older threads on these clear filters. Hopefully you don't have one and hopefully you haven't used hose and the plastic hose barbs. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| NO its a Glass Performance filter element for Performance applications and I stated ( you can keep the engine box up and see how long it takes for the fuel to get up to the carb) You don't have to leave it on. Don't you always say investigate the problem before you swap parts? All my fuel line is stainless Braided Hose. and all AN fittings. I have no hose clamps on a fuel system from the pump to the carb. |

The hose isn't USCG approved. Is there an approval on the filter? How about a link? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Steve, First, start cold without turning on the ignition. Loosen the round choke bimetalic spring housing. Adjust the housing so the choke butterfly is slightly open. Some find it handy to use a 1/8" drill bit as a guide between the butterfly and the carb throat. Tighten the spring housing. Don't drop the bit down the carb!  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Ok, I attempted to adjust the black plastic choke housing. Moved it left a few clicks, but the choke opening doesn't appear more open. I am probably not understanding something correctly? |

Pull the cover off and take a look inside to make sure the coil is seated. Does it open with power applied? Check to see you are getting power to it with the ignition powered up. Ohm out the coil to make sure it's not a open (no resistance). If it is, you will need a new bimetallic coil. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Hi Steve Pete explained up a few posts how to adjust it, he just didn't say which way to turn the cap. You only have 2 choices and you picked the wrong direction to turn the cap if you're trying to open the butterfly some. It seems logical to turn it left or CCW to open it, but you need to turn it to the right or CW to open the butterfly . It's a funky set of linkages in the housing. KenO |

Thank you guys. It is a new carb I bought from the boatDr about 2 years ago. I am hoping to get my boat just a bit less cold blooded. I only am around the boat on the weekend so it will be next weekend until I can get to it and utilize your knowledge. |

Steve, Fords are known to be cold blooded!  My 302 takes about 3 pumps of the helm accelerator and then generous throttle while it warms up and that takes several minutes. What happened to the old carb? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| Pete, Jeff Connors took to old carb, as it was not functioning well. I believe he fixed it up and recycled it into one of his projects, or parts warehouse. Jeff has a lot of CC's. |
