Location: Lavallette, NJ 08735 | Hi all, been awhile since I actually had the time to put into the old girl. I bought it with an upgraded edlebrock 4200 series carb, and it ran decent. Fuel pump was leaking, and replaced with whatever auto parts store gave me. Since then it starts strong, then just dies out, and will not restart (until the next time I try 2 weeks later). Now I had a helper scope it out back there while attempting to start, and fuel shoots out the top of the carb. Looked it up, and seems that carb will do that under too much pressure situation. Is it possible that there would be a fuel pressure regulator thingamajigl or any suggestions on reducing pressure (as economically and effectively as possible). Would I be able to get a fuel pump that simply pumps at a reduced pressure? Sorry, just not a gear head, but try what I can. Thanks, Robert
...then, I'll actually get to those brakes I asked about like 8 months ago...I hope...

In this picture of my #667 you'll notice that there is an access over the engine. I don't know if this panel exists in all years/models but you could take a look.

Location: Lavallette, NJ 08735 | Thank you, Karl, but I cannot seem to open picture. If you can describe it maybe? Mean time, now that I know there may be something to look for, I'll go do that... |

Location: Cottage Grove, OR | <p><font size="3">None of the coaches had an interior access panel from above as built by FMC. However, a number of owners over time added an access panel to their coaches. This was particularly true of the earliest coaches as the top of the engine compartment is lower for those coaches than later ones. </font></p><p><font size="3">As a result, yours may or may not have an access panel.</font></p> |

Location: Lavallette, NJ 08735 | Ok, thanks much; I'll check into it. I gotta do something, as it is nearly impossible for me to get in there and see anything, let alone work on it. I don't see anything there, so I'll probably have to open her up... Makes me wonder how they work on them at all. Maybe remove the carb, repair, and re-install? Thanks,
Robert |

Location: Cottage Grove, OR | Maybe remove the carb, repair, and re-install? Thanks, Robert This is the normal procedure to work on a carb. Also be sure to verify the soundness of the fuel line coming to the carb from the fuel pump. |

Location: Lavallette, NJ 08735 | Yes, GUILTY! My projects have a way of lingering in limbo from time to time. Anyway the access panel, itself, went well; just don't cut through your wires mounted directly below to firewall... But, unfortunately, either I spoke too soon, or simply didn't wait long enough for things to go wrong; again. The good news: she went about 70 miles under her own power yesterday (after almost 2 years idle)! The bad news: she ain't goin' nowhere at the moment... |
