| HELP!!! I have a 1959 Rambler Super with a six cylinder engine and automatic transmission. I runs and idles fine but when I put it into drive or reverse it stalls out. The revs seem to be high enough when I try to engage the trans. What is going on? Thanks for any suggestions. |

Look down the throat of the carb and see if gas is spilling over from excessively high float (video with sound can work if you can’t tell) aside from that the valves may be too tight or a vacuum leak. Have you tried pulling the driveshaft and sticking it in gear? If it still stalls, then a transmission problem is suggested likely. ------------- Got an Eagle? http://forums.amceaglesden.com" rel="nofollow - http://forums.amceaglesden.com |

| You may want to adjust the modulator on the trans. Mine did that and a turn or 2 corrected it. |

I recommend you check your timing and the idle mixture both hot and cold. In other words, make sure the choke plate is adjusted properly at the cold setting and then with the engine warms up fully, make sure the choke plate is vertical or nearly so. Check your base timing with the engine at normal hot idle about 600 rpm or so and the distributor vacuum hose disconnected at the distributor and plugged. When that is done, make sure the idle mixture is properly set. Also, check for vacuum leaks. Low power and poor response to throttle advance are classic signs of a lean mixture or improper timing. The service manual has all the proper instructions for setting the mixture and timing. Joe ------------- Happiness is making something out of nothing. |

that's not a lot of information; but unless something unmentioned that is truly odd is going on, generally that sounds like a top to bottom tuneup is needed. carburetor and ignition work together (or fight each other, lol) especially at idle/low speeds. ------------- 1960 Rambler Super two-door wagon, OHV auto 1961 Roadster American, 195.6 OHV, T5 http://www.ramblerLore.com |

You may need to change the timing from the factory setting due to the difference in gasoline between then and now. Start at factory as a baseline. I always set "by ear". That means you find a big hill you can accelerate up in high gear. Assuming the car is running ok, bump the timing up a bit and run up the hill. Listen for a spark knock. If it doesn't, go back down and bump it up a little more and try again. Repeat until you DO get a spark knock, then bump timing down a little and repeat until the knock is gone. You may have to bump it down a little more later in the season as the temps go up and it's a bit cool now, but easy enough to do. After warm weather hits and you bump it down again (if you have to.. maybe not), you might want to get a timing light out and see where you're at and record that for future reference. You might find that you need to make a mark on the balancer, as most engines can use a good bit more timing on today's gas. Or just go through the whole procedure again... ------------- Frank Swygert |
