I have a truck with a 350 chevy in it, it has a 4bbl Qjet and it's a '79 The carb has a man. choke When I start the thing it's fine, take the choke off as it warms up, driving and stoping at lights with it in gear and then going is fine. but if I stop and put it in Park or Netural, and let it idle for a few seconds, the second I step on the gas(even lightly) or put it into gear it stalls unless I pull the choke on full, this is all the time when it's cold and warm, if it's realy hot it just has to idle for a few seconds longer. Does this sound like I need to rebuild the thing or some of the adjustemnts are off or does it even sound like a carb problem? The thing that makes me thing like it it a carb problem it when it's stalling if I forget to pull the choke it makes a fairly loud sucking sound, I can just hear it over the engine with the driver window down. and I don't have to hav ethe choke on for long, just a few seconds till I get rolling or it comes out of the low idle, but it is a pain. Any ideas?

This is true if all else remains the same on the engine. Also more of the thermal energy is transfered into the exhaust and makes it hotter. This heat aids in burning off emissions in the exhaust system. And it sharply reduces the possibility of an exhaust backfire. However compensations can regain peak pressures as noted in your post below. AB> ...this is good AB> for reducing emmisions-but bad for economy, driveability and heating of AB> coolant." As for heating of coolant, or the engine in general, I have found retarded timing to reduce thermal transfer into the combustion chamber and coolant, if all other things are the same. One easy way to overheat an engine is to have too much spark lead. AB> "The use of a retarded spark requires richer jetting in the idle and AB> main systems to get off-idle performance and driveability." Only if the spark is retarded across the entire engine RPM range will the main circuit need to be richer. However the use of port vacuum only retards the timing at closed throttle settings. Open the throttle and the timing will be the same as it would be on manifold. The main can be the same. The idle will be set more open to get the proper idle rpm, and the mixture MAY need to be slightly richer, depending on other engine systems that come into play. On a stripped down hot rod engine the idle could need to be a bit richer on port vacuum, than the hobbyest found he could get by with when he had manifold hooked up. AB> "It must also be considered because high temperatures at idle due to AB> the retarded spark and high idle-speed settings definitely promote AB> dieseling or after-run." I think the "high idle temperture" stuff is bogus. However the idle rpm setting need be no different. It is just that to get it, the throttle will have to be adjusted more open relative to an engine getting manifold vacuum at idle. The wider throttle settings can cause after run. I have experienced it, especially with higher compression engines. I prefer to use a throttle stop solenoid that allows the throttle to fully shut when the ignition is turned off.

If your car is nearly stock as are your systems, then making sure everything is right and doing tuning tweeks here and there, starting with factory specs and setups as a referance point. The biggest problem I see with the engines compartments of El Leadfootos is that stuff is in a mess and not hooked up or working. Distributors are a big offender. AB> Could one not argue that under idle to just 'a little beyond closed AB> throttle' manifold vacuum gives you an advantage for a standing start? AB> (becuase you have manifold vacuum, but no ported vacuum.) AB> Granted, the time period for this is short, and mechanical advance AB> will take over. But it is a possibility. =) If throttle sharpness is a concern, the best answer is a fine tuning. After that *maybe* a notch on the accelarator pump. Lowering friction and improving operating efficiency are also good areas to work on in a nearly stock engine. Myself, I would put on a set of headers, windage tray, and an intake such as a performer. Cams that are set up for 4WD truck engines tend to deliver sharp throttle response and fairly normal drivability. Not really hot rod stuff though. If your just wanting to stand on the throttle and move out quick, a higher stall torque converter can give you an advantage if all else is the same. Lower gear ratios might be the next step. Some of those things may get you a fun street rod. --- Blue Wave/Max v2.12 [NR] * Origin: Skeeter Haven "Nashville, TN" (615) 872-8609 (1:116/17) --------------- FIDO MESSAGE AREA==> TOPIC: 155 OLD CARS Ref: E3H00000 Date: 03/12/97 From: ELVIS HARGROVE Time: 03:45am \/To: BRIAN WEBB (Read 0 times) Subj: engine prob. -> or it comes out of the low idle, but it is a pain.

Hi Craig, Not just speed parts, anything you mail order. But again, this is a number of years ago. Things may have changed since then. But I suspect it hasn't. =( > Essentially double. Is that in CDN? Still, for a matter of geography Yes, CDN dollars. And in Ontario, add 15 percent (GST and PST) Maybe I should consider starting some parking lot maintanence across the border, if we're almost double. Mobil 1 costs $5.97. Which puts my DIY oil change above letting a real mechanic do a normal oil change. > it's a rip-off. Not being an economist, I can't speak to the issue > of cross-border dollar dynamics. But it still stinks... Since I don't do much if any cross border trips, I can only relate what I gather from watching the odd RV show, Depending on how long you stay in the US, you are allowed a maximum dollar amount back into Canada. When you come back, you get taxed (duty, salestax) on what you bought. Except on a number of exempt items. If you are above that amount, you get slapped with some other form of tax. Yup. Definately stinks. BTW, you can buy our locally brewed beer cheaper than we can buy it at the brewery. > Absolutely. What I haven't been able to figure is why the 15" > are so scarce?

Pumping Same here, but the problem though is you can't measure the oil level as the suction is on the side. So I add the port at the top and slide a welding rod down as a dip stick. Needs about an inch or so of oil. The pistons are horizonal at the bottom so don't get the oil level too high. > striaght UP to a surge tank where the oil can drain back down to the > compressor don't let as much of it get lost in the output air. But how does the oil return to the tank? The reed valves in the outlet line will prevent back flow, so you'd have to add some sort of small bypass, no? What happens to all the water from compression?

Compressed air is not to be fooled with. Good friend of mine tells a story of group of engineers testing a length of new plastic gas pipe. Why the they used air is beyond me but when it blew pieces flew all over the yard. They did clear the area beforehand and were standing inside the shop observing through the window of the overhead door. A chunk lodged in the door panelling right next to them. It doesn't take a lot of volume to be terribly dangerous. --- FMail/386 1.22 * Origin: What's_the_Point? (1:140/23.10)
