Makes sense as liquid distribution systems in industry typically have a check valve down stream of the pump to ensure the pump always has some pressure.
Thank you that makes ton of sense. I don't remember as kid in the 70s my parents having to crank our cars as much even in the winter. Granted the cars were technically newer back then but still.
I think I know why RPMs are sticking high after starting. My throttle return springs are losing tension and it is just keeping the throttle open more than it needs and not retracting back. I bent the springs just to see if it helped and it did. Ordered new ones though . Wow may have fixed...
Holy Toledo, after lubricating the choke linkages and let sit for an hour, heard ignition on the second turn and it started on the 3 crank in February!!!! Wow I can't believe it. Normally I'm struggling in the winter.
I noticed my air cleaner is really dirty too. Thanks guys!!! I...
Thank you very much - makes sense. By the way, to clarify, I understand that the check valve will not prevent the carb bowls from going dry. What the Youtube video meant is that a check valve would help you start your car with less cranks if your fuel fully drains back to your fuel tank and...
I have conflicting info on this. Some say the fuel pump has a check valve and some say it drains back to the tank. Are you sure it drains to the tank? My apologies just want to double check.
FYI, I only use ethanol-free gas. I read that the fuel pump is supposed to have a its own check valve so not sure if it goes back to the tank or just the fuel pump.
The car original had a 318, it was replaced with a 72 440. The carb is a Carter 4 bbl. Not sure if that helps with the...
Hi good question and no, no entirely sure. I just went and opened up the air cleaner and the choke was closed and then I gently opened it and then it retracted. It was a tiny bit sticky to close so I sprayed some Corrosion X on the linkages and it retracted a little better but that doesn't...
Hi gents, been awhile. Car needs excessive starting turns when sitting for more than a couple of days especially in the winter months. It's been cold this year too. Summer not as bad where it may be affected after sitting more than a week or two. I saw this Youtube video where someone...
I hear yah Mike. Thanks. But I just went to the car in Park cold just now (I started it and ran it yesterday), pulled the NSS connection to the starter relay, put a test light and it is grounded. Just now, I went to start the car cold and in Park and when I went to crank it, it cranked the...
Hey Kern, I would not rule out. It could be the shifter linkage adjustment This symptom did it before the new NSS and it does it after the new NSS and the previous mechanic did adjust the shifter leakage and he also replace the leaking seal. I know the mechanic had some issues with this so...
I was thinking the starter or startey relay and I eventually may just change it as not expensive. What boggles my mind is that when I switch the car into neutral the car will turn over as many times that I want - if it was the starter, it would have the same symptom regardless of the gear...
Purepony, just out of curoisity for understanding of the problem that you had, your car ran great otherwise after starting, but did not crank at all when cold or for awhile and adjusting your timing fixed that? I take it adjusted your timing did not negatively impact it after it did start...
Thanks, don't think it is a timing problem. If it was just the timing the car would crank but would not run or run poorly - that isn't this case here. I think it is some type of electrical problem where the engine is not cranking at all under certain conditions mostly in Park after not...
