my merc dosent like the cold

[Dave84]

on my way to work this morning i was going to get a coffie from tim hortons, anyway i was comming up to a stop sing and my car just started shaking and stalled, then it wouldent start so by then i had a whole line of cars behind me so any way got out to check that my choke wasent stuck it was fine tryed to start if finaly got it going then i came up to a corner and it died as i was going around but started after a couple trys and a few miles down the road it started running perfectly, what are the things i should check to correct this before the mornings get much cooler, btw i have a manual choke...

how cold was it this moring dave? wish I could help you out I don't know much on carbs hope you get it fixed mang

[Dave84]

only about 10 degrees so i hate to see how it runs when it gets to the minuses

[gabegt90]

dam that's cold I didn't think it get that cold that eairly that also remines me I got to put that new sensor for my atc

How long had the car been running at this point? Was the choke full open or partially open? If the motor hadn't been running long, its possible that you need to run partial choke to allow it to warm up. I'd really have to suggest re-installing a normal electric choke, since those will slowly open as the engine runs. Also, leting the car warm up for several minutes before taking off would be a good idea. Having an operational heat stove is another thing you should check. The heat stove is that tin junk around the driver's side exhaust manifold. There will be an aluminum/paper tube connecting from it to the bottom of the air cleaner assembly. On top of the air cleaner is a vacuum motor that runs a flapper valve. This should be plumbed to a thermostat located in the air cleaner lid right next to the carb, and fed with engine vacuum. When cold, the flap should be closed, forcing warm air from around the exhaust to be drawn in. When the car warms up, vacuum is cut off and the flapper opens to allow cool air to be drawn in. The warm air is important to accelerate warmup and help prevent carb icing. You might also have an exhaust heat riser setup. This is normally a vacuum motor that closes off the exhaust on the driver's side, forcing exhaust to cross through the intake manifold passages to exit the other side. The effect of this is to warm up the intake. If that passage is blocked with carbon, or the heat flapper in the exhaust doesn't work, it will make the motor warm up slower too.

i normaly drive with full choke then when it starts chugging i push it half way in then onece its been driving for another 5-6 minits i fully open it. I have 2 snorkols but niether one of the aluminum tube's are connected beacause my drivers side heat sheald rotted off and the passenger side one isent there beacause i added the other snorkal, mabie i can fab somthing up on the weekend since ill be changing my timing chain and front oil seal,
