A what the heck, no start

85' GS 12a, totally stock. 55,000.

The car has never had starting issues. Parked it a night ago after driving it until it was fully warmed-up. Went to start it the next day. Car cranks but doesn't even try to stumble. Did a quick check of spark, shocked myself. Had my friend pumped the accelerator while I checked the carb, fuel squeezed out. Tach does bounce when crankings, healty crank.

It is cold, I know people have flooding issues. I've never had them. This is my only transport right now, I need it. And basically I have to get this car back running by thursday night.

All ideas and feed back welcomed. Danke.

Sounds like its flooded if you have been pumping the gas.

What do the plugs look like?
If they are wet...Try taking out the leading plugs clean them and turn the engine over by hand a couple of times. Then hook everything back up and it it should start (usally works for me). After you may need to start turing the enigne over (with key) and just press the gas down for a couple of secs. If not you may need to dump a cap of seafoam down the carb.

I haven’t had an opportunity to pull the plugs out. It is stranded at my friends house right now, and my tools are elsewhere and can't reach them without my car. Viscous cycle. Though my only instinct is that its possibly flooded. Pouring over archieved info right now.

I'm going to get it towed to a garage I used to work at. But wanted a plan of attack prior to it. Thanks for response.

Just grab a can of Seafoam, and pour about an ounce down the primary (smaller) barrels of the carb. Crank her over and she should start right up (ignore the white fog of smoke). Works great every time.

Spark...fuel...should start. One very shade tree way to get it unflooded would be to take a pair of vice-grips and crimp off the fuel going in and spin it over....

Do you have the thump thump? Has it washed the seals out? Sea-foam has a spray ... That has always worked with me.

One last thing --- Don't clean the plugs --- get new ones... After you sea-foam and flooding - those plugs are not going to be happy... get it started...warm it up and change the plugs after sea-foam and everything -

Good luck -

Crimp the fuel line? I would not advise that. There has to be another way without risking cracks and what not. I am allergic to engine fires.

if none of the above info works try looking for a vacuum leak. i was driving back home one day and all of a sudden my car stumbled and died. turned out to be an internal vacuum leakage in the air control valve good luck

I always carry a spare set of plugs in the bin along with a 13/16" socket and ratchet because that usually will fix it. Sometimes those plugs are not new but just cleaned up old plugs, and that works too. In very cold climates like PA it might be good to have some starting fluid or ether in the bin.

When you get the car running put a timing light on it and check the timing.
