How to use the primer.

My boss picked up a '96 380 last fall. The first snow of the year last year and he couldn't get it started. Turns out he ended up flooding it out. Well, now a year later, he can't get it started again. This time, there is no fuel which tells me dirty carb, no problem. But, I would like to know the proper way to use the primer so he will be able to get it started everytime. Thanks for your input.

Old primers are very temperamental. Often, the first 4 or 5 pumps on an old primer is nothing but air. Then, it finally grabs fuel and will feel just a little different. He'll need to learn this feeling. It only takes 1 or 2 shots of fuel to get an easy start. However, 1 shot too many and she'll flood for sure.
So, try 2 pumps, then pull twice. If no start, 2 more pumps, 2 more pulls. Repeat as necessary until he learns the slight difference between pumping air, and pumping fuel.
This is of course on a cold engine. A well tuned warm engine needs no priming.
Good luck.

The primer will also make a different sound when it starts pumping fuel too.

the nice squishy sound is priming. another thing to keep in mind is relative temp right now mine starts on one prime but come -10 it takes 3 primes. just got to play with it and figure what she likes. id also recommend replacing the current primer. i do mine every 1-2 years for piece of mind. if it starts getting flow by you'll foul plugs and ruin your day.

Hey Duck,
Where do you get your primers? Thanks.

local dealers or any where that sells parts really. pretty common replacement anywhere should have them in stock. i prefer the parts unlimited ones they seem to last longer.
