Best set up to get engine to start......

When I start my engine cold it starts with a reasonable amount of cranking. After the engine is at temp and I try to start after 30 or more minutes it is difficult to get started. It turns over without any problem it just take a while to start and then it runs fine. I have a hei set up 10*advanced initial. Carb is set up a little lean. Any suggestions?

Re: Best set up to get engine to start......

When car is cold, step on the pedal a couple of times. This causes the choke plate to close and an extra gas shot. Engines need extra fuel to start when cold.

When engine is hot, the fuel has probably evaporated from the carb, regardless what brand you have. The reason for the long crank is the mechanical fuel has to fill the fuel bowl back up. Then fuel can be pulled into the intake. You might even try a 1/2 pedal stroke to fuel some from the accelerator pump.

You might even try a different brand of gas. If not your daily driver, it may have a winter blend/recipe.

Weak spark will effect cold or warm starting. Could be coil, plug wires, plugs and plug gap, cap or rotor. Lack of fuel as already suggested will also cause starting problem. Check your squirters, watch them and move the throttle. If they squirt you have fuel in the bowl(s) and I would say fuel isn't the problem. Make this check before starting the initial time and do it again when hot to proove it out under both conditions.

Also as already suggested, we are use to not touching the gas on our modern computer controled fuel injected cars when starting them. Old cars need a 2 pump in the morning, if they have a choke this sets it and gives a squirt of fuel too. When warm my cars don't need the extra pumps but I have seen many that still need a pump or two... The caution here is learn when you have flooded the engine as then you need to put the pedal on the floorboard until it starts..

Re: Best set up to get engine to start......

Sounds like your carb float level may be too high. You may want to check it.

Re: Best set up to get engine to start......

Carb is a Q-jet. I think I may need some practice at finding the right "touch" to start get it started quickly.

Re: Best set up to get engine to start......

Here's my suggestion; but only if you have electric choke........

I had this problem on a couple of different cars. One had Holley carb and the other one was a Q-Jet; both carbs had electric chokes. Finally I figured it out. The electric choke spring cools down much quicker than the engine. So, the engine gets up to running temp, then you park for a few minutes and when you come out, the engine is still hot, however, the choke will activate.

Now let's say you want to start this hot engine, that's been sitting for, say, 10 or 20 minutes. When you go to start the electric choke comes on (even though no choke is needed), causing over-rich starting condition and hard starting.

So, I ended up leaning the chokes out quite a bit and that solved my problems.............

No you don't need "the right touch"... You need a tune-up...

Re: Best set up to get engine to start......

DJD,
I have less than 500 mi on the current plugs, wires, dist, carb, etc. Carb is new and dist is hei. What would you suggest I change? I have found that it starts quicker when I depress the pedal about 1/2 way down when cranking.
Chevy-SS,
The carb does have an electric choke. I have noticed that when It has trouble starting the idle is low initially and then will smooth out after revving the engine.
