Warm Restart

Charles · Post by **Charles** » Tue May 02, 2006 11:13 pm

Hi Guys,
Now that its warming up here, I'm getting the infamous "warm restart" issue after the K sits for a short while.
No big deal (1/2 to full throttle start works), but I wonder if anyone ever got around to posting a "fix" or a "why does this happen" post for this before the board crashed.

Also, might be a nice repost for the really really new folks who have joined post-crash (I'm just about to new-ish, not really really new).

Thanks!

I've noticed that every Pinzie seems to have an easier time starting when cold. You're right, 1/2 to full throttle (no pumping) is the trick to get it to cough to life sometimes. I'm used to it now, but at first I was nervous that it might leave me stranded in the middle of nowhere, so I would only shut it off if I was facing downhill so I could possibly jump start it! Now I know that it's just "the nature of the beast" and give it some generous "right foot" when starting.

Boy these little trucks can be tempermental!

Are you using the choke? I find the key to an easier start - hot or cold - is proper choke adjustment. In my case all the way on for cold... half way for hot. YMMV

After recently retightening my carb bodies this problem has pretty much gone away.

On occasion thou I still have to hold the pedal down to get it fired again. This may have been due to running it up in the mountains 10,000 ft being a little richer?

isn't the hot start prob due to the float fuel boiling off?

Yeah, I dunno guys. However, I'll try the 1/2 choke thing...
It's not a huge deal, just a little "embarrassing". I go to these events, shut down the Pinzie for a little bit, then I inevitably get asked for a ride or something. I have to then 1/2 throttle and crank 'er a bit. Sometimes I get a little puff of black smoke from over-doing it. Makes the Pinz look like a POS, even though it is a great vehicle...

Just wondering if anybody has really pinned down the cause. I've heard the float-fuel boiling off as well. Have not been able to verify this.

Seeya!

Hi Guys,
Same topic, but worse....
I was at a Military Vehicle Show this weekend. Long story short, after a short drive to a gas station to fill up on the way home and a short sit time (10 minutes) I had a massive problem trying to restart warm.

Basically, I had to crank on the starter 3 times for 3 -5 seconds before it finally fired up (no choke, 1/2 to full pedal no pumping). Didn't catch, didn't catch, them finally "swoom" started like there was no issue. No black smoke puff or anything at that point (which would indicate some flooding due to my idiotic cranking). Just seems/feels like there's no fuel in the carbs...

So, I'll check the floats again, but I wonder if I have a problem with my needle valve not seating properly? Could these symptoms be explained by that? Since we've got dual carbs, would BOTH needle valves need to be seating improperly to cause this? How would I check this condition?

Any tips from the "old guys" (

) would be much appreciated

FWIW I never touch the gas pedal when starting. I find that when the choke is set right - no pedal needed [in fact it usually hurts more than it helps].

One overlooked item is the wire from the distributor to the coil(-), if the terminal end corrodes you will get a loss of spark. I have fixed a few hard/no starts by cleaning the contacts

Get a float level guage to check the carbs, check the shutoff solonoids, then make sure you have a good spark.
Also remember unlike fuel injection, you must prime(depress the gas pedal at least once) to start a vehicle equiped with carbs.

Bad points or a failing condenser can also be a factor.

Hey Jim and guys,
Thanks for the reply.

I'll take a look for my spark quality/clean some contacts.
Have a float gauge (good last time I checked), did a "click-test" of the solenoids not long ago, but will try 'er again.

No more points (electronic ignition)...

One thing to note while inspecting the solenoids:

I had one that passed the initial test disconnecting & reconnecting listening for the "click". Then I noticed while reconnecting that the spade connector on the solenoid was somewhat loose in that I could push it in & out which caused the unit to turn off & on. That little devil drove me nuts for about a year until that day noticing the short. Promptly ordered a replacement & it was noticeable in many ways as I couldn't accurately balance the carbs, it tended to run rich before. Now for the most part it starts easier initially, idles smoother & restarts after being warmed up

i've noticed the electrical connectors on pinz's are very crappy. this seems wrong, noting that it is supposed to be submersible, able to withstand abuse, etc. now i'm not talking about the affects of age on copper and brass, even. seems like they cut some big corners in this area for some unknown reason.

In my experience, Warm restart issues in a Pinz = Carb fuel level too high!

Check fuel level with tool and adj. as required.

Make sure truck will run at highway speeds for 10 minutes constant after adjusting fuel bowl level.
