What a weekend!..

Postby 89rebelpup » Tue Mar 12, 2019 8:17 pm

Hello pup and pickup friends!

Well where do I start?.. Saturday (03/09/19) at about 8am I pulled my 1989 pickup into a borrowed garage to start what was supposed to be just a valve cover gasket replacement and hooking up an fpr that in preparation for my weber 32/36 conversion. Now I had all the pieces and parts to go full carb swap but I wasn't certain I'd feel all that froggy.
Well ..it turned out I apparently felt very froggy because about 12 hours later I had the new plumbing (with gauge) and fpr installed, an hour and a half parts run later for a new mechanical fuel pump and an hour or so of wrestling with two nuts and washers through a wheel well and around an AC and power steering pump I had it installed. I had the factory carb removed, some of the various vacuum lines plugged/capped, mating surfaces cleaned and the redline weber sitting hand tightened in place but nothing yet attached or adjusted.
Sunday am, I missed my weekly worship and fellowship with my church family in the attempt to making my daily driver roadworthy again by Monday morning. I was ok with it because I know my Lord understood, loves me and forgives me for such absences (and hopefully a few cuss words in auto repair aggravation) besides I was certain that He was also with me in the garage under the hood of Blue as much as with my brothers and sisters in our church sanctuary...anyway so... whatever.

So after about 2 or 3 more hours Sunday morning I finished my redline weber install after many prayers, praising of His name, some creative throttle linkage fabrication, aforementioned cuss words (and their apologies).. I had the battery cleaned up and reinstalled, gave the fpr and fuel pump installs a quick mental inventory and then with everything hooked up and everything double checked, my extra parts and tools removed from under the hood and the truck lowered I turned the key. Once the pump, lines, inline filter and fpr primed the truck fired right up!

Before I continue.. and I will because it is not proving to be trouble free and I have questions and need help... are there any questions, comments...concerns? lol..

LoL.. well thanks for that!

So now in the aftermath of that killer weekend I'm still experiencing unfavorable operating conditions. I've learned largely in part to.. you might have guessed it.. Human error!... :oops:
More like stupidity really, so much so I hesitate to even own up to it. Partially caused by putting too much trust in the manufacturer and/or the vendor and that the product (the redline weber conversion kit k697) would be fully intact.. But that would just boil down to being an excuse really.
Let's just say such a kit can be installed and function (albeit poorly) if you install only two of three gaskets normally required. :roll:

No... though I wish it were running okay now.. waiting to hear back from partsgeek customer service, who's waiting for the manufacturer or supplier.. Saturday am I will probably disassemble, make my own carb gasket and install it then reassemble... AND I may as well do my valve cover gasket because I know it's leaking and there's no sense in trying to set the carb up with any vacuum and valve cover leaks.

Disappointed with partsgeek answer, which was disassembling everything and returning the entire incomplete kit to them... while my daily driver sat and waited for them to ship a new kit, I decided to call redline weber people directly in California.

Do you know.. after 2 weeks of waiting for the parts geeks to make a decision.. it took redline no longer than it took for me to explain receiving an incomplete kit and giving them my shipping address and contact information that they had a complete adapter and gasket kit on its way to me free of charge and It arrived 5-7 business days later!
Then the following Saturday I was back in the garage and did the valve cover/semicircle gasket replacement as well as the dismounting, cleaning, reassembling and remounting the carb kit.. only this time with the right amount of gaskets and also applying some gasket seal between each mating surface and where applicable using the right loctite this time.
That was a few weeks ago and honestly It's still not right as it hesitates when I first go to accelerate, the carb, under the closed hood driving it, seems to make alot of sucking air sound for only mediocre response or speed. I've played with the idle adjustments at different times trying different settings AND I've even installed a fairly stout return spring in the process and still idle is real rough AND it intermittently will still diesel (or runon) when I turn the truck off.
I know there is still posdibly a slight vacuum leak at the carb mounting (could be cause?) I still have a number of the various vacuum attachments and lines connected (could be cause?) ..at fueling up this afternoon I noticed there was alot of vaccum pressure at the gas cap (could be a symptom to the cause?)... frankly, I'm not sure if I'm more frustrated or the fun of the challenge has worn thin and I'm plain tired of trying to make it run right.

Any of this sound familiar or give any of you an indication of what I'm not doing right or what I need to do to get my truck running right??.. please advise!

Ok a strange thing happened last Saturday.. after all that I've done (and continue to do) sitting at a light with my truck idling like poop and BiNg!.. on comes my O2 sensor light and hasn't went out since.
Now I know after installing the Weber the O2 light as with the rest of the emissions means nothing to me except ..either the truck running rich as it is has clogged up the sensor AND/OR the sensor has finally recognized that lines have been removed and capped, that the smog pump and egr is missing and just decided to signal.
Regardless I guess removing the applicable peanut bulb behind the cluster will fix that.. I wish I had one of you experienced and knowledgeable isuzu/ engine/ weber swap/ etc.. guys living close by!

Going off of memory here, so cut me some slack. :? Gen I Troopers have an idiot light that comes on at a certain mileage as a service reminder. There's a reset button on the back side of the speedo. Maybe your truck has the same "feature"? Think I've seen this mentioned over on the Planet. Try searching there. hth.

Considering the following to correct my ongoing weber "upgrade" issues (in no particular order):

To purchase/install a new fuel filter.
To purchase/install a new distributor o-ring.
To purchase/install a smaller idle jet. (Size?)
To Measure/adjust carb float. (Setting?)
To Check (and possibly loosen) the throttle shaft nut and secondary nut as needed.
To Set/adjust engine timing in consideration of Weber recommendations. (Setting?)

Now... I've seen some or all of these tasks spoke of here on this site so I just need to recall where exactly!
Then of course I must find a "weekend" to do it all in.
