Hey Hey Hey...

14 days later and progress has been made. Just when I thought my troubles were solved they were not. After my last update I ordered the new gaskets, pulled the carb, tightened down the manifold again, and put it all back together. Once all that was done I was still having idling and running issues. Once everything was warmed up it would not idle at a low RPM, ran rough, would die after about 30 seconds if you did not bump the throttle. It did however die now when I put my hand over the carb. The vac reading hovered around 9 and the idle speed was surging. All the symptoms of a vac leak...

I have been really busy these last two weeks and have only had a hour here and a hour there to tinker with it. I first tried to listen for a vac leak with a stethoscope which yielded nothing. Used propane and still nothing. I then tried to do a shade tree smoke test. Connected a rubber hose to metal nipple that the PVC connects. Blew a whole bunch of cigarette smoke in to the engine through the tube and had a buddy put his finger over the dipstick tub hole and the oil fill tube and then blow in to the tube to put it under pressure. Could not hear any manifold leaks with the stethoscope and did not see any smoke leaking out. Based on that I decided that there was not a manifold leak. Attacked the manifold vac system next. Basically the same thing. Plugged all the manifold vac sources. Put a tube on one nipple, rubber glove over the top of the carb, and filled it up with smoke. Again no leaks that I could hear with a stethoscope.

Today was the break through day. Pulled the carb again and installed the 1.08 2100 that was on my 258. It has a bad accelerator pump and developed a nice little spiders web inside. Before I installed it i turned the screews 2 turns out. Hooked it up using the gaskets that were in place from the 2150, a little gas down the carb, and she now idles like a champ. Idel speed does not surge and I am getting around 16 on my vac with no tuning and no pipes past the headers.

Who would have thought that my rebuilt carb from National would have been the problem...

Before I pulled the 2150 I disconnected the fuel line and ran all the gas out of it. I also noticed that when I pulled the 2150 the gasket was wetter than I would expect with gas.



I am out of time with it till Friday, which I took off as a jeep working day. So the plan is Friday AM, after dropping the kiddos off at school, going to trailer it to the exhaust place to get some pipes and mufflers and then figure out the 2150 problem.

So close....

Hey Moc,

Exhaust day is an exciting one.

Regarding your carb problems. I recall reading there may be differences in the bases of the 2100 and 2150. I'll bet the 2150 requires a different adapter plate, or gasket, than the 2100.

Like you, I'd be very surprised if there's a problem with the National carb.

Have fun, today....

Matt

You are correct Matt, the gaskets are different. The gaskets I bought are specific to a 2150.

I am pretty stumped on the carb. Torn in to it yesterday and everything looks great. Everything is clean, check ball it their, no debris under the needle, float does not appear to be hanging, power valve is not bad from my one backfire when I was 180 out. I talked on and off with National as well hunting for ideas. I did notice the clip that holds the needle to the float was missing. Thinking I had found my smoking gun I called National and the said they intentionally leave it off on thier rebuild as one of the "Tweeks" they do.

My plans are to blow everything out with carb cleaner, replace the power valve (even though I am 100% sure its good), install the missing clip they left off, dry check the float level, then button her back up and see what happens. If it is still not running I am going to pull the top and see where I am at with fuel in the bowl.

Its 100% the carb since I idles great with this 2100. National assures me that it was ran on a test engine and was functional but will take it back and check it again.

Time will tell. I had to leave the jeep at the muffler place. I sat around a little over 2 hours before the got it on the rack then they ran out of the correct size pipe and had to go get more. I was going to stay the whole time and supervise but I think the guy doing it knows exactly what I want. When I left he has the skid cut and the pipes running from the collectors back to where the mufflers will go.

So I am off to pick up Gabby, drop her off at dance, pick up Liam, go back and get Gabby, run home and get the trailer, then make it back to the muffler shop with the kids to load up before they close at 6.

Already checked that. Ran a straight edge across it and looks good. Also did not hear any air leaks when I checked with the stethoscope. Listened with the engine running and with it off when we tried to pressurize the top end.

Done deal. $649 out the door with a warranty from Meineke. Over all I am very happy with the work. I went with a set of Super V's, imitation Flowmasters. The skid plate cuts were not to bad, I just have to pretty them up a bit. I had them hang the pipes out a little long at the rear so I could decided where to chop them. The only little concern is they come out a little closer to the rear tires than I would have liked. It is really tight. He did say that any modifications / changes I wanted he could do under the warranty anytime. Going to ponder on it and see.





















Anyone have any constructive criticism?

Here she is running. Keep in mind I have the leaking 2100 on it. The 2100 that all I did to was turn the screews out 2 turns and bolt it on. No tunning. The dirty old leaking 2100 that runs... Not the pretty professionaly rebuilt 2150 that does not yet run.

The cuts look real close to the pipe, might keep a eye out for rubbing. Need shorter bolts on the flanges, maybe stainless.

Sounds real good even with the crap carb.

I was planning on shortening those bolts and also cutting some length off the ends of the hangers and painting them up.

The sound is a tad bit louder than I was going for, but not complaining at all.

Right side parking brake cable and hose look pretty close. Maybe not

Edit: Upon further review the hose I was referring to looks to be the axle vent hose.

good eye! I changed out the e brake during the 360 swap and have not tightened it back up yet. That is on the short list.

Sounds great, very similar to my Flowmaster 40's.

I was also going to mention that the passenger's side parking brake cable would get melted the first time that side of the axle drops.
