Revs 71

ooooh I gotcha, I thought you meant you checked the valves and that was the culprit

Running but not really

Per Duane....I checked the valves and they were all at a snug .006.   I checked the points again and set them to .016.  I static timed to 10 btdc  and started er up...the car is still popping and sputtering...from both sides....what I noticed today because I have the preheat tubes unblocked right now is that when I look in them and rev the engine I can see flame.....sooo...I am wondering if anyone has any other ideas for me....I am probably missing something simple but I cant for the life of me figure this out.  the car idled a little bit today but it was because the throttle didnt return fully I think.

The other thing that concerns me, and Im not sure its in the video...is this engine shakes like mad when its trying to idle...Im so far removed now from having a car that runs normal that I cant remember how much shake is "normal" when these things are sputtering a little.

Anyway...Thanks for any input.

Did you sync the carbs?

Are the plug wires connected to the right plugs?

[Revs71]

I have checked and rechecked the plug wires so I am 99.9 percent sure they are correct....I followed the procedure for syncing the carbs on the low bugget site to the best of my dual carb noob ability.  So i just dont know what gives....Im gonna try and cajole Kev over so I can get another set of eyes on the thing just to double check my work.

[CatBox]

It is known that the Kduds will idle funny so not to worry.
Lots of info on the samba about 2 cylinder idle issues. 
Mine didn't do it though.

Are you running the balance tube thingy?

My engine would shimmy and shake, but I needed new motor mounts.
After I put new ones in it still did the wiggly dance just more like an uncomfortable man dancing and less pro break dancer.

You no longer need the preheat tube dealies and there are block off plates at DIP that bolt on to those risers to stop the extraneous flame propagation.

[BuginU2]

Yeah - what Peter said.... you do not need the pre-heat risers anymore.  Get a block-off from DIP to cap them off.

If your kadron manifolds have the tubes for the cross-over hose to attach to - either put the cross-over tube on OR cap the tubes.  The tubes are typically on the back (firewall) side of the manifold.  The tube size is about 3/8 inch or so.  Normally you'd connect the two manifolds together to balance the engine out some.  You might want to run it. 

You going to be around your house today?  I might be able to drop by around lunch time.

install the cross over tube. kdogs need them

[Revs71]

Im home all day today unless the Ford dealership calls to tell me my explorer is ready....

The crossover tube is connected although the hose is a little long if it matters.  I plan to block the heat riser tubes today as well if I can find my block off plates.  I just never noticed fire that shooting out of the exhaust site of the heads before (it doesnt come out of the heat riser openings I can just see if when I look down them.

I am going to check on the new mounts I put in under the bell housing today too...just to make sure the thing is sitting tight.

The Good:

• Kev lent me a sychronizer so I can do it right
• My car idled on its own for about 4 minutes today...it hasnt done that for a long time...it stopped when I cut the power[/li
  
  • Car was running much smoother today...Static timed to 8 btdc and set both carbs idle jet out 2.5 turns (they were at 2 before)
  
  The Bad:
  
  
  • Remembering I knew my problem would be something "simple"...I noticed today it was loping on the idle which led me to check for vacuum leaks....guess what I found where the manifold meets the head 
  
  Next step is to get a new gasket and to retorque the intake on that side then to sync the carbs and see where we are

Make sure the base of the manifold that mates with the head is flat. Some heavy-handed DPO may have warped it when he or she torqued the nuts too much.

If it isn't flat, it can be "home milled" flat. Use a piece of abrasive paper on a very-flat surface. Piece of glass works well. I use a large, marble tile from Ho' Depot.[/list]

Just a little update...



I fixed the intake....Took it off, painted it, reinstalled after replacing the stud in the head that just wasnt quite right.There is a noticeable different in smoothness of idle and willingness to rev without sever popping....still some backfiring out of the carb but I think its because I need to get both the timing on the 009 set up right and I put a sync tool on the carbs tonight to see how close they were and 3/4 is at about 6 where 1/2 is about at 4...Im gonna read up on adjusting that tonight and get er done tomorrow. 

[Revs71]

Took off the 1/2 side carb and intake to fix a stud that was keeping the intake from sealing all the way...much much better now.  Everything is all back together now and the block off plates are installed.  I noticed a big drop in idle already which is good.





Also had to modify the little stabalizing lever for the linkage.  I was noticing a little "wiggle" so I wanted to secure it.  Works great with no hangups.


I also got the block off plates put on the heat risers so no more exhaust leak.  Car is idling well.   I still need to time it correctly and adjust the carbs properly but it's too late tonight. 

[Revs71]

The big news is...I'm ready to drive this thing to the next volkster event I can make...what's coming up that's not on a Tuesday night?   

[CatBox]

The doughnut thing is on one of the Saturdays.

Good to see you have your car sorted out.
