Soon enough though eh? Howz the new shop comin along? I wanna stop by and say hello sometime. Oh! and show you my new exhaust! Got it welded up yesterday. Header back 1 3/4" mandrel bent system with a universal N/A Apexi N1 Muffler. Sounds cool! I'll post some pics tonight.

Good to hear, you got it running prpoerly No the sammy has a injected 1.6. but with 8" of lift and 31" tires and the worst part... stock gearing it eats fuel ( I have the 5:13 gear set to go in, but no time to do it )

Awesome guys...you've given me just enough courage to keep em on there. Actually Kurt, I did do the balancing technique you suggested before. I set the idle waaaay low right before stalling, then I played with the balancer screw. Turned it until the car revved up...backed it off until the idle went back down then kept going till it revved up again the other way, then went back t the perfect medium. That would mean they're balanced then? Well not perfectly I guess but it should work? Thanks for the email, I'm gonna get a proper tuning manual, jetting kit for my application, balancer tool, and mabe a rebuild kit for the future.

190-220km on the sammy Justin?! is it carburated? Mabe would MSD ignition control help out alittle? I'm thikin about it. MSD Digital SCI plus, $300US off ebay and it comes with a rev limiter.

ahhh...stress relieved....thanks guys!

Cheers,
Colin

Ya, I think I get about 350km to a tank with mine.

300km is good! I get 190-220 in my Sammy on a full tank

The "idle screw for sync." is on the linkage btw the two carbs. This is what you must set to syncronize the two carbs.

Colin,

If they haven't been syncronized, its a good chance thats your problem.

When I first installed my Dellortos I had some trouble with them as well. I took the car in for an alignment and asked the mechanic to play with them as they were running really lean. The mechanic played with the mixture screws but could not get it too run right. He actually thought one of the carbs was screwed. He showed me that by playing with the mixture screws on one of the carbs you could get the engine to race or stall the motor completely but when playing with the other carb's mixture screws nothing would change. I listened to him and removed the one carb completely cleaned it and even through in one of the rebuild kits but still the same thing. At one point I even swapped the carbs around from one side to the other and found that the same cylenders were having problems (3 and 4 on my EL). Now this made no sense as the mechanic checked for vaccuum leaks and the compression was up and even on all cylenders.

He admitted having little to no experience with dual carb set ups and this was part of the problem. After I kept tackling all the big things first I finally went back to the basics and spent the time syncronizing the two. What it does is set the carbs so that they are always drawing the same amount of fuel and air at the same time. If they don't they will never work right.

Now doing this depends on your linkage set up. However, syncronizing them is performed just by adjusting the idle screw attached to each carb. First set your 4 mixture screws to about 1.5 turns out. Then set the idle screw on the primary carb (the one that you throttle cable connects to) so the car is idling where you want it. Then adjust the idle screw running the second carb so that carb is drawing the same as the first one. This is where the syncronizing tool I showed you comes in handy, as it is supposed to measure the air flow between each carb. With some practice you can tell when they are in sync just by the way it idles and sounds. Once the carbs are in sync you can set the mixture screws. Turn them a 0.5 turn out...if rpm goes up then lower the idle again,,,and so forth until unscrewing them so the rpm goes down or stays the same. Mine are at about 4 turns out. As soon as mine were in sync the mixture screws actually worked!

I will try and attach a pic to show you what I mean about the idle screws.

Let me know if that helps as I suspect thats the problem you are having. Too bad, we could have syncronized them when you came to Hope

OI guys,

Alright, Well you know how on my EN1, Numbers 1 and 2 cylinder had about 50psi less pressure than 3 and 4. Mechanics at my work say it should still run with that much loss. Well now I have my dual carbs on my 1200 daily driver. I get about 300km at the most on a tank of gas. And just found out today that numbers 1 and 2 cylinders aren't firing! They did with the stock carb on there.

So whats goin on? Brand new DHLB's and one of them is crap! Argh.

Doin the head gasket on the 1200 tomorrow, gonna be taking the head off of the EN1 and putting it on the EB3. But I'm thinkin now, why waste the EN1 when I can just swap the motors and I'll could use the EN1 instead if its just the carbs making it not run.

soo much thinkin...makes my head hurt. Has anyone else had trouble like this with thier Dellortos? They haven't been tuned either but it should still work.

Kurt, do you have that Dellorto speciallist in italy's email?

Thanks guys,
Colin
