messing up my ignition

Ok I'm going outside to do exactly this, except the cam thing. I don't want to take off the valve cover, If I understand correctly, at tdc it will point toward one or four plug correct. I don't agree on selling the truck for $100, last time you said $300 and since then I've put about $150 into it since that saucy comment, not to mention all my hard work and my neighbors hard work and you guys and all your work...sooooo how about $1,000,000 oh yahhhh.

I've done exactly what you said except the valve cover removal. I tdc the engine lined up the teeth and had the rotor pointing at one or four? Checked black and white wires with neighbors volt meter. Put the one with 12 volts when ignition was on to left side of resister. Put B post wire on the same left side of resister. took original black and red wires one pos coil post. Finally I have c post going toward neg coil post. Got some sputtering when cranking it over and nothing as soon as I stopped cranking the starter. I'm hoping I flooded it and I am waiting.

You got the blk/ white wire as I said to use with the clear whittish connector?

 

WHO is your daddy!!!!!!!!!!!!! Say it!!!!!!!!!!!!! Say IT!!!!!!!!!!!!!!

get a timming light and set it and youll be Pimpin till the next proplem!

 

Crap almost had a 100$ truck!

 

personally I would make athe matchbox wire red B and blk C incase you have to remove them later and dont get them confused and pop the box later

Yes your help was a huge, if not the main reason the truck is running. I am so thankful for all your advice, however the wire you wanted me to connect to the left resistor post was dead per the volt meter. I checked the other and it had over 12v when the ignition was in the on position. I think the wiring of this truck has been severely altered. You should see the battery side, it would make you crazy! Thanks again, next the weber gets a rebuild. weeeeeeeeee. Then the clutch and then and then and then my wife reminds me about our income verses expenditures.

 

Ps went to my first meet. Dogs and Rods. Stalled on the bridge on the way. The wife was supper inpressed....um she hates this truck officially. Stalled in the driveway of the meet. We met some really nice people...even some ratson friends! They even gave me some grate tips on my dying weber. As in... rebuild it.

Wayno PM him.

He dont come on here unless his trucks broke.

Ck it out. I like the truck. Its a good truck! keep it alive.

 

I think he said he needs a clutch soon so he will be back on here later

 

 

I went visiting him today, the truck runs allright, it sounds a little funny, but that might be that he is running a stock exhaust manifold, and all my L blocks that I DD have headers. Are webber carbs supposed to have a fuel return line back to the tank? His truck/engine has the return line, but it is not being used, also the vapor separater is gone, can the stock fuel pump put to much pressure into the webber carb without the return line? I don't know a lot about downdraft carbs, I run SU types, I kinda understand them, at least enough to adjust them. I guess next time I go over there I will take the work truck to compare the dist. wiring. wayno

No. I don't know any carburetors that require a return line. Instead they were fitted to control emissions (to lessen heat soak) and to mitigate vapor lock. It isn't to help the carburetor.

 

The fuel feed system for Weber is exactly like the SU type carburetors. They both have a fuel bowl and needle valve.

one change to your setup I might suggest.....move the dizzy ground wire to the core support or body. The bolts on the engine really aren't a very good path back to battery ground. I've had guys fighting with poor running because they had the wire grounded at the base of the dizzy. I had them switch it....they were amazed at the difference in how it ran....especially at higher rpms. :)

My SU type side drafts have a fuel pressure valve(on the rear carb itself) and a fuel return line that goes back to the tank, his truck also has a fuel pressure valve(on the inner fender) and return line that has been taken out of operation, I repeat, can a stock fuel pump over pressurize a webber carbarator? He says he has it timed at 12 degrees before TDC, he also had it idling really slow, I never seen a L block actually idle that slow before, maybe it's a downdraft carb thing, that J block I had would run at maybe 500 rpm with a downdraft. He is going to rebuild the carb, so I think we should wait and see if there is an improvement, if there is, then he has some other things that need attention to make it a reliable daily.

No. Not if it is working correctly. The Datsun-Hitachi sidedrafts, in fact, use the exact same inlet needle valve as downdraft Hitachis.

 

Most SUs don't have a return line. None of mine do. Certainly the newer ones from emissions-controlled cars might. A return line is helpful to reduce emissions.

 

Idle speed spec is probably around 700 or 750 RPM. Most engines can idle lower than 600 RPM if the carbs are in like new condition but as the throttle shafts wear they let too much air in and won't idle down that low.
