Took it off with fuel in it. When I  slowly moove the throttlelever it pores gasoline instead of spraying like I'm normally used to.
Should I take it apart and clean it and use the aircompressor to get the dirt away or any other suggestions or things to look for ones it's open?

The carb is now apart, the only thing I see is that the floatlevel is way from what the manual says.
Could that be a reason?

IF your float is set too high, then yes, that is a problem. Gas will be pushing into the carb. If it is cold outside as you say, too much gas makes it even worse to start. It's easy to flood an engine in cold weather.

Gave up the eddy carb and took the Holly 750 vacuum from my Chrysler 300 -69, it's running good but needs moore fuel to give the right responce.
Ordered a Proform 750 from Mancini since they are on sale and tune the car again, I'm just happy the enginebuild went good. :bigsmile:

Here we go again :banghead: The new proform gives just the same symptoms, impossible to get the car started when it's cold. It's now a few degrees
above zero here and 3 different carbs gives to much fuel. What's wrong with the timing when the car runs when it's warm but not cold?
Changed plugs and coil but no difference. Since the first startup after the rebuild things just got worse. :bricks1:

The Proform has no choke?  And you want to start it when its 2 degrees out? :lol:  Sorry about that.  Will it start with the holley vac sec carb with a choke?

Tom,
That's just the problem. All carbs I tried have choke and trying to start makes the sparkplugs wet and you are lost. I've checked the plugs and
the fuel almost dripping of them and I don't use much throttle. It's freezing here so I don't get it. :dunno:

Yesterday I fired my 383 after over a month of sitting at 0 celsius with no problems. of course fuel evaporated from the bowls (holley 770 vac seconday)but it started after some cranking. maybe you have too uch advance? does the carb pop while trying to fire it up?

if it is running too rich then the choke is restricting too much air flow , you probably need to adjust the choke pull off to open the flap a bit more as soon as it fires

Could start it after manually blocking the choke at open and full throttle and yes willard, the carb tends to shoot the fuel out.

Set timing to 16-18* at idle (was 6-8) but can only reach 30* at 3000rpm without vacuum connected, was told to keep it plugged.

Carb idlemix adjusted and the floatlevel is OK so tomorrow I will check again if it starts in the cold, it's about 38-40*F.

Another problem I noticed was that the choke doesn't stay open when the engine gets warm. I guess you can adjust that but Proform
doesn't deliver a manual with the carb.
