|350||Ok been driving it a few days this week. And it runs really good now. However when I idle it up with the idle mixture screw I lose some the ability to tune it. If I idle it down its to low. So I got to get that figured out. But otherwise I got it going great. Thank you aging.|

|RWENUTS||SEt them where it idles best!|

|350||In other words where I have it set is all I can get if I turn either one a half a turn it runs worse. And the one I am having issues with I can only go a half turn from all the way in and that's it can't go in or out and it get crappy. Sorry trying to get this whole thing down pat.|

|350||Ok can do. And. If I go more than a half turn out on the one screw the idle gets bad I can't go anymore either way.|

Always set timing with vacuum plugged off.
Get a vacuum gauge and tune your mixture screws with that. At 1/2 turn out you might be a little lean at idle now. If no gauge try at 1 1/2 turns out.

|350||Also do I set timing with the vacuum advance plugged off|

|350||I got a timing light and no tab. Where we switched motors it wouldn't fit we put parts off of one on to the other. I can't remember y now. But I drove it today and it done good. Just that bog at the bottom. I only have about a half turn of adjusment on each one. Haven't moved the pump shot. I can't idle it up or I lose adjusment and it needs to have a little more idle. Lol u have been dead on so far so tell me where to start and I will. Sorry I am on a cell phone so its hard to type all this.|

Or do you have a chrome timing cover?
Like I said drive it with it hooked to manifold, tune the carb screws and see if the bog is curable by adjusting the pump stroke.
You can get bolt on timing tabs.
And good timing lights for 60 bucks.

|350||Also I have gotten good at listening for spark knocking lol|

|350||Not sure to be honest I don't have any timing tape or a any way to set it the timing the little plate that is used to set it is gone. Gotta set it by ear. Bad idea I know. And what should I do first?|
|09-24-2012 06:48 PM|
One thing at a time!
Wait on adding more timing and see if the stumble goes away.
You gotta be carefull and listen for detonation.
What's your initial timing at now?
|09-24-2012 06:19 PM|
|350||Yes sir. Its running a lot better I can't believe that I had hooked up any other way. Thank u so much. I lost my dad last year and I have been stummped ever since he was always the one to help me. He told me he had it rigged to lose power. But I never thought of this. I think if I give it some more base timing it will git rid of my bog taking off and get it close to perfect. Thank u again.|

No. Actually better, smoother running motor. More responsive. Plus you get to tune a slightly rich condition out of your motor by fine
tuning the mixture screws.
The 460 in my truck loves it. Runs like crap if I try to run it on ported.
Just listen for detonation though. It'll sound like a slight knocking at idle. Mine does but goes away when it warms up.If so pull your timing back a couple degrees. Bad detonation sounds like rocks in a tin can. Real hard on pistons.

|350||Ok thank u. And would running off manifold vacuum be bad|

|RWENUTS||Look in the carb with the motor off and stroke the throttle. Look for a strong shot of fuel on each side by the venturi. If not experiment with the rod position till it's better.|
