OK I'm doing one of 2 things. blocking off the hose at the manifold and cuting a little piece out of the hose at the port so it is free flowing at all times. Or pulling the tree out of the water jacket and plugging everything but leaving the port open. What I have found is that with a 2 barrel I don't get my advance quick enough until the engine is completely warmed up and with only driving my car in the summer it isn't needed anyways. Thanks for all the input. Rick
would this reatard issue cause my car to lag when i hit the acceleretor? im running a 250 I6.by the way when i blow on the hose for the retard it just blows right through, nothing happens.
Grabber if yours was like mine I'll tell you how it operates. The back side of your dissy get a vaccum from the manifold until the engine is warmed up. This helps with a more complete burn for emissions. When warmed up the little tree that is in your water jacket at the thermostat closes the vacuum and allows the back port to just open to the air. Then you are operating at just on the front port on your dissy, and that vaccum is different depending on RPM's. I just read an article that said that you should use ported vacuum on emission cars, ported vaccum is a vaccum port that doesn't open until about 1000 RPM's and use full vaccum on non-emission cars. I put full vaccum on my dissy and it raised it to about 18 BTDC. Now this is at idle. But now I sit in the car and smash the pedal down and there is no lag at all. Now to be honest I haven't been able to drive it yet because of weather but I think any problems now will be jet sizes and or adjustments. Hope this helped, let me know if you change things and how it affects you. Rick
The fuel we buy today is formulated different than it was back in the day. Today's gasoline is doing a better job reducing emissions than the 40 year old technology emission devices that came on our cars.
