The Stovebolt Site Forums The Shop Area Engine Shop Dual carbs not working correct! Please try to help!

Been about a week now on the new carbs. Put another 200 miles on it. Everything seems to be perfect now (knock on wood). I have no gas smell what so ever in my garage now after parking it. No gas smell when accelerating heavy. Cant comment very well on gas mileage due to the fact im so heavy foot now because of how it hauls [censored]. Think the idle screw is a bit lean because it take a few second of cranking to start. Might just give them a 1/4 turn out and see what happens. Still need to sync the carbs. The auto chokes on these ones are even set better. Never touched them yet but this time around they dont make the engine idle extremely high when cold. This time around its just perfect.

Need to think about what to do next year about gearing and a transmission. In a few seconds third and im not making use of the 2000 ish torque range very well.

Installed a HEI system and very happy with that also. Will post up a thread soon about that install.

Oh another ting to add. Now that the engine is smoother and quieter at higher rpms. i hear a bit of a chattering sound when around the 2000-230o rpm area. I have adjusted my valves before and will take another look but is this sound somewhat normal? Its not super clicky loud but just a dull chatter. Happens when cruising and under any load in that rpm range.

Im trying to also understand knocking or pinging. I have the timing only set to 10Deg right now so i think i can rule that out. Is the pinging on this inline that noticeable? I honestly dont know what it sounds like or feels like in order to watch out for it.

Try retarding the timing a degree at a time until the "chatter" goes away. With the modifications which you have made, the "Book" no longer is relevant. Now it is the "seat of the pants" adjustments which matter.
