Re: [Chrysler300] Timing and tuneup on the 300E ........................

My problem was that (probably due to weak advance springs) the mechanical advance was coming in way too early. Since the adjustments depend on rpm changes (I used an instrument tach), a small change would cause a runaway in speed because of premature advance. At least that was my conclusion,

The rebuilt distributor allowed me to adjust the carbs below the threshold of mechanical advance coming in so I could tell if I was going too lean or too rich.

I also had my AFBs rebuilt by a professional carb restorer who replaced all my bent and deformed linkages with brand new parts.

I am still not satisfied with my idle, but its because of my skill/experience level.

I think a good mechanic can do much better for me.

Hi Tom,
Assuming that your dual AFB's are similar to the ones on my H, I suggest that you follow the procedure in the service manual for their adjustment.- Works great for me.

I also can only get the 90 octane gas and set the timing by trial and error - timing light does not work due to slippage of the mark on the harmonic balancer.

Good Evening Out There Everyone in 300 Land!

Quick question ............................. doing a tuneup on Big Red!
She's been sitting for nearly a year. Drained out the gas, cleaned the
tank, replaced the plugs - gapped at 0.035" now for timing and carburetor
adjustments.

I live in South Florida - a steambath here! On the carburetors, should
they be ONE turn out, 10 degrees BTC at an idle speed of 500 RPMs? By the
way, for fuel, I use 90 octane recreational fuel - it's the best we can do
down here!

Any other suggestions would be helpful! Thanks to all responses in
advance!
