Carb Adjustments?
Can anyone tell me if there are any adjustments I might need to make to my carb after putting on Dual exhaust... The 350 ran great before doing this job, and now when the secondaries open the engine backfires and falls on its face. Any Ideas?

Whenver you do anything with fuel consumption or emissions always check your ignition, your timing, and yes your fuel/air ratio. Your engine timing might be a tad retarded (opposite of advanced), which means a few extra degrees of advancement may be all you need.
