Poor Fuel Economy? Rebuilt with SR Kit

<< < (2/2)

OutlawDrifter:
Cliff, after bottoming out the APT adjustment with no off-idle stumble or lean surge, I pulled the top.  I was wrong, the 52M rods were in the carb already.  I did make some adjustments to the hanger to get the rods to fully seat in the jets.

I also checked the float level and it was set properly as well. 

I checked over the distributor and the VA is not holding vacuum and advancing the timing, so I will have to replace the can.  The mechanical is working just fine. 

Cliff Ruggles:
You just found one of the problems.  Without the vacuum advance, the timing is retarded at cruise, which kills fuel economy.....Cliff
