The carb is a 650 eddy. the carb performed great on the 355. what about the vacuume, if it is low that could cut the motor off cant it
Be sure the battery is fully charged.
Look to be sure the plug wires are correct- 1-8-4-3-6-5-7-2.
Be sure the timing tab is correct for the balancer mark.
Be sure the distributor isn't off a tooth.
Set the initial timing to about 10 degrees BTDC.
Screw in the idle screws until lightly seated, then back out 1-1/2 turns.
Back off the curb idle screw until it closes the blades, then crank in enough so that you see the blades just start to open some, then add 1/2 turn.
From this point, if the engine's not suffering from a vacuum leak from the intake gaskets, carb base gaskets, or from any other sources- the engine should start.
If it won't idle or idles too low, give it some more idle speed (not idle mixture, do that next).
The engine may need to warm up to operating temp to idle right, depending on if you're using the choke or not.
