I've got a problem with my T1 1600 DP. It won't idle and hesitates severely when on the road.
The compression is O.K. on all 4. About 120. There is plenty of spark at the plugs. (White Fire) The timing is set at 10 degrees BTDC for the 009 distributor. The gas is fresh and the float bowl is full. I haven't adjusted the idle too well because of this situation. The engine's been sitting for about a year but I changed the gas and oil and the carb, PICT 34-3, is new. Dwell angle is fine.
I'm sure I'm leaving out information but those are the highlites. If you have helpful suggestions I'd really appreciate them. Thanks in advance.

ENGINE PROBLEM
Usually, the 009 is timed with a light. You're looking for maximum advance at about 30 degrees, and let the idle advance fall where it may. Use the following procedure to tune your carb, and if it doesn't work, post again. P.S. Just cause the carb is new does not mean that it can be ruled out as a possible problem.
1. First make sure the engine is hot (fully warm - operating temperature).
2. Shut the engine off.
3. Hook up the tachometer and adjust the fast idle screw (the screw that rests on the notched cam) out until it does not
touch. Then turn the screw in until it just touches, and then add 1/4 turn more.
4. Turn the volume control screw (the little one on the left side) all the way in. Then back it out 2 1/2 to 3 turns.
5. Turn the volume control screw (little one) clockwise until the rpms drop, then turn it counter clockwise (watch the tach
for the highest rpms) until the rpms drop. Again turn it clockwise and this time stop at the highest rpm that you found
between the previous turns. NOTE: This must be done REAL SLOW to let the carb react. Now turn the volume control
screw clockwise until the rpms drop by 20 or 30.
6. Adjust the idle using the bypass screw (the big one) to an idle of 850 to 900 rpms.
