Idles with throttle fwd

[Walker2]

I have a '79 Chrysler 115 Model 1159H9C. It idles ok around 800RPM but only with throttle somewhat forward. Idle screw about 3/4 inch away from resting place on block. throttle cam rolled a bit forward. Needless to say I can't put it in gear without killing the motor.

I have timed it at 32 BTDC with the Clymer's static timing procedure. I have syncronized the throttle linkage and choke linkage. I have also set the fuel air mixture idle screws all the way in then 1 1/4 turn out... think I might try a new set of points. I just acquired the motor. Probably years since it ran. Thanks

If it's running?? you probably don't need points.

In the drive on the hose, the idle should be 1100-1200
In gear, in the water the idle 800

Stalling when putting in gear, idle too low, bearings in the lower unit seizing,
water in the fuel, carbs set wrong.

Thank you Jeryjerry05. I'm thinking carbs set wrong cause it just dosent run without throttle being quite forward. In this case, what should I look for... float settings? I've tried tweeking the mixture screws while running... no change in rpm

your idle is too low if that is 800 out of gear. Should be around 1100 like Jerry said. check out Frank video - one of the top links on this chrysler forum.

Thank you skiDad. I cant set the idle because in order to just get 800 RPM the throttle has to be quite fwd. Idle screw 3/4 inch away from its resting place on the block

The top 4 posts in this forum have procedures for setting the linkage.
Called a link and sync. by FrankA
This will help set up the throttle/idle.

Where is the air screw set at?
Initially it's set at 1 1/2 turn out.
It's possible yours needs to be set further out.
Saw a 84/85hp that needed to be set at 3 full turns on all 3 carbs.

Thanks you guys. I carefully followed all Frank's procedures before I posted this. The problem is that you can't adjust the idle with the throttle set forward and it won't run any other way. I will try messing with the carb to try to remedy that, then I can set the idle. Jerry, I have the mixture screws at 1 1/4. I'll try opening them up some. I appreciate your help thanks
