need help with a couple issues with motor startup Options

[MrHyde]

got a couple issues I could use some advice on. 2316cc with weber 44's

1: CHT i gave a micro1000 CHT gauge.. its not reading anything.. i have it under #3 cylinder and its connected to the extension line and heat shrinked and on the gauge its red to + and purple to - . this is the only way it will go as one is a male and the other is a female connector.

2: carbs are running lop sided. right bank is pulling about 5 and the left side is pulling 12-14. this is with the idle speed screws backed right off. Any adjustments on the right banks mixture screws do pretty well nothing until closed and then is sputters a bit. Adjusting the mixture screws on the left side start making changes to the idle and sound of th engine immediately..

3: voltage gauge is not reading anything but the idiot light does go out once the motor is running

4: fuel gauge and the temp gauge ( in combo gauge) are both pegged.. I think this is most likely ground. i'll check that in a min. I only put a couple gallons of gas in the tank.


side note.. once motor was warmed up doing cam break in the oil pressure was steady at a hair over 20psi andi only have one small drip of oil on one valve cover, which i'll look at when i do a valve adjustment.

Hmmm. You know what. Maybe I'm going about this the wrong way. Any adjustments that I've made trying to get this gong have been the same adjustment to all 4 barrels of the carbs. Maybe I should start thinking of this one cylinder ( or even one bank of carbs) at a time. I ran the motor up to 3500rpm to set the timing at 27 deg and the motor sounded pretty good. My wife said she heard the odd sputter but that could be because I still had the linkage loosened up. What I will try tomorrow is...
Unbolt the barrel nut for the linkage cable on the slave side. Get it out of the way and just deal with the idle. Then try adjusting the air bleed screws on the 1/2 side to see of the suction drops (at idle). Then, Perhaps screw in the idle stop screw on 3/4 side to open up that side a bit and see if I can sync is that way. See how it runs

Your hypothesis that 1/2 are pulling 3/4 along for the ride makes sense and it could just be pulling in fuel but no ( or little ) air on 3/4. Hense fouling plugs.


I'm going to sleep on this. Anyone else want to chime in a thought please feel free.
