Still having problems. Over the weekend, I removed the motor and put a known good back plate with reed valve on it. Swapped out the carb to a Walbro WT-324. Swapped the throttle lever and arm out of the Borg Warner carb and put it in the walbro carb. BTW it is upside down copared to the walbro. Tried to run it. Could not seem to get enough fuel in it. With the standard starting settings, needles opened 2 full turns, I could only get it to fire fully choked. It is pumping fuel as I can flip the prop and suck fuel up from the tank to the engine. If It just crack the choke open a little, I can get it to run wot but it will not idle. I ended up opening the needles to 4 full turns and could get it to run with the choke fully open at wot. But still no idle. Thought I might have another carb issue so swapped the carb out again with another WT-324 that I know was good off another engine I have. Same results. I cant figure out what the problem could be. There are no air leaks in the fuel lines. Swapped those out. I took the back plate back off and sealed it with RTV. Only idea I have left is that the throttle lever might be messing with the fuel flow. With it swapped around, the butterfly is opening in the opposite direction. But to fix this, I would have to re-engineer the throttle set up on the airplane. Only want to do that as a last resort. Also tried different spark plug. Made sure the head was on tight. What do yall think? My arm is sore from cranking on this thing.
