Well had it out for a good ride last night. Seems the bog is still there....
Engagement is 4200 ish. I think I have the chokes sync'd properly from your thread. cables not too tight and looked in with a light.
Sitting there idleing and then hammer the throttle and the engine dies out. rpm about 4000 and thats all. Seems to have a bog in deep powder also.
Feather it and/or pump the throttle and takes off with no bog. mid range runs great and has good throttle response.
It is the take off and under 20mph where she bogs out but wont die just blaaaaw at 4000 rpm.
Here's the weird part...open the hood with left hand and crack the throttle and seems like it responds like it should.
I have also notice that the DG can is putting exhaust under the hood. it is not plugged but cracked where it joins the stock exhaust.
Just soooo much to think about. But that is why these forums are here!
