Holley/Demon Carb stumble
Now with all of that.
I have decided to buy a new throttle shaft or base plate(still 1.75 butterflies)
Like i have said above the primary just work!
Secondarys is were the stumble is happening. and is also were i found a couple of pieces of alu that was kinda acting like a reed valve in the fuel transfer slot of the secondarys. they look wider to me as well compared to the primary transfer slot.
Another reason i want to replace it is that this was a used carb and had holes drilled in the butteries, that are to large. I would soldier them up and re drill, but either the throttle shaft is bent or the the butterflies.
When i took the carb off this time i noticed that the butterfly/transfer slot was less than a square on the primary side and the secondary side had one blade that just showed the beginning of the transfer slot, and the other had it completely covered up.
If you want to see what came out of the secondary transfer slots go back to post 78.
