First of im new to open racing and only ran akra for a year. So i have a open 460 with a new tillotson alky carb and it will not take off out of the corners it just Bogs down and spits and sputters for about 3 to 4 laps then it runs great. I have even tried to start it and let it warm up some with a couple warm up laps and it will take around 2 laps to come out of it. Here is what im running 460 block 356 cam 1:3 roller rockers forge flat top piston. 32/40 valves and 65lb wit
springs. With a 35mm HR series tillotson alcohol carburetor All is completely new and carb new this year.

So you have made no adjustments ?
This is going to be a hands on approach .
This appears to be a flathead carb on a ohv engine .
Turn the high speed needle in 1/2 turn at a time till it clears up .
Maybe turn the low in a 1/2 .

I am not tilly expert . All i have seen though the flathead carbs are overly rich on ohv engines .
