my weber 45 doce wont idle when i start it i have to regulate the rpm to keep it alive but when i go to ajust it the rpm it shoots up to 3k-4k and stays there and some times when i get it to idle around 2k the moment u hit the gas at all it gets stuck at 4k the venturi leeks gas would that be caused by fule pressure is at 2.1/5 psi but could it be a float hight problem

chokes 36
idle jets f8 60

Check your float level.
Check your needle valve.
Check for vacuum leaks.
Set your idle.
Buy an AFR gauge.
Set the rest of your carb by looking online tutorials on DCOE 45 or buy a book.

For my stock port 36mm chokes were too small, I went to 38mm.
