Burning tip off spark plug!!!

[JustAddDirt]

if you are burning off all the electrodes I would increase jet sizes on all corners.
if you are burning off the left side 1357 plugs.
increase the left side of the carb jetting 2-3 on both left side jets in carb, or get a tapered carb spacer.

It's been on the left side every time... I'll bump up jet size ... Could it be coil,msd,plug wires or something like that?

Intake gasket leak?

Check the timing at higher rpm to make sure it's not going to 70 or 80 degrees

May sound funny but it's g force related. It's getting lean on left bank because of g force. Fuel wanting to go to right bank. Run the jets on the left bigger or just richen up fuel mix on that bank

May even want to try running float higher in carb for that side. Fuel could be running away and can't be sprayed properly

Timing would affect ALL plugs, not just left bank
