I melted number 8 tip (ground strap)again no clue why a/f 10.8-11.1 with 15* Im makeing 17 psi and using tr6 plugs. Its only number 8. But the plug looks like its getting enough fuel. Should i go to a colder plug?
it could just be the tune. I melted a few tr6 plugs, then switched to br7ef plugs and melted those too. it ran like crap after that so i pulled the motor apart and found a melted spark plug boss as well
