https://www.burtonpower.com/accralit...b120-83-5.html Hi has anyone had a issue with the above piston, I have used the twice now and both times piston number 3 followed by 1 and then 2 melted and 4 fine. Block bored and sleeved 244 Kent cam Accuspark distrubutor Twin 45 dcoe webers (with airbox) Carter fuel pump Tuned on dyno running 32 advanced timing First rebuild only lasted a day Second rebuild last 3 race meets and on the 4th number 3 piston distorted. Running standard fuel tank would fuel surge cause this problem. Could it be the air box? We are out of ideas what is causing the issue being that the same piston go in the same order. Is it the design of the piston with the thin lip melting. Any help would be greatly appreciated
