I know people say that backfiring isn’t good for an engine but I’m curious on how you can get a backfire or a loud pop?
Get your needle to stick or give it a real rich mixture lmao. Rev limiters can give you pops because they cut the spark dumping fuel down the exhaust.
If you have the stock carb/emission controls, disconnect the deceleration fuel cutoff solenoid on the carb...
I used to key bomb my KP60 starlet in the Lyttleton tunnel in NZ, so loud it would stop traffic, soo much fun! Also great fun in parking buildings. god i miss that car!
Not really. Any afterfire is unspent fuel that can wash the cylinder wall. Ends up in you oil. Gas is not a good lubricant.
My truck is a 1986 pickup with the 22R. When I bought it, it had sat for 5 years. After I fixed it up, I cranked it to find that the exhaust has broken off right at the muffler, though not completely. It pops as soon as I break ~2500 RPM.
