Dat73z Posted November 28, 2022 Author Share Posted November 28, 2022 (edited) This AM I swapped back to 45 pump jets and added a bit more volume. When I put in the 40s I was attemting to tune for the fireball out the exhaust when unloading the motor between shifts which I now suspect was due to losing timing. I suspect 45s are a good size from what I recall earlier this summer but I won't know until I start shaking things down again.
