Little back ground on setup first.
Blowthrough triple webers running t04e at 8-15 psi
Okay what i am experiencing is i believe spark blowout.
Does it at all varying psi just not to later in the rev range. Ie: at 8 psi right at 4,500 its like i hit a wall and the motor will not rev farther. Same at 15psi just a little later in the band.
During the wall like feeling and the revs not going anywhere wideband falls off the map pig rich. To be expected if its not lighting it off.
The kicker is if i back off the throttle just a little BAM its back on. This leads me to believe the spark is getting blown out at high pressure. Running stock br6es-11 gaped down to 20 thousandths. I have tried everything in between that and stock.
Blaster 2 coil. Does it with the flame thrower coil as well. Wires are new ngk 8mm. Kinda stumped here. I have never experienced blow out so i dunno. But the revs will just sit at 3,500 until i back off a little bit then it seems it can burn and off i go with a vengance.
