No, On the 2-step. Sometimes it's clean and runs perfect and then once in awhile it pops.
We pulled the carb off tonight.
It's a 4150, pn 8106B
70's in the front with a powervalve.
74's in the back with a block off.
The front squirters are 28's
The secondaries are 31's
Thanks for all the tips everybody.
We have a pair of squirters that are 32's
We'll probably block off the other powervalve also so if it does backfire again it won't knock it out.
I think my brother has been talking to Ken Jones.
