Well i ran into some delays. after switching to a vapor for fuel i soon found some valves thet were leaking pretty good. Talk about making one backfire!!the motor ran good on gas but when i went to propane with those valves leaking it got upset quick!! so i got the head off and doing another valve job (I had one done a year ago but he done a ****ty job) so im about a week behind schedule.

The Throttle position sensor just too the beating of its life!! Good thing I no longer need it HAHAHAHA!!!

Crappy coupler!! = death to something!!

ya i got it firing right again. that stupid gizzmo 2 step unit is pure junk!! im throwing it into the garbage. It had everything all jacked up. So i def dont recommend it to anyone. It seems like it does not work well at all with the rb motors.I will be switching to a Msd setup. I know it works good.
