we were pretty close to putting the propane system from our 86 dodge omni in the 80 brat until we got the factory carb working ok finally. Running it on propane is a simple switch if you have the parts (tank lines regulators and carb) it will run, run clean, run all the time. not as much power though unless you raise the compression ratio somehow. different pistons or shaved heads.

Nice set!!

This is excellent work! and very helpful as the passenger side floor is currently thick wire mesh and the drivers seat is slowly sinking. what should i use to treat repaired metal if i don't have any magic black goo like you have?

what disc brakes will fit on the rear of my 1st gen brat

Removal of the Nippondenso 420667100 084200-0260 anti afterburn valve (specific number from mine off my 1980 1st gen Brat) is recommended by experts. General Disorder being the main expert. If you have the Hitachi DCJ306-15, remove the AAB Valve prior to doing any carb tuning.

Thank you General Disorder! I unknowingly had an anti-afterburn valve that worked only some of the time. So naturally I took apart the carburetor hundreds of times. losing the original settings while re-adjusting it each time the anti-afterburn valve got stuck in a different place. After removing the valve all sporadic symptoms went away. Back fires a whole lot more now on account of the exhaust system ending 3 inches past the catalytic converter. I call it an audible oxygen sensor, allowing me to further tune it till it doesn't burn so rich. once warmed up it purrs nicely now. at one point it got almost 29 mpg before i messed with anything. now it gets 15 to 19mpg. Any tips on fine tuning the Hitachi DCJ306-15? or anyone have one setup just right already? Choke set at? air screw? fuel mix screw? how many turns and such? or.... now that it can be relied on to bolt through intersections with reliable acceleration, I am just burning that much more gas by hot rodding it around??
