Re: Ford 4.9/300 Propane Problems

Depressing the primer button at idle on my 300A equipped 327 that I'm happy with stalls the engine. On my Commodore that's lean under load with Model N-L reg' depressing the button at idle also stalls the engine. Reading posts in this thread I understand that shouldn't be the case, I always thought ...

Re: Lean acceleration and steady speeds above 50 mph.

one trick i used to fix my 225 setup was to use a switch ( in my case ecu controlled ) to trigger a HP shut off solenoid, mounted on the LP side , and short cut some mixture ( via a mig jet pill ) to the throttle body initially i used vacuum/ boost as the switch but found tps position to be an easi...

Re: Lean acceleration and steady speeds above 50 mph.

I used a Jaycar mixture display years ago, they aren't accurate Please check the PCM and see if it is throwing any fault codes. Lots to ponder, Jaycar unit at least confirms what I felt.

3.8 Ecotec. Kit, fitted by a licensed mate with lots of experience, car had been back to him many times over the years, has always lacked power on Gas. Most problems I've ended up finding and correcting, e.g. cracked porcelain inside body of plug after he had fitted them, some time after unfortunate...

Impco CA225FB, LPG Model N-L regulator, on 2002 Holden V6. Have a simple led mixture display tapped into an ego sensor, it goes full lean (lights out) on acceleration and light load cruise. Idles a little rich, but at least that gives it a manifold full of acceleration air fuel. Not running feed bac...
