Re: 209 continental engine on propane

Hi everyone been a while .. rebuilding a 209 continental industrial engine converted to propane and was wondering about the heat riser settings in the exhaust manifold ( typical old 2 piece that bolts together ) should it be set differently than it was for gasoline. the casting simply says on --off...

Re: What does the RCV valve do ?

Add to that. It is only used with fuel control systems that use vacuum to control the secondary diaphragm. The standard orifice bleed hole in the fuel control fitting was not large enough to allow rapid response of the secondary diaphragm. The regulator control valve would open if the throttle was ...

Re: Bought my first propane van

I can't answer a lot of that. I thought it'd be worthwhile keeping the propane since it shouldn't be too expensive to do so and you'll have the range from both fuels. 20 odd % less power. I reduced that loss by using a spreadbore holley. Lp Gas through the primaries and petrol through the secondarie...

Re: Bought my first propane van

I wonder if the engi e has been built for propane i.e high compression.
If not, dual fuel would seem a logical option.

Lifter pump up ?

When my V6 ecotec has an intake manifold explosion and runs rough for a while after it, has it pushed an inlet valve open and let the lifter overfill ?

Re: Vaporizer temperature, contaminants, and separate thermostats

Sorry for the essay and wordy post. Thanks for going to the trouble. Appears our Gas in Oz must be pretty clean, rebuilt my kit (300A and Model E) a couple of years ago after more than 20 years of use (suvived 2 cars and 3 engines) everything was reasonably clean and functional, coolant side was a ...

Re: Air line oiler as simple valve lubricator

2 stroke oil isn't the biggest factor in 2 stroke emmissions. Also 4t or 2t only have to pass our lax emissions laws. They can't ban 2 strokes, only non comliant engines including diesels. Your point is noted but our current ADRs are equal to Euro 5 and we are moving towards Euro 6. How is that lax...

Re: Air line oiler as simple valve lubricator

The 2-stroke oil is only in there as a test because it was in the shop and should be fairly harmless to burn I don't know about anywhere else but there are rumblings about banning the sale of new 2 strokes in Australia because of how much pollution they produce compared to 4 strokes. 2 stroke oil i...

Re: Air line oiler as simple valve lubricator

Neat, but does burning oil in the combustion chamber add to or reduce the welding then blow torch effect that destroys softer valve seats.

Re: Engine likes more advance with iridium sparkplugs...?

I run fixed mechanical advance on my 327, last time I looked it would have been around 30 degrees, also running an additional 14 degrees of vacuum tapped below the butterflies. Dual fuel (at the same time when the secondaries are open) so I use 98 octane petrol. I'd run more timing but don't have a ...

Re: Based on your experience ?

For the most part I think there's more oxidation and crud build-up than wear. Yer it's pretty cruddy. Gas nozzle appears hammered, sharp inner edge, bit chafed as is the gas jet, and one of the guides has a fair bit of wear. I guess if the guide was sticking it would hamper travel, so just reduced ...

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...
