Re: after impco 425 hose connections....

C3H8 was asking for more information so that you get the best advice and he is a world-wide authority on LPG systems. Although the Model 425 mixer is commonly used on straight conversions, it is straightforward to use it in a dual fuel system.

Re: 327 build - fine tuning

It probably wouldn't hurt to experiment with running less total advance. I would think that Vortec heads have better combustion than slant six heads and 65CrewCabPW found that his Dodge pickup runs well with "16 - 18 degrees or so at WOT and high rpm (3600)". http://fuelsforum.rasoenterprises.com/vi...

Re: Toyota Camry CNG car tank expiration

Welcome Tim. It would be more useful for visitors to this site and are in a similar situation if you had this discussion in the forum. It would also be good if you could share your CNG experiences with us.

Re: impco 200 super lean!! help

Welcome to the board! Please fill in your profile so we know where you're located.

Presumably, you have "blow-through" instead of a "blow by" system.

It would be useful to know the primary and secondary pressures at the Model E's test ports. Photos would be handy too.

Re: rebuilding engine - some questions

I am far from an expert with respect to rebuilding engines but my understanding is that quench is used to induce turbulence in the combustion chamber. The greater the turbulence, the faster the flame propagation. The net effect is a reduced need for ignition advance. Therefore, the ideal quench woul...

Re: Closed loop system install

HI Davey54. Welcome to the board!

The SV is installed in the secondary test port in the side of the converter. With the vapour outlet pointing downwards and the cover facing you, this is located at about the 7:30 position.

Re: Propane tank won't fill after running on empty

While it's possible that is the bulk tank is substantially cooler than my car's trunk-mounted tank (which is typically parked in my garage), I would expect that, within a week, the bulk tank should approach ambient temperatures. I find that my local station in Fort Erie commonly has trouble filling ...

Re: Propane tank won't fill after running on empty

I have sometimes had problems filling the trunk-mounted tank in my car at some propane stations during the summer. My local propane station often has this problem with other cars too and the attendants believe it has something to do with the temperature of the tank, especially with underbody tanks e...

Re: need help improving my mpgs, getting 6mpg

Welcome to the board! Ignition timing is important to both power and fuel economy. It would be very useful to chart mechanical and vacuum advance. A setback (adjustable) timing light would handy but timing tape will work too. Do you have a the vacuum advance permanently capped off or were you just d...
