Canuck Tech :

Is this currently running on diesel?


No. It runs on LP gas, hence the model number S 80 LP - JTRK. There is no carburetor since it is already a gas, but I want to eliminate the LP system. It is old, the tank is out of code, etc., and I don't have a good way to fill it either.

I have never seen a kit to convert one of these, and there are not a lot of these in the US. If you want to convert it to a carburetor you should look at the Solex PICT 34-3. These were used on some early VW beetles that were carbureted. You will need to fabricate an adapter to allow it to bolt on. This model of carb has a built in automatic electric choke you wire up to get power when the ignition is on. Side draft CV carbs like motorcycles use, and some foreign cars use, like MG's can be easier to install, but they are much harder to tune. The PICT 34 is so universal, it shouldn’t require any jetting modifications. When fabricating the adapter keep an eye on vertical clearance, and consider clearance for some type of air filter. I have bought several of these PICT 34 carbs through the years on ebay, you can normally find a good deal if you have some time to shop. If you have any more questions I am here to help. Good luck, and Thanks for using Just Answer.
