The Thor models share a common design and many parts. If you cannot find the info you need below or on the individual Thor model pages, check the Top 80 section for a wealth of info that is common to all Italian paramotors.
PARTS AVAILABILITY – an "*" after the item means we usually stock it. We can get most other engine parts but it may take a week or more. We are first a paragliding school and the rest of it we do when we have time. Contact us to order.
Carburetor* – The Thor 100 and 130 use the WG-8 The Thor 190 and 200 use the WB-37. If your engine is not purring like a kitten in the mid-range, you need to perform the midrange modification on your carburetor. The Thor 250 has a custom Polini carburetor (we do not stock this one). It is more like the Bing which has a fuel bowl.
