This is my 1st post and I'd like to thank Matt for inviting me to join your site. First of all thanks for all the comments on my engine and you guys have a very cool site BTW. It has been a long process in building this engine. I saw an original Tri-Power back a few years ago at a swap meet and also on The Samba. It was really weird and cool at the same time and I always wanted one. Since they were so rare, even rarer than Judsons, Okrasa's etc; I knew I'd have an impossible time of locating one so after learning how they were made I decided to make my own. The center carb is a stock Solex pict with one important differance, it has a air correction jet of about 220, so it leans out at a higher rpms. The 2 side carbs are 24mm Tillotson's, they do not have accelerator pumps, do have adjustable jets, and work only on vacuum. They are controlled by a semi progressive linkage setup that includes a torsion spring that bends at lower rpm's until the tension is surpassed and then it allows the side carbs to open up.
The engine runs just like a normal 36hp, but it does have a little better top end then before. My mileage is at about 28-30 mpg so it has'nt changed much, as far as performance I can pass on the highway a little faster than before. Thanks again for all your comments, if you have any questions, let me know.
As far as Matt's super secret project... :-X :-X :-X ;D
