Zenith vs tilly performance

[Synchro909]

You would need to turn the intake manifold upside down and test with a downdraught as the intake is a restriction.

I think updraughts are way cool. Trying to work out how to use two of them on a RHD.

It's not a big deal to toss the original inlet manifold. I've made a new one before or I could use a B manifold. I think they have a larger cross sectional area.

I checked with our local Tractor Supply Store to see if they had a "small size" (the usual size) new needle and seat. They had some that looked like the Marvels, but they were for Ford tractors and with kits (like $50). The best thing to do would be find a Ford Tractor Dealer and see what they have. Be careful because the Marvel seat thread pitch is 27 threads per inch. (The common fine thread size is 24 threads per inch.

I've never ran my Tilly, but a friend who borrowed it for 2 years, said it ran super. It's loaned out to another friend, "someday" I'll get to try it out!

Hey Bill, when you get that back can I borrow it while I rebuild my Zenith?

I found he zenith produced a smoother power but the tilly seems more responsive and delivers more power at the pedal
