HEY! ENGINE COLLECTORS...TELL ME MORE?
« on: February 08, 2012, 03:03:33 PM »
Going through an old Buyers Guide from 1980 I doodled  some art work for $$$ or one of these beautiful old twins...however after waiting for many many months...I got a check instead.
Humm?
Wonder if that engine would have been worth a BUNCH OF MONEY TODAY? MAYBE NOT?

Only if you had never unwrapped it and didn't scratch the box.  If it was still in the original USPS package it would be priceless.  If you wanted to fly it, not so much.

Thanks Russ...for your reply about that strange ol Fox that I tried to glean...way back in 1980
Bye the way....have you heard from our friend Bob Kautzman lately? Wonder if he is still adding to his collection?

With two venturis and two needle valves, I wonder how much pain to get a good needle (s) setting?

Last I have seen of them, they were going for big bucks. I haven't seen any for sale for several years. They are not all that hard to adjust the carbs on. Just takes a few times back and forth between carbs to get them balanced. Saito also uses two carbs on their twins.

Like a lot of twins Dukes had the same trouble that a lot of twin manufacturers had,namely feeding both cylinders equal volume. Also he had a few parts that needed adjustment so most including mine went back for a visit at the factory. As a glow it was mediocre. Did I mention that it wasn't the best on fuel economy either. I converted it to ignition with Bill Carpenters aka CHS electronics twin system and installed HB40 carbs on and it was a reliable runner. To reduce the extra needed ignition accessories I converted again to diesel with Davis heads. This gave me the advantage of being to adjust the timing and fuel mixture to each cylinder individually.It then ran about the best that it was ever going to do. It ran well enough that a diehard Fox lover had to have it for a project and I sold it off to him.
Do I miss it and wish that I had it back, not really. There were so many other better designed engines that were less problimatical that I never looked back with any warm feelings about the critter.

I'm still trying to talk Donnie out of one of those ST 46s he has squirreled away.

Agreed Dennis, I have read about one of these engines that needed the rear cylinder to be very much richer in order to run evenly and the owner surmised that this was due to the cranks rotational force feeding the boost port on the front pot whilst acting against it on the rear.

It would seem that spinning against the ports is the more inefficient method.

Cheers.
