This Tillotson came on my KR project and I’ve been told I can’t get rebuild kits for it which is a shame

Try Tillotson. They re-released kits for "Vintage" HD series carbs.

Otherwise, I'll swap you a Bendix.

Here’s the interesting Petcocks. Anyone ever seen these before?

Lots of old Timken bits are still around Dave, just no a simple book order though for most. I used them for years on various big inch engines, they are simple to tune well.
That on has the adjustable high speed jet kit, but an odd bit of plumbing on the carb itself. The fuel inlet is the side hole (plugged on yours) and the top is a vent line to the top of the fuel tank which is how they flow fuel without the benefit of a float bowl. I always ran oversize fuel inlets (oil line fittings) modified needle and seat (for more flow) and the high speed kit. I used to have a fair number of bits around but most perished over time. I can look though and see what I still have. Does it have the competition diaphragm cover with no provision for an accelerator pump?

Hi Robbie,

Thanks for the information and yes mine has the competition diaphragm with no provision for the accelerator pump.
