This video measures the venturi and bore of the HL Tillotson Carburetor clones. Some carburetors are marked "Tillotson". They are available online for just under $14. These are intended for chainsaws, but they add great performance on Honda & Predator 212, 223, and 224 clone engines.

So, how did they measure up?:
FULIN = .750 venturi with a 1" Throttle Bore
Tillotson "marked" Clone = .785 venturi with a 1" Throttle Bore
HD Golf Cart Replacement Carburetor = .865 venturi with a 1" Throttle Bore (This one was $19.99)
The product title for the Tillotson carburetor in the first link is "YOFMOO Carburetor Carb Compatible for Stihl"
The first carb I received was the "FULIN" brand. I was pleased with it and ordered another. The next carburetor I received, from the same link listed above, was branded "Tillotson" and had a larger venturi. I've ordered more since then and have been receiving carbs branded "Tillotson". Keep in mind these are Tillotson "clone" carburetors and NOT likely to be genuine. It's my belief that they are likely using genuine Tillotson block stacks on a cloned carb body. Get these while you can, if nothing else they're worth the price even if used for replacement parts.
The Harley Golf Cart Replacement Carb was from the "Rop Shop" I ordered thru the Jungle site.
Two of these are chainsaw replacement carburetors and one is a replacement carburetor for a Harley Davidson Golf Cart. The performance gain of installing one on a 212 DUCAR or 212 Predator is definitely worth a look.
Are they worth the price? I think so. How much do they cost? Well, that may change, but I paid less than $15 each for 2 of these carbs including the tax and shipping. The Golf Cart Carburetor was $19.99. I don't know what the current price will be when you see this video but I'll put the link where I ordered mine if anybody wants to check them out. I will likely be buying a few more of these for other projects as the Tillotson style diaphragm pump carburetors are among my favorites. One of the LCT 179cc engine builds coming up may receive a Tillotson as well!
There will definitely be more videos made on these Tillotson clone carburetors. Some ideas I would like to try: Add a 2nd pump stack and see if I can get one of these gas carbs to run methanol fuel. Maybe add a 3rd pump stack triple pumper experiment? The Predator Ghost 212 would also benefit from a Tillotson pumper type carburetor. The venturi size on some of these Tillotson carburetors is larger than the venturi size of the Predator Ghost 212.
I added a couple of brief clips at the end of some possible upcoming projects. I have several gas generators I really should get going. And my boys also uncovered a couple of 420cc Predator engines I had stored away in the barn that I'd forgotten about. I was thinking there should be a 301cc engine stored somewhere. This might get interesting....
If you guys want to have a look inside these Tillotson carburetors check out @KainKustomGarage Dan has lots of great videos on rebuilding/restoring these HL Tillotson carburetors and many others. Since these are intended to be "chainsaw carburetors" makes perfect sense to check out a premier chainsaw guy!
If you guys enjoy Racing Karts and Race Video Footage be sure to check out @franksoutdoorlife Frank has lots of great Kart racing videos with excellent commentary.

Easter Egg in the video: Did you notice I was being attacked by a mosquito the size of a small bird in the video opening scenes? Well ok, maybe it wasn't that big but he did seem determined to have a bite. No mosquitos were harmed or injured during the making of this video. It wasn't from a lack of trying though.
