- Tired of cleaning your small engine carburetor and curious about mechanical fuel injection? No, this is not electronic fuel injection for a small engine. Far from it still! Looking for a boost in torque power for a small engine? Engine bogging down? The mods of a tillotson TCT carburetor tested here on a predator 212 non-hemi engine gives an instant torque performance increase in my 212cc engine and I'm looking to put it on my snow thrower and one in my stock appearing race go kart.
There isn't much for small engine carburetor repair with this carb. It's a mechanical fuel injection carb for small engines such as lawn mower, snow blower, mini bike, go kart, rototiller, and several others. With so many people needing small engine carburetor cleaning this fuel injection alternative (not electronic - keep in mind) is a great little alternative. For some who may be doing a small engine rebuild of a non-working engine and need a new carb, This small carb doesn't need much adjustment at all with the mechanical fuel injection.
HP stays the same, but this is a great predator 212 performance mod for starters getting into boosting their speed up in front of their buddies on off road go karts, or mini bikes. I'd check out a mikuni for some more serious push power, but this carb was a great fun and is going on one of my engine builds for sure. I bought 2, one is going on my snow thrower to give it a little more pushing power and torque for when the snow is thick. - Авто та транспорт
On my Predator mod snow thrower i would rather have the higher speed. I want to go faster and rarely have an issue with it bogging down. I will stay with my stock carb thanks. Nice job on the video. Very informative.....
Same.
Very useful video, thanks!
Interesting stuff!
I do like the fact that you are building their your own Dino and such, but it would be really nice to get the torque and horsepower numbers together. Torque is very important but overlooked sometimes. I'm building a mud mini bike and would like to know torque values so that I'm able to get a good ratio of power and torque
Good review
You need a vacuum fuel pump for max rpm and max power on a tct
What carb would you recommend for a ditch witch 1330 Trencher with a Honda GX390 engine? I'm thinking it couldn't hurt to have some more torque while digging.
So what was the tuning you did?
Can you please post a video just directly on how to tune the tct carb?
Nice
Nice info. Ideas for future videos if you have not already.
Aftermarket camshafts - bottom end - mid range torque increase with that injection vs. Carb. Aftermarket head, w/ & without cam, pistons, injection ect. Then try fuel addives for power - marvel, E85, nitro ect. You probably got all those written down by now. Top o the day
can i stroke a 670cc or is it done?
How does the tillotson TCT affect fuel consumption?
What is the actual model number of the carb in you video? It does not look like the ones that Go Power Sports sells. I bought the TCT from them and it has (TF-8A-6C 110 177) stamped on the side of the casting. At 0:05 on you video, your carb appears to have a brass inlet tube above the fuel line. What is that? Neither of the Tillotson "mechanical fuel injection" carbs that Go Power Sports sells have that brass tube. The only Tillotson carb that I can find on the internet that has that same brass fitting on the side is a "dual fuel" carb for a generator that can be used to meter propane.
started my ducar for the first time today let it run 10mins with the royal purp break in sstuff im gonna go another ten mins but wen i give it gas it dies out with choke on with choke off it wont start i just keep working out my slaping hand lol
I'm considering one of these for a mini bike build have u don't any comparisons on test driveing with both carbs
Not online, but i have done. The tct needs to be with it's proper "version" on a build. There is a version for stock exhaust, and a version for if using a header. They keep rpm low with bringing up torque so swapping to smaller gear makes an improvement for speed. With a header, stock carb goes faster than the original tct, but the tuned tct meant to be run with header has the edge over stock carb if using header. If you intend to further build the engine, the tct is limited. If planning on keeping governor in and getting the most from a small build with cvt the tct is great choice.
i dont think mikuni has anything to worry about!
Me channel i wonder if it would be worthwhile to use the gear box from a front tine tiller on a cart or something probably be slow as hell
But would probably out pull any other cart thats ever been built
It's got a wacky clutch on it now. I've got my eyes peeled for an of road kart, might be interesting to try out for sure.
@@megoingfast thats just something ive been thinking about for a while
What is there for 420 cc clone , I have a 15 hp on my snow blower now. Great video
459cc new red engine at harbor freight forged crank yep lol like it needed that but hey all good to me big valves thin performance light weight piston i own one i pulled it apart its a darn nice engine amazingly so get one

How does it compare to a mikuni?
It can't, really. It has a very narrow venturi. Both can increase torque, but the mikuni can get gains in hp by raising RPM and sucks fuel. The tct can keep rpms lower while upping torque which is GREAT to keep rpms lower than a point where and engine could hit a failure point (stock flywheel and internals). However, if a mikuni is on the engine, you'll likely need to compensate other parts of the engine to prevent failure and get the most from the carb fuel delivery and increase in air as well.
i am thinking about doing that but with a Tillotson 212 hemi. How would that go?
Overall close to the same. A very good pairing around 8 HP with a bunch of torque that can rev higher than the predator.
@@megoingfast I thought that the 212 Hemi was 10 hp
@@charliemaybe yeah, well, marketing likes bigger numbers 😉😉. I have a video comparing the tillotson 212r with hemi flat top piston to the predator on a Dyno that explains it all. Tillotson website gives a Dyno chart also. It's a great engine, don't get that part wrong! Serious torque!!
What's the actual Horsepower an Torque of a Stock Tillotson 212?'
10hp. 12hp on the 212R not sure about torque
I'll have the 212r on the Dyno shortly, but sadly there were quite a few "manufacturing issues" I've worked with a little with tillotson, but... Yeah, even I just gotta wait and see. Breaking the engine in on a mini bike right meow. Hope to have this done soon and video posted for the Tilly.
Do you think this would be good for a mud motor?
Really depends on pitch prop, diameter and other mods. The torque will be there, bringing back rpm, but changing props is your biggest gain on boats.
Going to try the TCT on my Mud-Skipper Twister (with prop adapter and Tillotson 212e), it uses 2-blade aluminum long-tail props. More interested in torque than top speed, and not really interested in making recommended mods for higher rpm's than what the engine is initially designed for. After taking it out yesterday, I can say that bone-stock the Tillotson 212 is a stronger engine than the stock HF 212 hemi, (of which I've owned/run many). $40 is not much money for an adjustable carb.
yeah we got one on our mini bike and its really disappointing. it made the bike slow and not very good at all. would not reccomend, and i really cant figure out the advantage of these ive read every word on the internet about these things and still dont really know how to tune it, plus it just doesnt seem to do anything.
if you can get hold of a "wideband and vacuum gauge" this would shed some light for you.
@@mafosa9563 thanks for the input, I have one for my truck, never considered using it for that. I'll have to adapt it somehow
Calling this a "fuel injection" is simply wrong. It is a carburetor with enhanced atomization and the conveniance of not having to change the needles for a tun.
How do i know it's not an injection? Well simple, you need either of two things, an electronic fuel pump and an ECU, or a mechanical connection to the crankshaft for the injection pump.
you're forgetting one thing: diaphragms.
I don't know if this specific carb does it as I know nothing about it, but some carbs (usually on 2 stroke boat motors) use diaphragms and the engine pulse to literally inject pulses of fuel into the intake, in addition to the fuel pump which is also driven by the intake pulses. Usually it helps deliver fuel while needing less of a venturi, and therefore less intake restriction at the high RPMs they see.
This Tillotson one may or may not operate on the same principle, but it seems to have been executed poorly. The whole point should be less intake restriction, not more.
Exactly right... this carb is neither "mechanical" nor "injected"... There is no mechanical apparatus that pressurizes the fuel, and the fuel is not injected... If you dig into the operation, it has a variable needle similar to a motorcycle carb... the advantage is the atomization of the fuel. Stock carburetors on these motors are the worst ever, and are easy to improve...
NOT saying new one does not work or is not an improvement... Just saying that the term "mechanical injection" is very misleading...
Can you give any information on your dyno build?///////////////////////////////////////////////////////////////////////////////////////////////////

I did check the mail 😄
Try out cheap amazon carbs to see if there any good
The 22 mikuni kit is on my list. The pb1k should get swapped from my tillotson as well. Any one in particular you're thinking?
me sure I have the Massimo 200 so I was looking into the Poweka not sure if that would work on yours but their is also a Hiaors that fits the CTU 200 either one or something equivalent would be awesome to see they are both cheap coming in at under $20 which is why I’m curious and they are both sold on Amazon I just typed carbs for Coleman mini... thanx bud great content 👍🏻
The PZ 19 equivalents, or the ones that are the same as other branded $10 carbs? 16100-ZH8-W61 and 16100-ZE3-V01? I purchased both of those listed just in case those are it. Had adjustable F/A and idle so looked good no matter what use to try out. Will be picking up a few more, but PZ 19 and PZ 20 is a pretty small carb where the slide control has been a pain to work with in the past when I did small engines.
me that all sounds great whatever you choose will be good thanks
Horsepower results for ewe! Hahahaha!
