Small Engine Won't Run Without Choke - RustySkull Productions

[@richardf2220]

Thank you, after watching a bunch of videos on this subject you are the only one to come up with the answer to my problem.

[@dewijenkins254]

Can't wait to try this tomorrow on my pain in the ass trimmer tomorrow 😂

[@devonlamb11]

I figured id add that when the choke is on it creates a vacuum throughout the whole carb and actually draws more gas and less air. It means your engine is no longer able to suck enough gas thtough the lines because of blockage. Check the fuel diaphrams in the carb! Great video thanks for the help!

[@markluxton3402]

Correct. If the settings worked before, and no one messed with them; the jet adjustment is not the issue.

[@BikeNutt1970]

Thanks for the video it helps me getting my weed eater back after being bogging in full throttle. When searching I only find video explaining engines with 2 adjusting screws, this the first I found explaining engines with just a single caprator adjusting screws. Now I get my engine back to work 😀😀 thanks...

You’re welcome Salle :)

[@jeffreyhines4876]

Your segment on trimmer run on choke only was very helpful!

[@RSPYT]

Good I’m glad it helped you :)

[@philliplawerence5784]

The screw you're adjusting in this video is the high-speed jet. You can adjust it as you have shown, or a much more conventional method can be used, which is: 1. Start the engine, allow to warm to operating temp. 2. Pull throttle to high speed and hold, adjust the high-speed jet screw in/out to obtain the highest speed with as little vibration as possible. (That's it for the high-speed jet.) In 99% of cases the low speed jet never needs tampering with, and improper setting can cause several other bad conditions. However, if you're ABSOLUTELY SURE you must change the low-speed jet setting, for most carburetors the jet is on the top of the carburetor covered by a polymer cap. Remove the cap, start the engine and allow to run at idle (about 3000 rpm), then SLOWLY adjust the low speed jet in/out until the smoothest operation is reached at the highest speed. Then reset the idle speed setting for running at about 3000 rpm. Re-install the polymer cap. Either of these adjustments can easily be performed in 30 seconds or less.

[@tonymayhew191]

It's been my experience that the L and H jets have nothing to do with this issue! Usually there is a chunk of crap stuck in the inlet side screen. Or if it is a 4cycle engine it's got crap stuck in the main jet and requires you to remove the fuel bowl and poke the end of a small spring in the hole in the jet. 😉

[@vdog4799]

Thank you for making this video bro. I know very little about carbeurters and this was a good source for info👍

[@AndyWhittaker-e5q]

Did you do the video on the Husqvarna 128DL string Trimmer?

[@perrydear]

Just did a stihl fc?110 bush cutter with these symptoms so l took the carb appart assuming blockage not enough fuel. Did that twice to make sure l put carb back correctly...( pot is legal in Canada). Felt rather frustated, checked a few more UTube vids, l started to hear the words " plugged spark arrestor" over+ over, sure enough that was the bulk of the problem. My early inspection will now include a look at the spark arrestor screen... Enjoyed your video! Nice job! Thanks Perry

[@alfredgarcia6608]

Excellent, thanks 😊.

[@donaldskaar101]

[@AndrewFroude]

Thanks for your helpful content. I followed your recommendations however they didn't work, only to discover 2 things: 1. The Choke on my engine was incorrectly labelled i.e. in reverse 2. The throttle cable was too short causing it to flood on restart Thanks again and I hope that this may also help others.

[@RSPYT]

Is yours an SGS?

[@AndrewFroude]

[@nishg9886]

Your Tops

[@stephensmith413]

I've got and SGS 5 in 1 hardly used because its a pig to start. The main issue is that the compression is high and it kicks back whacking my knuckles. There is no problem with fuel flow. I decided to fit a new plug as it was black and sooty. It doesn't start easily on choke and I wondered if more air in would weaken the mix and reduce the compression. What do you think?

I have no idea lol

[@charlheaney270]

Well put together vid mate learned alot. Essentially im a bit stuck with what the answer would be for myself and my 49cc small engine pulls nice, chugs well but doesnt fire and start up going to check the spark sleeve as it wasn’t the most secure. Plugs fine, has fuel and 2 stroke

[@perrydear]

Check the spark arrestor screen...must be clear of carbon.

[@shanontabisher5580]

I want to know why my stram 52cc is cutting off and wants to switch off when I realees the throttle(accelerate) and theirs still alot of fuel in?

[@charlheaney270]

So what im wondering is what would you check in order first to see what happened

[@amkenbrough]

I have a Parkside strimmer, when I pulled the string to start it, it slapped back and broke off the red choke for regulating it. So, what to do with it now. ?

[@RSPYT]

So the choke leaver is snapped off? You can buy new leavers. But I’d be tempted to just try to stick something to the remaining bit. Is there anything left of it or is it completely gone?

[@begara6451]

I have a very similar trimmer and it has on/off on the choke lever. Should the lever be in on(lower) position when startin the trimmer or in off(upper) position when starting it? I noticed the trimmer shuts down when I press the throttle while choke is in off position. So does that mean off(upper position) means choke engaged and on(lower position) means choke disengaged? My thoughts are off means choke disengaged and that trimmer should work when choke is in off position but it seems I am wrong with that.

[@missionman4539]

Awesome 👏 Thanks for the video !! Petrol ? Gasoline?

[@RSPYT]

Thanks, yeah petrol is Gasoline. The full name is Petroleum Spirit.

I can get my Chinese made Strummer to start on choke but as soon as I so much touch the choke knob to put it to run the motor surges really high and dies out. Can't get it to start at all in the run position. It's is a barrel type cube carb with the idle screw in the center of the throttle knob and the high adjuster on the backside of the carb. Do help if I have been able to present my predicament clearly.

if you are lucky like me and have the right brand carburetor. this info might help you there should have the L screw on the top on the throttle cable part, probably covered by silicone cap or plastic just peel it off and find the L screw

[@gomezthegreat]

Hi, I have a similar problem. It starts easily with the choke and has a stable low speed run. Wen i open up the throttle it dies. I tried to adjust the screw and went trough every possible setting and it sill dies. I have the same engine that you shown in your video.

[@j.harris7228]

Change your 2 cycle oil

[@OhZjuchi]

Please help I bought a brand new brush cutter 52cc 2stroke and I fiddled the whole day with the air fuel butterfly valve screw and as I put the choke off the engine dies? What else can I do I even added more oil (as it's never ran before)

[@RSPYT]

If you bought it new then it shouldn’t need any adjustment. You can try setting the screw back, if you adjusted the butterfly then that’s the Tickover screw. You can start it up and turn that screw in until it stays running :)

You are putting the choke on instead of off by the sounds of it.,

Is it normal for a trimmer to start with the choke on..? Mine says to pull the string a few times with the choke on, then remove the choke and pull the string again, but mine starts running as soon as I start pulling the string with the choke on. It also starts at full throttle, I have to press the throttle a bit and then the revs drop to idle.

Yeah that's alright, usually you use the choke to start an engine, it's only really some small engines that are a bit fussy lol.

Why do you have to move lean screw if it’s never been messed with before.What causes rich/lean to get out of wack.

[@RSPYT]

Air pressure can effect it, damp air if it’s a foggy day or something. Or if it’s a very dry hot day it’ll need Richening. Or the quality of the petrol and oil you’re using can effect how it runs and starts

[@rolandbrawner8282]

The "twisty-turny" thing didn't help me (or my engine). I did some ethnic engineering by putting a screw in the little shelf above the choke lever to restrict it from opening completely. Works well now. BTW, the choke lever works in the opposite direction on my engine. I haven't given up yet, next step will be to take the carb apart and verify there are no restrictions in the main circuit.
