Pull Start Won't Pull Sometimes

[Hellion]

What photos exactly you need? Engine or compression thing?

Heck man, give us a pic of your engine just for giggles. You never know, someone could take one look and go "bingo, I know what is wrong!" Photos might show something amiss, broken or out of place on your engine.

It sounds like you might have intermittent flooding of your combustion chamber. My 17 horsepower lawn tractor engine does the same. If there's gas in the tank, it will drain into the cylinder (via the faulty carburetor) and fill it up, causing hydrolock.
Depending on how much fuel is in the cylinder, it will be very difficult or impossible to start, without draining it first.

Aside from that, if I were you I might be inclined to disassemble (or remove) the recoil starter to verify there's no binding or other malady.

This is some mystery. Hope you can solve it, bud.

Thank you I thought the same thing because when I remove the spark plug, it pulls easily. I removed the pull starter and tried to spin the crank, it was still hard to turn when spark plug is on it. So starter is ok? Hope I can fix that or I'm gonna send it back to where I bought it.

Sorry for those silly questions What should I do now? How can drain the gas?

White settlement! Thats poboys backyard. must be something in there water

Yah my pred engine filled with gas. bad carb. just make sure you turn of gas each time you are done. still something wrong but keeping the gas off keeps it from filling up when not in use

pull plug, tip engine slightly, pull on cord a couple times. see if gas pours out?

Pictures!!!!!!!!! no one respond until we see some pics!

Cant help if we dont see what we are working with here. A selfie with you and the engine maybe or better yet the infamous shoe on head picture of yourself. so we know you are real. lol

Did it ever run? when you say engine levitated???? what exactly did you mean? wish my engine levitated. flying mini bike! yes!

It ran few times, then I didn't start it for one or two weeks. Then this problem appeared. Crank side of the engine heavier than pull starter side, and when I pull the cord it levitates a bit because pull starter side is lighter.

So um i guess no one is aksing because we all assume it is on something but. Is this engine just sitting there on the floor? bolt that sucker down to something and then pull!

and PICTURES!!!!!!!!

Drain the oil from the "left" oil drain plug, and refill in the "right" dipstick hole.

And duct tape the engine down so it stops levitating.

I filled the oil engine from left dipstick, I didn't know
Does it really matter?

And guys, calm down. I'm gonna add photos.

Looks like a brand new engine straight out of the box.

Well...

Clean it up and Take it back to the store...

Show us the recoil starter and carburetor side! Might be something amiss there, plus we can see the engine's name, usually.

You know, if you're just running your engine on the kitchen floor merely for your own amusement , that's part of your problem right there. The engine needs to be bolted down like others have said. It helps starting immensely as the only thing that receives the pulling motion is the starter...as it should be.

Once you get oil in the engine's cylinder by getting it operational, it's quite typical for your compression to increase by a small factor because oil seals the piston and the piston rings in the bore/cylinder and heat from combustion expands the piston in the bore, sealing it as well to a slight degree.

Can you do video of this hard starting issue? Post it to Youtube and share the link here.


This is one of the most painfully tedious threads in recent memory.

I'll agree. It's like the whole "how do I fix my dirtbike's powerband" question but if it took you 2 forum pages to explain it to the uneducated 2 stroke owner

Did you snap the power band? I think BMI sells replacement bands.

Your name confuses me. Do you have to drive to the States to get a Predator?
