This tutorial is very good, i finally got my flywheel off, time to replace it

[@DrPuddinBuns]

Your "how to" videos are fantastic. Far more helpful then any others I've found so far. Thank you for the help.

[@danielbremner4142]

Thank you. Took me a while to find this video.

[@How-To-RC]

Easy starts are great. They also prolong the life of the pull cord 😄

[@SirDrakeNewcanon]

4:52 dont do it that way! Use a ruber hose! It will not harm the piston and the spark tread! Or use an impact driver!

[@timbo8958]

Thx.. That helps me a lot

[@joshpowellmedia8022]

Thanks, real easy to follow

[@MiniBikesStore]

thanks for feedback.

[@neonurph5636]

you may not see this but its worth a shot. ive done everything you have to remove my flywheel but its stuck on. any tips to get it off?

[@bikersfireworks4860]

Help the fly wheel bolt snapped any suggestions

[@_doboj8702]

nice video

[@MiniBikesStore]

thanks

[@Gamen4Bros]

Great video! But easy pullstarts break faster in my experience

[@MiniBikesStore]

with easy pull start you need to pull slowly gently, then the spring will turn the engine automaticly, if you pull agressive you can damage it

[@johnstoops4103]

Where can I get pull start for easy pull

[@mrphelps9942]

Just a suggestion - I would use a wooden dowel in the spark plug hole

[@bugk1738]

For chainsaws I have used a coil of cotton rope inside the cylinder. Remove the plug and feed a cotton rope inside the cylinder between the piston and cylinder head. Stops piston travel without risk of damaging cylinder or piston.

[@moshazza5684]

hello mate. my bike was not starting due to broken pull start, so i saw a youtube video that tried to start it using a drill on the flywheel. i did that but my 10mm nut is rounded off bad. i have bought a new flywheel to match new pull start. any idea how i can get that bolt off?

[@Potato37184]

Cut a slot in it and unscrew it with a screwdriver

[@davidrickard9686]

Mini Bikes Store hi can you plz HELP me I have a flywheel I need to get off but it’s stripped (the screw) and I was how to get it off with a stripped screw

[@SuperMorales88]

I have a pocket rocket mini bike and the back wheel is stock. When I pull the start pull it starts but the back wheel keeps running

[@DelacruzAj.]

Same lang din ba sa 4 stroke mag kalas nyan sir

[@Ace01010]

can u link where u got ur flywheel and parts from

[@MiniBikesStore]

hi, you can get them soon from our shop www.minibikes.store

[@ant5761]

My flywheel screw is striped how do I fix this plz

[@WUTANG-CLAN]

I had the same problem, i used a dremel (or similar tool) with a mini cutting disc, and i made an even cross grind into the middle of the bolt, then used a phillips head screw driver instead of a ratchet and un screwed the centre bolt out.

[@markshone4606]

Hi i seem too have same pull start as you but it isnt grabbing flywheel too turn it over

[@MiniBikesStore]

if you hear clicking while pulling, you need to replace pull start as it is damaged inside

[@howardbriggs7663]

The bolt to hold on the replacement Easy Start flywheel on some units requires a M6 30mm bolt rather than the original M6 20mm available from any hardware store.

[@How-To-RC]

Your local store doesn't sell beyond 20mm for m6 bolts? I found a 400mm m6 bolt at my local yesterday

[@robertgorman9520]

I got a new pull start (same engine as in the video) when I try to start it the pull start just get stuck and doesn't retract? Any help please

[@I_did_something10]

Need new pullstart

[@TomGTARec]

This video was really helping me fix my son's mini quad but the bolt to fit the new flywheel has snapped and I can't get it out will I need to buy a new engine now? Fml.. Lol id appreciate any help if possible

[@MiniBikesStore]

ThomHD you will need a screw extractor. Simply drill a pilot hole in the broken fixing and screw in the LH-threaded extractor for easy removal of broken screws and bolts.

[@TomGTARec]

Mini Bikes Store thanks alot for the reply, I ordered an ez out extractor right away and today it arrived, the bolt is too strong in there it stripped it even with the ez out having a very good bite it seems to be very wedged in there is there any other way or do I need a new engine? Thanks again man I appreciate the help. Subbed.

[@MiniBikesStore]

hi, you can try to bring it to your local car garage, maybe they will be able to remove the broken bolt. if not you may need new engine.

[@TomGTARec]

Mini Bikes Store Yeah you're right that's probably my only option other than new engine now, thanks for all your help mate 👍 all the best.

[@MyiMpakToLife]

You dont damage the fly will but you damage the piston and the thread in the sparkplug

[@honda3189]

Ja jak odpalałem z wiertarki to mi się sroba ujebala 8.8 twardości . I latam teraz Magneto bez sroby jak narazie.

[@Tino63287]

Can u buy a pin cuz i cant fined my one

[@stijnlouwerse6442]

Your first example of losing the bold didn’t work for me a part broke when I demontaged it

[@ChinnyRusso]

Is removing flywheel really needed? My pull start is broken I can just buy one new don’t see why buying a new flywheel also is really necessary…..?

[@danielbremner4142]

My flywheel is so herkky jerkky. I cannot get a good smooth pull. It seems to lock up every half rotation of the flywheel. Next step for me is to pull off the flywheel to see if anything is damaged, like the drive shaft.

[@monicafiallo1344]

When we pull the pull start bike won’t start but flywheel keeps rotating what do u think can be the problem

[@MrAirjordin23]

Monica Fiallo there’s suppose to be a flywheel key on the shaft the fly wheel sits in. The key is a small metal piece that hold the flywheel in place. If there isn’t one when you take off the flywheel you have to buy one. Without it the flywheel will just spin on the shaft.

[@MrAirjordin23]

That or you didn’t put your spark plug back in

[@rickycass5363]

My pull start keeps slipping each time I pull it is this the fly wheel please

[@MiniBikesStore]

if you experience the clicking sound while pulling and no pression then pull start is damaged inside, you will need to replace the pull start

[@rickycass5363]

@@MiniBikesStore I don't have any clicking noise I just have the pull start slipping it's not turning the fly wheel. It's only a couple of months old. Just got a new pull start today and it's doing the same thing. Slipping each time you pull it

Does this work on a 49cc

[@MiniBikesStore]

yes, it is 49cc engine

[@mitchlec8916]

I was given an old used pocket bike that hasn't ran in 4 years, I took a look and there's no bolt holding the flywheel on and there doesn't seem to be any threads to have a bolt in place... is this normal or is there something missing?

[@MiniBikesStore]

please send us an picture to [e-mail] I will try to help you

[@mitchlec8916]

Just though I'd let you know that I figured out the issue. Whoever owned the bike before must of stripped the threads inside the crankshaft where the flywheel bolts into. I'll make new threads and try that and see how it goes.

[@dennisjuniorreid884]

Plz help my bike is pumping gas good but i dont have no start.... Plz is there other way to start it

[@mitchlec8916]

@@dennisjuniorreid884 I would check to see if you have spark.

My fly wheel screw broke off where can I get a new one

[@seantapp9616]

Hey also the one half is still threaded in the engine

[@Stackedwithcash]

Should the cool touch the flywheel?

[@MiniBikesStore]

no, the coil can not touch the flywheel in any point

[@howardbriggs7663]

see this video on how to set your coil distance from the flywheel kzbin.info/www/bejne/ZqiYfXVur82Kp6c

[@steven20919]

Had a pocketbike just for one day with easy pull start, and the easy pullstart mechanism broke. so fuck easy pull start

[@yfn5971]

[@MiniBikesStore]

keep trying, put wd40 on the bold and leave it for a day then try it

[@honda3189]

Jest ściągacz do tego i kosztuje w pl około 40 zł . Nie ma co kombinować .
