Man I really want to try one of these 4B-TT, but the price tag is killing me. The new Ninja is even more affordable...Any fathers day specials floating around? Where are the deals?

K so I have a Nova engine thats a few years old and havent been run for that long so I wanted to see if I could get it running again.
The thing is its all clogged with residual fuel and junk so I have to take it apart and clean it. Cant get the sleeve out though, its jammed so hard in there and I have nothing to pull it out with. Ive tried heating the case with a heatgun but its not helping.
Anyone have any good ideas about what to do?

A thick zip tie through the exhaust port, and turn the crank will usually do the trick. The sleeve will pop up and you should be able to take it out.

Yea tried that it only cuts the ziptie in half. :lol:
Im beginning to suspect that it wont be possible to get this out without damaging it.

either a strong old toothbrush with the bristle end cutoff our a plastic rod to push the sleeve up from the bottom is what I use to remove all sleeves, probably a few thousand

If it is still a bit stubborn I would recommend soaking in wd-40 ,and/or heat up the block a bit

Toothbrush didnt work. Thing is the exhausthole fits almost perfectly with the hole in the sleeve so theres not really a ledge to get leverage from.
As I have already tried to heat it Im gonna try your other suggestion and let it soak in WD40 for a while.

Push it up with the toothbrush from the backplate area. Use it on the bottom of the sleeve ;)

Yea that didnt work either it was way too stuck.

But I got it out anyway!
Fabricated a small aluminium piece from an old steeringarm from an RC18B that fitted between the intake port and the exhaust port, but not long enough to hit the case. And then I just pressed it up with the piston.
I can tell you though, it was STUCK cause I had to really use force to get it up.

I use a zip tie and it works perfect every time. Get a large zip tie (put piston at BDC) and run it through the exhaust port and start turning the flywheel. Should pop up enough for you pull it out with your hands.

Works lie a charm!

Yea I did that but it didnt work with this engine cause the sleeve was stuck WAY too hard so it just clipped off the ziptie.
As I said the engine has been sitting for years with fuel in it, so it was all clogged up inside.

Forcing a delicate sleeve out with a toothbrush, NO WAY

YEA im surprised to hear these amateur ways of removing sleeve from so-called professionals, that jp tool is second to none, i have NEVER tried anything else, as the ways mentioned can only do damage, the jp tool, you just pop it in, and pull it out, it has rubber that expands in a sense and grabs on, so when you remove your not PUSHING with a toothbrush on the bottom of a sleeve, wich happens to be the weak part, and im sure the stubborn ones, it HAS to make them slightly out of round. pm me i can direct you where to buy for under 20$...
