walked into ace hardware with my sleeve pinched it with a hose clamp, got home was way tight heated it up with a map gas torch, and pushed the piston to where I wanted it to be a let it cool down. put it back to gather, fired right up like it was new, honestly can't believe it worked, it was super ghetto how I did it.
Heating up the head first, on a worn out engine, is a SURE fire way to make it NOT start. If the sleeve is worn and the compression is already gone, heating it up before you start it is only going to make the already too big sleeve even bigger, the compression will be even worse, and it surely won't start. 🤷🏻
My nitro rc runs good but I need to warm it up with a blow dryer or else it won’t start and when I just run it and I shut it down it won’t start again until 10 min when it’s cooled down
typically if it won't start when warmed up (e.g. after running for awhile), then the engine is nearing end of life - that said if it's working for you OK that's all that matters! I wouldn't recommend trying this, I haven't done anything else with this engine except start it up a few more times...hopefully one day i can get a cheap roller chassis to try it out in
@@VBshredder He's referring to not being able to start it because there is TOO much pinch when the engine is cool, and it won't roll over when it's cold unless he heats the head up first. This is typically a sign that the engine isn't fully broken in yet, and it will go away once the engine is properly run in.
In my opinion with this design of engine, they should all be pre heated to close to operating temp to mitigate the wear with a cold start up, even after break-in
I should note that i have not used this engine for anything since this test - so can't tell you if would last any length of time (i'm guessing maybe just can squeeze a little life out of it)
yeah if this was a good pricey engine i'd probably do that. In this range the sleeve/piston are not much less $ than a whole new engine and i like having the extra parts around

I port3d one of these engine it was a screamer but the conecting rod broke
👍👍 love stuff like this. Great job

@@VBshredder bro I got into rc again recently ima try to fix up my nitro I have a arena senton 6s and a losi super Baja Rey 2.0 super simple machines
I was thinking of trying this on my old jp.12 nova

@@VBshredder thanks for the quick heads up
You could always just buy a new sleeve and piston set if your pinch doesn't work.

You can actually do it with a bicycle seat clamp
Need a big head thing
Does it work. ???
haven't used since! so maybe at best, better off just getting another cheap wngine
