nice video where do you find parts for this engine these days??

[@RccarsrUs]

I collected most of the parts a year ago..some were from countries in Europe and uk (eBay) some other random sites.

I have the same engine but missing the pull start …can’t find it anywhere, any recommendations??

[@malo_213]

Hi hopefully you can help do you know the measurements, of the GX-21 bearings?? Thx

[@RccarsrUs]

not sure on the bearing size..as this video was some time ago if google gx21 inside and outside bearing size u should be able to find out..

[@malo_213]

What glow plug are you using?? I got that same truck and engine GX-21 but can’t find a pull start for it! Any recommendations?? Thx

[@RccarsrUs]

I was using a n3 glow plug…but these are cheap and iv now started to notice the difference with a os plug but go with hot plug which is good start point depending on the fuel you use

[@malo_213]

@@RccarsrUs OS what number? I just literally fixed my Kyosho pull start watch your video, that pull start is discontinued! I’m going to use 20% fuel..

Is it really worth it instead of a new better engine and why not the original airfilter???????????????

[@RccarsrUs]

At the time the crankcase was cheaper than a new engine…also I prefer older engines for the same price back In the day as a let’s say a kyosho ke series I found them easy to start and a lot more tuneable as for the filter I normally use these filters for setting up as it’s easy to pull off to check the carb idle gap and sometimes there drying from being washed so I use a different one
