hello... my TZ3 has just been through its 2nd race last weekend and i was satisfied with the performance running againts novas,TZ5,Sirio's S....

anyway after the race i decided its time to dissamble it for inspection on the parts..

1. the top of the piston has black spots, compression still very strong...
2. the internal bearing brown colour, no excessive play and no need to replace i think
3. the cshaft internal and sides were very brown/rusted i think
4. the conrod has quite a freeplay againts the cshaft pin, so new conrod coming...

btw i have replace the conrod...but there is still freeplay againts the cshaft pin ( so should there be no play or a little or what...) or the c/shaft pin has worn out also

BTW my engine has gone through 3- 4 litrs of fuel (25% nitro, P6 glow plug, and 0.4mm head clearance)

like to hear some comments on this conditions...thank u..
