Tested a TT GP-10 has 160 deg timing but no bearings
I bought it new off ebay for 14 dollars cheap bid / was
for parts to rob the RC carb and thrust plate originally.
The carb on it now came from another .10 barrel needs
bored out to match the intake typical over sized for a 15.

Results after 1 rich run of 3oz. 20% nitro / 20% oil
ABC engine. Has a bronze bushing on the rod so tried
the modified MAS 5.22 x 6 / 18,603 / 106 mph
Well within a safe rpm range will do better with a 5.25x6.25
