ok. still having problems with the engine. I have tried the different needle settings but they made the bottom end way too lean.
Here is something interesting.
My TOP TSR12S3 is the latest modified version (like the ones in the magazine) but the crank opening (the one that the carb exits to) does not have RTV or anything in it. The opening actually goes another 3mm further back (toward the clutch). I thought these engines were suppose to have filled crank. Wouldn't this cause some fuel flow issues is that volume is too big.
Can someone else take a look at their engine to confirm this.
This may be one of the causes on my problems.
That's normal, it lightens the crank.
Lean it out! What king of fuel are you using? Any shims added? What plug?
