My first build seems ready now after runin to start a series of 2-stroke do-able tweaks.
I am no expert on 2-stroke in a practical sense, mostly lawnmowers.
So if could ask the experts on 2 stroke HT engines, I have a 50cc, 2 weeks old and most interim bugs are ironed out.
The clutch works, the motor sits on frame stable and everything sits right and tight. Minimal vibration and starts OK.
Spark plug is NGK gapped at 25.
Needle is set at 2nd from top. Runs better at this setting than the settings it was packed with.
Exhaust gasket hole has been enlarged to equal outlet and the inlet gasket has been resized so there are no obvious air/gasket restrictions.
Symptoms;
1.On the straight is goes well, but loses power on a steep rise.
2.If I rev the engine out to full throttle, it seems as if this engine is
blow-up-proof.
It won't "scream". It will hold it's revs at full throttle with no obvious fear of blowing up. It feels like it wants to rev more, but something is holding it back.
Where do I start step by step to tweek this engine to reach peek revs ?
Thanks in advance.
