guide for 177 & 210 pnp tuning. all u need2 know about: carb cylinder piston ignition clutch & si fuel supply fuel tap fuel hose. simply follow the guide and there is nothing to worry about :) BIIIG enbarassing MISTAKE at 2:37, so SORRY guys! idle mixture screw of course: IN=LEANER and OUT=RICHER! ...
will add another short vid to correct it!

carb settings pnp tuning with 5&8mm bores in the airfilter:
177: 160/BE3/122, 160/55(2,9)=screw 3 turns out
210: 160/BE3/125, 160/55 (2,9)=screw 3 turns out

these are the correct settings for si carb based on many many engines. theay are all the same! IF this doesnt work with another engine, there is a problem and the engine not healthy.
ie: IF the idle Jet needs to be leaner = bigger than 2,9 the engine is sick, it could have an oilsucker for instance and/or a crank that doesnt fit the rotaryvalve pad (bigger than 0,05mm tolerance) NOT A SINGLE healthy rv si engine needs an idle Jet leaner than 2,9 as it is for the original 200ccm setup and we do what? Tuning! so it HAS2BE richer of course!
