Frank Bowman "hringja smiður" sendi mér þessar leiðbeiningar um það hvernig maður lagar "reed valve-inn"(einstefnuventilinn fyrir innan blöndunginn) fyrir þýðari gang og meira performance á kína vélunum, þetta á þó við alla bensínmótora með þessum búnaði og hafa margir DA kallar séð góðan mun hjá sér. Þetta snýst semsagt um að fá plöturnar til að þétta svo einstefnuventillinn virki í raun sem einstefnuventill:

All China engine reed Block Mod.

I found that on the rear intake's there is a Black plastic or Aluminum reed block between engine & carb. It has a flange on it for mounting to flat carb & engine surface and reed part is triangular shaped. The reed block surfaces are not flat and reeds in some cases don't lay perfectly flat against block. The gasket surfaces often times are not flat either and need to be sanded down to flatten. In some reed blocks there are 2 screws that go thru a steel plate that holds reed to surface. On other reed blocks the screws just go through holes in reeds. Remove screws and reeds from block, then file or hone metal plates if supplied flat as 1 side will have burrs from having been punched out and holed not drilled. Next tape down 320 grit sandpaper to edge of really flat surface, table top, edge of thick piece of glass, etc. Because of the lip on plastic block, let that part hang over edge and pull plastic or Aluminum block across paper to flatten. Repeat on other surface until the surface is flat. It won't take much so no need to get carried away. Next deburr the 4 screw holes as screws tend to pull plastic up in screw holes. Remount screws thru plate & reed or just reeds. Make sure reed is totally flat, if not remove screws again and turn reed over and reinstall screws. Screws will strip easily so if you have lock tite you can put a tiny bit on screws to secure & tighten gently. What this affects is idle, engine will be hard starting as if 1 or both reeds are open ever so slightly, fuel won't be drawn up to carb and stay there. If reeds are open it never will pull a vacuum to draw fuel and hold fuel at carb. Thanks Frank.
