Sveiki, gal ką patarsit, užknisa negyvai "missfire" ant dujų, važiuojant benzinu viskas gerai. Dujininkai sako kad žiurėti komutatorius ar babinas, nes tipo jei kazkas blogai tai su dujom tai trigubai pasijaus. Dar pastebejau kad tas missfire ypac stipreja kuo labiau atšala oras.Stipriau pavarinejus ir kuo daugiau išyla variklis, to tų missfire buna mažiau.Ryte tik persijungus ant duju išvis neimanoma gaza stipriau paspaust, mašina tamposi.Žvakės naujos, keičiau ir komutatorius ir babinas (iš šroto ėmiau), niekas nepasikeitė.
Nuoroda i parametus, kai skanavau variklio grupes :

Taip pat nuoroda i srauto matuokles matavimus, max 227 g/s ar gera?
