Lagi-lagi Soal Starter Sulit Saat Pagi Hari

Baru-baru ini perlu 5-6 kali starter baru eljot bisa menyala lagi saat pagi hari. Dugaan sementara ada di sistem penyelaan atau di sistem bahan bakar. Karena gejala ini muncul saat platina sdh mulai habis daya kontaknya tapi diganti baru tetap sama juga sulitnya. Mungkin karburator perlu disetel lagi.

Sebelum utak-atik sendiri di kala waktu luang (jangan pernah percaya dgn bengkel/montir mana pun sebelum Anda mengujinya sendiri!), baiknya kita lihat kitab suci LJ80 Service Manual mengenai Poor Starting.

Sepertinya perlu service karburator, bersihkan dan setel ulang. Kalo soal ini mau tak mau harus dibawa ke tukang service. Karena terakhir bersihkan karburator di tukang service tahun 2011 (4 tahun yang lalu!) seharga 100k.
