Brought my van to Rainer at ORRATECH on Thursday. He is a very nice and proficient guy! He checked the engine properly. The main reason for my engine trouble was a lack of fuel supply due to a rusty tank! The rust blocked the fuel pump-not good! Now I have a new one, the tank got flushed and modified. Carburetors got blown out. There are still a couple of other minor problems I will have to sort out soon. But for now I can ride the van! Yiiihaaa!
