Hello. I ride a 79 Vespa Ciao. I bought a 78 Ciao, assuming I would use it for a parts bike. Well, I didn't end up taking anything off of it, so now I am going to get it started. The gas tank is VERY rusty, and I read a week or 2 ago to use vinegar. So this is my plan. I'm going to totally fill the tank with vinegar and let that sit for 2-3 days. Then I am going to drain the tank and spray it out with a high pressure hose (car wash). Let that dry, run plenty of gas through it (to get out any remaining vinegar or water), and call it good (with an external fuel filter of course).
What does the army think about this? Sound like a good plan? Is there anything I should do different? I'm hoping for some feedback from somebody in case I'm about to make a huge mistake. Thanks in advance, this forum is the best!!
