Item description: Backpack blower Brand: VEVOR Item: B0DCF9FMB2 Date received: 2024-09-11 Headline - 50:1 oil/gas, check for kinks in the fuel line in gas tank if it won't start Product Claims 1 ct, 79cc backpack blower, right-handed The product arrived well packed. The blower tube sections and controller assembled easily. The manual noted that this is a 50:1 engine, which I did NOT see in the product description, but that is normal for modern 2-cycle engines. The manual is marginal and the controls are not marked with the purpose of their positions - but that is really only needed for the initial use. Still, recognizable controls would be nice, and that really is expected for a 5-star product - the start/stop button has the functions molded into the orange plastic button but there is no contrast, so which way to push the button for start is nearly impossible to see (down is start). The choke lever doesn't tell you whether up or down is choked (it is up) - a simple contrasting choke symbol with an arrow should be there - it is not. The primer pump is underneath the carburetor and in the unit delivered to me is obscured by the fuel suck and return lines; literally impossible to see from any normal position - I looked for it for 10 minutes before realizing where it was, and even then it is an awkward pump. Even after sorting all that out, and reading the cold-start directions multiple times, the first time start was still a problem... I followed the starting directions and broke a sweat while failing to get it started; I could see that the primer bulb was not pumping any gas out of the tank. I stopped, re-read the manual, tried again - no joy. I finally used a wire hook to pull the fuel tube/filter up out of the gas tank to inspect that system, saw nothing wrong, but in the process I must have unkinked a kink in the fuel line, because at my next attempt the primer bulb suddenly pumped well, started to suck gas, and the blower immediately started with no further
