Bought a blaster 2 weeks ago 4 75 bucks! Complete!! Guy said it wouldn't fire so I bought all the electrical boxes on ebay 4 $35 shipped! Now it got fie but only when I give it gas. If you take your thumb off it will quit firing. So I took the thumb control apart and just layed the little switch out of the way and know it fires all the time but still wont crank. I also looked in the carb and there was a reed in it. Got it out and made a homemade one out of a bank card and still nothing! I've tried to check compression but it won't read anything! It will go up to about 15 every now and then but will not hold or build up! Its also blowing air and gas out of the carb. Not much but a little. It feels and kicks like it has got compression but dont know! Would love to hear it run but dont know what else 2 do! Any advice would be great!!
