Does anyone know if a 2-stroke would run without exhaust on it? I know it has alot to do with how well it runs, but don't know if during a rebuild, firing it up before completely together is possible......
Thanks for the info. I will be patient then and wait until I have the Blaster all buttoned up before I try to start it. I did try to start my other project, a CR 125, last night for the first time since I got it and did the top end. It had spark and gas, but wouldn't fire...thought maybe because exhaust not being on. Put it on and still no go. Went through all the electrical measuring ohms and put it back together. Ends up it was just cold blooded and need to hold the throttle wide open to get it to fire up.
it wasn't overflowing gas when I was having a hard time starting it. now, it'll start on first kick, but won't idle without holding throttle up a little. Wierd thing, the idle adj and fuel/air screw won't fix that. probably tear carb down again. I did measure the float last time and it was right. maybe a bad oring or something. And I think the jets could be lean. they are stock, but the cylinder has 1.5mm bore, a full pro circuit exhaust with carbon fiber reeds. I have some things to check out here....
