first off, nice blasterI:I i just wanted to comment on the high idle... my blaster does the same thing when i have the choke on.. it will start normal and then kinda start to increase in rpms, then i normally adjust the choke in a little until it comes back down... i do this for my piece of mind, cuz i hate hearing it rev like that cold... anyways i looked into the issue with the high revving with the choke on and for 2-strokes it seems to be normal, and i know my engine is leak free (just checked it 3 days ago) and has good compression... it still makes me wonder why it does that, you would think the high idle would be bad for the cold engine.... but like i said, my blaster is running great so i wouldnt worry.... i kinda think it has something to do with the fuel level in the carb... i adjusted the float heights the other day because they were too low, and now it takes alot longer with the choke on for the rpms to go up, so maybe double check your float height, maybe i need to adjust mine a little more... stock carb float height is 20-21mm...
