Engine rattle?

[Quingquad]

Hey guys, my blaster got a new top end. I think I might hear some rattle from the top when I run it. Not sure if I'm just being too finicky... Can someone look at this video I posted on youtube and tell me what they think?

Have you done an airleak test on it? Seems to have a stumble...to me

Yeah, do a leakdown test, but the idle sounds good to me...its a bit rich, but that's good... I don't hear any piston slap or rod rattle. Just noisy reeds like every Blaster has.

Thank you all. I'll test for leakdowns...

If ya have a leak first check around the reed cage -classic place- then the cylinder base and head. Hopefully it will hold 7psi. I let mine hold for 15 minutes but ya really only need a minute, anything over 1psi is a leak

i dont know sh*t really since i have only heard my blaster in real life but it sounds pretty good to me.

mine sounded like that a while back leak in reed cage but doesnt sound to bad

"Not too bad" is the way things blow up. If you think that you can "get by" with a problem, your probably wrong.

Sounds normal to me. If it sounds like this however you got trouble.

I did a leakdown three times now since i rebuilt cause im always worried. So far so good. A little rich dont hurt a thing.
