Hello,

I'd like to install a muffler on my Cox Lazy Bee. I purchased two exhausts. One is intended for for the Cox/Kyosho Nissan GTP. I thought perhaps I could make a little muffler can and attach it onto the barbed fitting at some point in the future. The other muffler is just the standard ring type with a tiny little hole on one side. Eventually I'd love to find one of those Tatone type mufflers those look pretty cool. But in the mean time I'm not quite sure how to install these. I think I may have to take the cylinder off but I'm not quite sure how to do that. Any advice?\


Thank you,
Jess

Yeah, you'll have to remove the cylinder:

UNLESS, you utilize one of Roddie's innertube mufflers!! I can not find the post by Roddie and his muffer....Roddie where is it? ?

Well, that was confusing. So why is it that the top is to be with the flange up if using a starter spring, and down if not? I am not understanding why.

I do believe it is to allow clearance if the Starter Spring to wrap around the bottom of the cylinder? ??
Re-read the first paragraph, Flange down with spring, flange up without spring.

Re-read the first paragraph, Flange down with spring, flange up without spring.  

Be carefull, the instructions are not correct. Allways mount the muffler flange down. If you mount it the other way i.e. flange up, you won't be able to screw the cylinder down all the way. I've tried it. It doesn't work
