Will a thunder tiger pro 61 muffler fit an OS 61fx.
I lost the tail section off my OS 61 and Tower wants 42 dollars plus shipping for the whole muffler.
The thunder tiger's muffler is only 18.

The whole muffler will interchange on the two engines

Thanks I've just saved a bunch of money

if you have what you need to fix your muffler thats cool, i have a tail pieces of an os 60 engine and its just sitting in my box, if you are interested let me know and i will take pics of what i got and if you may want it let me know you just pay for postal shipping you can have the muffler parts that i have

I could sure use them

Sorry for taking so long to get back with you, been a little hectic from the holidays and family and stuff, so here is the pics that i have, the muffler is from an OS E-4010 so if that is the front part that you have this part of the muffler is what i have that fits but if it is another muffler number that i dont know unless i get a digital caliper and mesure the dimensions to see if it fits what you have. The two pictures here the tail peices are the ones that ill give you but im including the picture to show that is or will fit if you have this model of muffler.

oh and by the way i do not have the center bolt because a bolt from another muffler broke and the center bolt worked on that motor worked, it threaded right in so i only have the tail end of the muffler as you see in the picture available

Thats great I have the bolt

A threaded 4-40 rod works as a replacement.
