tower hobbies .46 carb
 

I have a .46 Tower that has been great for 3 years and now seems to be running rich at low speeds. I have adjusted the low end until the spray bar gap is nearly zero space and the engine still loads up at low speed. High speed is flawless and the engine reliable but the low end is a problem. Any suggestions for correcting things?

hmmmmmmm..

if it were a leak, it would run lean at idle. So that is not it.

A rule of thumb - you have an engine that runs well, and then suddenly is acting up. Solution: Change the glow plug.

If all else fails....get a new carb. Parts do wear out eventually. ;)

FBD. :D

I have a new one with the same problem! I ordered a new idle needle & carb body to fix it. Cheaper than sending it off for repair. (It's been sitting in my closet for over 2 years.)

Thanks for the input and am looking at the Tower catalogue. Always hate that as it makes the price of the carb real high when I order all the I wants too.
