Its not an original McCulloch. It's probably a Weed Eater 25? That's not to say it didn't say McCulloch on the outside case?
Did you put a bigger carb on? Can you open up the muffler?
In the picture is a McCulloch 32. I have a few of them
I recognise your engine... I used to have the 26cc that I bought already modified. I hated the exhaust retention...
The carb is stock, Although I have a spare, it's the same size. I'm reluctant to spend money on the engine, but if I come across a spare carb, I'll try it.
I'm thinking about doing a custom exhaust in ally, much bigger - and hopefully lighter.
Thanks
