Stihl BG 55 65 85 blower

I need to know is the cylinder bore size different on these models or is it the carb size that make these models different.

I'd recommend the 86 to you, it's a far better performing machine.

Check their online site for spec'.

Good luck Phil

I am not asking which BG is the best blower. I fix these units and want to know if there is a difference in bore size on all 3 models or is the carb a different size that makes the better power. If the bore size is the same on all the BG units I want to install a carb from a BG 85 onto a BG 55 to make the unit a BG85.

I was told the carb and exhaust tip are the only differences to the engines, 85 has carb and larger tip, 65 has either carb or tip. I've seen one 65 and it had the smaller exhaust, so it must use the carb for more power.

The bore size is the same on all 3.
