This thread is to take a look at the difference in the air injection on 505 and ( 2083 2077 ) ? compared to the 415 475 non air injected. Something I noticed on my 415 and 505 is they both use same air filter, carb, boot intake, even though the 505 is air injection.
mweba does your new 505 have different air filter and intake set up? David Young what about your 2083? Modifiedmark 475 non-injected what does it use?
Also the Jred and PP handles swap out. I see no difference in the two.
The only area I see that would need blocked is the carb cover hole to run the tanks of 505 2083 on non air injected 415 475. As you can see there is something on the 415 yellow cover where air injection could be and is blocked.
