idle help on 200s

[daniel_250r]

my 200s has always started first pull and run really well with lots of power but it can't idle worth anything. i have played with the idle screw and when i get it to idle i give it gas and it takes a long time to get back down to idle, or and when it gets back to idle and runs for a minute or so its starts to slowly die if not given a bit of gas. this week i started it up after sitting for 6 days and it was idleing very fast but still started first pull. any ideas? thanks in advance

If it starts idling really fast when you start it up you could have an air leak at the carb. My 185s sometimes acted like you are describing.

Whenever it takes a long time to come down from idle, its the airscrew or leak. Clean carb and blow out idle jet and adjust back the way it was.Beets

ok i guess i will be checking for leaks next time, anything else i should be looking for?

[daniel_250r]

and the air screw what will adjusting this do?

[beets442]

It adjusts how much air/ fuel ratio that is being taken in the carb. I get my idle first and then turn airscrew in and adjust out to the highest rpm. Fine tune idle again. Beets

stock setting o nthe air screw (bottom center) should be 1+1/2 turns out.

[daniel_250r]

ok thanks oscar i guess thats a good start to know if something is buggered with the jetting or an airleak

[oscarmayer]

the needle should be in the center clip also. this is factory setting,s from there you can adjust up or down.
