| when you say you punch the throttle and it bogs, how much throttle are you giving it?
the pilot controls idle to 1/4, the needle controls 1/4 to 3/4, and the main controls 3/4 to wfo. sounds like its a little lean in whichever part of the throttle range you're in. |

| if i give it hard throttle it will bog right on the bottom end.... but if i just ease into it then it runs fine.... i tried to do some standing starts and was bogging bad.. rev it up to mid rpm.. then dump clutch and push throttle hard to wide open... BOOOOOGGGGG.... then comes alive..... |

| soooooo my thought is lower the clip 1 position (Raise the needle) and go up 2 main sizes.. i have a 150 in it so i'll go to a 155? |

| try that and see if it gets the bog out of the mid range. then do a plug chop. |
