Is it easy to remove the carb from the 650 H!? What do I have to remove? How long did it take you?
Thanks.

 

Noticed you havn't gotten a reply yet, so I'll try to help. I don't have a 650, but I checked the diagrams and it seems the two are similar enough. If it is your first time to pull a carb, then take your time. Remember what hoses go where, be careful because the screws that are used are easy to booger the slots, don't adjust the pilot screw without researching the subject, clip a wire from a wire brush or use compressed air to clear jets, try not to get carb cleaner on your diaphram as it can deform the rubber. After you do it a couple of times, you can probably pull it, clean it, and have it back in in 30-45 minutes. Also add an in-line fuel filter, and treat your gas with sea-foam. This should help prevent having to pull the carb too often.
