I have a doodle bug with a Briggs snow blower motor...it's very punchy and easily kicks on stock doodle bugs and motovox ... until someone brought a predator....now I can barely keep up....I've already taken the governor off and I'm about to order some new valve springs (19lbs I think) and one of those cheep chiwanese carburetors of Amazon or eBay and more upgrades in the future..model and type are 09412 0202 any info would be greatly appreciated.
