Now thats going in my favorites file for sure. Theres some pretty damn good info there and a reall good find. thanks ajonr.

As far as a magic carb. I dont know I have only seen the walbro. they all pretty much work on the same principle though. I dont know that specific numbers will do you any good as its gona be very hard to find that specific number. they are all pretty much the same within the venturi size ranges for each size. the only real differences are gona be little thing like throttle arm configuration and choke style or configuration or fuel inlet port direction some even have an integral fuel primer but again this is all secondary differences to the primary operating principals of this carb.

What i would do is look at the walbro site i had posted erlier for information on a specific carb you are looking at to identify the venturi size. this is gona be the only real operational difference in this carb.

Man im gona read that walbro tunning site a few times for sure lol. In browsing through it i now see why when i open it up full throttle and hold it it leans out and reduces rpms and no amount of richening the needle will help and now whatt to do about it.
