Heres a pic of my 25cc toro from ebay before isold it.Or before i converted it,ill have to post the pics and see what comes out.I bought these off of ebay and when i called the 1-800 number from the plastic shrouds to see how availible parts are for these the person actually said they where in the US,parts are easy,and there from toro and maybe a few other machines.The MB290 mac might be one.I still have the 1-800 number in my RC stuff[aeronautic files].
Well,i checkedmy files for the number and now cant find it.I may have sent it with the last motor i sold.I will agree with billzair though as this motors and ones from ebay where frm a blower as the throttle only ad 3 positions,and was a large black plastic piece with indentations for closed,idle,and wide open.
So heres the pics for Captn,and billzair is more than likely right also.
I also bought mine for $98.00 for a box of 4.Bought 2 boxes before he sold out.And i dont have any left.
