Conversion Cost
I found a 5+ cubic inch Husqvarna chainsaw short block (no carb or mag coil) in the Goodwill store in Flagstaff for $4.95..Excellent condition...A hub made on my Enco lathe will cost me about $2.00 for some 2" diameter 2024 aluminum bar stock..The mount will be made from 4" diameter 6061 round bar stock, about $5.00 worth, bored on the same Enco lathe...I make ignition, so that will cost me **** ( I could tell ya but I'd have to kill ya) dollars, with a coil bought from C&H, about $20.00....A new Walbro SDC 80 carb is about $41.00..The carb insulator block is made from G10 epoxyboard, about $22.00 a square foot, so about $.75 worth for that....
Lets see, $4.95 +$2.00 + $5.00 +$20.00 + $41.00 + $.75 is $73.75 and a few hours labor.Weight ? 5 lbs more or less,,,.....Warranty ? Lifetime on the ignition, chainsaws never wear out, not needed on the carb...Cheap enough ? It CAN be done....
$500 + dollars for a 50 cc ? NEVER.......
