Starter cup

Post by ted johnson » Thu Sep 17, 2020 11:52 am

West Bend 700. Has anyone installed a belt starter cup without drilling/tapping the flywheel to add a screw head to keep the cup from slipping? I'm used to Mac and Bonbright West Bend flywheels that both have screw heads engaging the pockets in the back face of the starter cup. If the nut is properly torqued to 27.5 Ft./Lbs., will it slip? Thanks. Ted

Ted, you can probably get by if you put an internal/external lock-washer between the flywheel and cup and also between the cup and nut. Also use red loc-tite.

Thanks, Dick. I'm using the GEM LH West Bend starter nut, so Charlie can start with a belt or a stick starter. I will get a box of the "Siamese star washers. Ted

As weak as those flywheels are I would not modify them. Dick posted my idea.

Rob, I'm taking the advice. I never fooled with a "round" West Bend flywheel before, but I remember Howard Wyatt, of Wyatt Enterprises in Cocoa, FL, where Charlie worked, had one red hot 580. He was forced to put the Mac flywheel and ignition on it because he blew up a couple of flywheels. That thing ran better than most modified Mc6's. He finally put a bushing in the big end of the rod, and he ruled the bushing class until the Mc2 showed up. He then took his Mc2 and basically turned it into an Mc7, and he was King of the Bushings again. Guys like him, Pop and me, who ran kart shops, had a distinct advantage! Of course, Wyatt was far bigger than we were, but we could still run with them. Ted
