so I have a 1998 blaster that would take forever to start and I had to use starting fluid every time I started it up, but one time it backfired and smoke came out from behind the flywheel, so I knew the crank seals were bad and I replaced them now runs better but it won’t idle. I have cleaned the carburetor, but that didn’t help. The reeds are fine, and I use 32 1 mix. Any help would be great!
