Do you have a damaged, broken or cracked engine crankcase?  Often they can be repaired. The photos show the damaged crankcase before and after repair.  The starter intermediate drive gear boss was broken.  This rendered the electric start option useless.  We welded in a gusset and machined the boss bore to OEM size. This repair was a 100% success. Tell us about your specific problem.  We would be happy to give you a quote.
