Get me the model type and code from the Briggs engines.  I can get into the the MTD system and find a model number or several that used that engine for a certain year that would narrow down your possible matches if the diagrams list the engine used..
		
		
	 
Where would I find the motor model and type?  There is a metal plate stuck to side of motor but all it has is oil info and emmission.  I found a couple bar codes on the mower deck.  One says Lot # TM1QC56  then SN# 5X65RU/162A0829
another bar code that I suspect is a IPC number: 43033571727.  I do not see motor model.  Is it under the cowling for the recoil start?
The metal tag on the motor says:
Emission Control Information
 MTD Consumer group
EXH Family ECZHS1591V1   ECS EM Disp: 159cc
EVP Family ECZHPNEQCPX  CPXP   ECS: CP
the rest is oil info, valve lash, spark plug gap.
Thank you.
