kt 17 vs mv 18 s
 

Hello guys I have a question about the kt 17 engine, is it the same as a mv18s if not what is the differance Thanks

KT-17 has points and coil ignition and is horizontal shaft. KT-17 series I has a low-pressure oil pump and spray-lubed rod bearings. The Series II is full pressure lube. The MV-18 is a vertical shaft engine with magneto ignition and full pressure lube.

Thanks Matt after posting the question I did a search and found that subject had been beat to death :beatdeadhorse:The reason I asked was to determine whether to swap out motors in 1811 since I cant find a good used m18 without breaking the bank

Just to add to what Matt said,
The m-18 is the last and best of that flat head series motor
It has increased and thicker webbing throughout the block.
The flywheel taper is increased in diameter.
It uses Mahle FORGED pistons of robust design.
There were also running improvements in its design, like a 30* valve angle.
Thus the “Magnum” term really meant better/improved.
If it weren’t for emission requirements and fuel improvements I’m sure it would still be in production.
