Looking for Information for an Okrasa 36hp Engine Build

[olivetree]

I am building a 36 hp Okrasa engine with the WW carb and head kit and 80mm P&Cs and I am considering also going with a 69.5mm stroker crank. I am trying to come to grips with the potential issues that the stroker crank may result in. My major concerns are reduced engine life and higher engine temperatures. I am not sure what compression I will be running but it will see ambient temps of 90 degrees in the summer.

I would appreciate hearing from people who have experience running 36hp okrasa engines with 69.5mm and stock cranks. I would like to hear about your experiences with engine longevity and engine temperatures.

I would also like opinions on whether anyone has had issues running stock 36 hp rods in an okrasa engine.

I have searched the Samba forums for this information but came up empty so I would appreciate any info.

Are you adamant about using WW carbs/linkage? Their heads are great, but need a little port work.

I ask because with the 80mm p/c and 69.5 crank, I'd recommend that you buy the Speedwell Okrasa to IDF manifolds and go with 36 or 40 IDFs.

Much more bang for your buck and higher quality carbs as well. Here's a picture of mine in the process of installing the manifolds/carbs. I'm waiting on a few parts to finish.
