Well while waiting for the OKO 26 Flatslide to arrive in the post i decided to look into the lacking compression a lil more.
After checking the valve clearances I pulled the head off for a look...
I found that the exhaust valve had a few large carbon deposits on the sealing edge which was stopping id from closing completely.
Stripped down head, cleaned valve and had piston and bore checked by a work shop as a 2nd opinion on if the bore was glazed at all.
Lapped valves and put it all back together.
Now the OKO has arrived and all bolted up.
I used some silicon vacuum line and zip ties to seal the throttle cable on the elbow.
The OKO was bought through KUSTOM minis who gets his stock from DHZ so im told its jetted 100 main 36 pilot with JJH needle.Needle in middle posi.
After a short amount of tuning the best i can get SO far is E clip middle pos, mixture screw 3 turns out and idle screw all the way in with choke on will start and run without any use of throttle.
At that point the revs seem to fluctuate a lil.
Push the choke in(off) and the engine dies.
Double checked cam timing just cos its only 1 minute job, all sweet.
Im going to have a decent go of tuning it over the weekend but if anyone has any pointers that may make it come together quicker fire away.
