Many thanks ordered

Please could any body send the link so as I can get the plans for the Mill 1.3 cc engine, I have tired many many places with no luck

Wow thanks for that will check it out. Being a very long time aero modeller I was looking at the transfer ports on a OS61 engine and there are three of them. The middle one is opersite the exhaust outlet, and opens well before the other two !! I guess this is to scavenge the exhaust out quicker???

Looks good but it running slow. Is there a reason for that, running in??

Now sporting a silencer!!!! Must change the 3mm bolts for mushroom heads!!

made a new head today, thinks it looks better!!

Video on you tube search for glow engine 3.2cc

The way the fuel is going into engine isn’t your problem. You are losing crankcase compression through the front housing. Fit bronze bush to front of housing and lap it to crankshaft don’t worry if it’s a bit tight it will bed in. Do you have electric starter? To turn engine over fast this will...

You could fit bronze front bearing, lap crank shaft to it

Meant to add you can use the same carberretta for two or four stroke
