hey guys.
i got an old homie XL-1 chainsaw that i started to strip down for a conversion.
it's gonna be run in a pusher config with the prop hub where the clutch usually goes so i can use puller props in pusher config. (some of you know that i run airboats)

but this thing has MONSTER compression and when i hold the decompressor valve in with my finger i can't pull it over (pull rope) at all due to the compression!!!
if i let the compression valve go it spits it out and will turn over with a little compression still there.
in the original setup there was a spring that held the compression valve closed but from what i can see, if it got say a hoge explosion or backfire it would blow out the valve and the spring would replace it.
understand?
it is also a reed valve engine

i need to get some pics for ya'.

but i want to know if this kind of compression is to much.
a review said that they like the high octane petrol mixed at 32:1.
