Compression

[Wayne \"ELVIS\" Woodall]

Listers,       I gave my L20B a compression test (only at cranking RPM) and it measured 160 psi.. As i was told when i brought it last year that it needed to run on decent octane fuel, i thaught 160 psi was low.as in normal compression. Now the idiot that i am, i had the throttle closed. A retest with wide open throttle gave a compression of 240 PSI at cranking speed with a big cam.. Does this mean AVGAS only ? $$$$$$ or say 50/50 mix avgas & PULP.       -Wayne   --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
