RE: Outlaw with webra .36 problems
Newflyer,
These Webra engines are designed to run on low nitro, 10% being the limit, so that 15% may require a head shim...
This is an ABN engine and as such should be broken in as per Dar Zeelon's recommendations... Do a search here, he has written a very good thread about break in. Break in shall be performed at full throttle on a not that rich main needle setting.
It may sound obvious, but did you check that your fuel line is free from gummed oil deposits that would put to much restriction ?
