Fitting the engine was a heavy task. Right now I'm running it without filter and with a shorty "oregon" spark plug. At the moment of the build I haven't access to a "slant head".
Is there any shorty spark plug that delivers the same performance as a NGK big plug?[/QUOTE]
Get a filter on in real quick you can score your piston too easily if dirt gets in there !
