Air Filter
« on: January 18, 2012, 09:23:07 PM »
It just goes to show you have to check your air filter, My engine is a 6hp Lister running a ST5 alternator.

I have been experimenting with different fuels, so when I needed to start it from cold it needed some help, took of the air filter and heated the inlet as I turned the engine over.
Started got up to speed, I replaced the air filter to find it got sucked on like a vacuum cleaner,
looked at the volt meter, the alternator dropped 2volts, took the air filter off, volts went up 2 volts...

Just goes to show how much power and fuel loss a air filter can course even when looking OK.

K&M?

The original oil bath unit for my Witte is going for $100 so I went with a K&M including service kit for around $60 on Ebay.

My smart fortwo was the source of my 7.5 VA's muffler &  now it looks like the K&N filter will stand in.... my engine came without a fllter from  the factory I think it was spec'd that way as there is a coarse screen in the opening, looks to be 1/16 or 3/32 '' diameter holes when I get down & peer up into the inlet.
I'll keep an eye on the rpms/voltage when I test it.
