I have a gas compressor. I really want to get a nice sized electrical one but I just can't afford one right now... and looking into the ones I can afford, only produce about 6-8 CFM...

I have a gas one that has always had enough CFM for me to prime my cars... but never enough to run a d/a sander. Maybe my d/a was just a hog, but it would only run for a moment.

While looking into compressors I realized that I might not absolutely need a compressor and my gas one might work ok if I get a part fixed on it again... maybe I just wasn't using it right... so here comes the question.

What max RPM can you usually run a gas compressor at... do you usually just let them idle, or do you increase there speed relative to the more air you need?

I ask because I always through you just started them and let them idle... it gave enough air for most things... but not enough to run a D/A which is a must...

Now the compressor is a dual stage... max 175 psi with about a 14 - 20 gallon tank and an 8hp kohler engine. I think that this compressor should put out enough air to run a d/a so I must be doing something wrong... i'm thinking that maybe i should have been giving it some throttle.

let me know if i'm wrong or right... and if you do actually increase the motor speed when you need more air... can the compressor usually handle this?

All gas compressors run at idle when unloaded, but when needed they 'kick up' to a pretty high speed. Yours must be missing the air tubing to that throttle-device that does that. Get it fixed, 8 HP in gas is like 15 cfm, plenty for you d/a. Kohlers are nice engines, a little loud maybe...
Hope this helps...
