I have been burning 10% ethanol/aka gasohol in my vehicles since the 80s and have never had a problem.

I put a 20% ethanol gas in my VW once and the thing made the most horrible sounds -- I thought it was going to die. I siphoned out the "gas," filled it with premium, and the sound was gone in about 30 miles. Never again.

That is why you should only burn 10% ethanol unless your vehicle is tuned to used the 20%.

ROFL!
Been there...Here's what you have to do on your VW.
1967 and older, you have to change heads. 1968 and newer, your heads are ok to use. You need the newer low compression heads. Set your deck height at least .070. Generally, that means one .020 cylinder spacer.

You need a high performance ignition. I use Omni-Pak. Stock ignition will not fire flooded plugs and that's what gives you the rough starts.

You'll need a larger main jet. Buy a selection of jets, they're cheap, and experiment for best performance.

If you like working on your own car, you will love the benefits of running alcohol in your VW.
If you want to build a hot VW, stay with the stock camshaft and use ratio rockers instead of a hot cam. VW does not like the steep ramp of the high performance cams, especially when running alcohol. Ratio rockers give all the increase of the hot cam without the disadvantages.
