Thank you all for the encouraging words. I haven't driven my Speedster in a few weeks because of being emerged in the Type 4 Puma project. I drove it to work this morning and was delighted by how nice the Suby Speedster drives and was wondering how I got pulled back into the torturous world of air cooled hell! I can't explain it, I thought at one time I was through with this but I got pulled back in. There is some inherent attraction of the air cooled engine. I have memories of a special type 4 engine I bought from a builder in New Jersey back in the late 90's and this engine was amazing and bullet proof. I ran this thing hard and the worst that ever happened from over revving trying to gain another 10th of a second auto crossing the car was having a rocker arm come loose from the push rod.
I am tempted to go straight to a Suby conversion and sell the Monster type 4 off once it is fixed, and there will be money involved in the fix. I should know how bad as early as tomorrow. My guy is covered up but I know he will be tempted to tear the engine down to find out what is broken. He said he was surprised something broke. The engine was built to take a lot of rpm's.
