Djet and E10 gas Options

[914rat]

There have been some comments lately about the effects of ethanol on our cars and in particular carbbed type 4 engines.Zach is switching from carbs to modern fuel injection due to the effects of the E10 on his driveability and I had a problem spring before last where my valves gummed up with a sticky residue and dropped a seat.

My question is do the guys that are running a 9550 cam and Djet notice any effects from the E10 fuel?What is the driveability as opposed to a carbbed engine?

I seriously doubt "my valves gummed up with a sticky residue and dropped a seat" is a rational statement WRT your engine dropping a seat. Heat makes seats drop. Timing, compression, too low octane, cracks, lean mixture, and a number of more obscure reasons contribute to heat. Oh, and headwork done by someone unfamiliar with T4 heads.

Let me explain.I let my car sit over the winter without without fuel stablizer.A valve stuck due to the decompisition of the fuel and broke a rocker arm and damaged the seat.The machine shop told me they have seen many cases on flat tapet carborated engines since E10 became the standard fuel.They had me feel behind the valve and it was sticky like maple syrup.They said the E10 breaking down was the reason for the sticky substance and the stuck valve that resulted in a broken rocker and damaged seat.Sorry I wasn't explicit in my earlier post.I have also had to clean my idle jets after only sitting for a few weeks something that was not an issue prior to me running E10 .I have drained my fuel system twice since the incident and still have to clean my jets if the car sits for a couple of weeks.My factory temp guage has never indicated a overheating issue.
