[vwbuge]

yes. found a forum or two but always like to check here first. No matter what the subject I find advice here a little easier to find.

How is it out of tune? Why is it not running right or what do you notice? I can try and help but need more info!

I have to buy a C battery for the ignitor to try tonight BUT a few months ago it would start fine. Low speed and take off were OK but it would not "wind up". When you would give it full throttle it would just trail off and motor would die.

What is a good base setting for the high and low mixture screws?

I fly RC planes, so I am not very familar with the car carbs. It would depend on the type of carb. Usually, twin needle or airbleed carb. I think the cars are twin needle. For the high end, I would close it all the way, then 2-1/5 to 3 turns out. If airbleed, there should be a hole that air gets suck into, and a screw goes into it from the side. Position the end of the screw in the middle of the hole.
I think the car crabs have twin needles or a needle vave on the low end. I usually turn them out 2-1/5 turns and go from there. A friends said on Super Tigres, you stick a 'T' pin (sewining needle should do) into the carb and close the throttle barrel on it. Blow through the fuel tubing. Open the neddle valve till air starts to flow. It should be close.
I'd also try another glow plug. They do go bad. I don't know how rough the car engine are on glow plugs.

If any of you guys are into the planes, there is an auction here in town this Saturday with about 20 of those RC Planes. If interested I will pm you the auction flier.

I am into planes and have switched to electric. OP sounds like it's running too rich at WOT. I have a nice vintage enya 4 stroke I need to get rid of if anyone's interested.
