Oh Shannon, there is something you can help me with. Some time back you sent to me the long bolt modification instructions. I recently had to replace my computer hard drive and I lost all of my saved e-mails. Would you be so kind as to re-mail that info to me?

Oh OK, well this line kinda threw me off.... "When I recently refurbished my plane I downsized the fuel lines in order to reduce the required vaccum pressure on the carb diaphram. What resulted was bubbles in the lines."

In any case if you end up with some 185s at some point you can indeed have bubble free lines.

Hi all,
At least now, we have another option to get rid of bubbles in the fuel line (it's actually vapor lock). Avgas is good in the tank for up to 2 years, another plus! Daffy

The whole lead thing is a bit of a minus.

If only the engine manufacturers would decide on a new standard of aviation lead free gas we could use that. Year after year I hear that 100LL will be unavailable shortly.

I'm not well versed on AVGas but this is all I need to know really. http://100ll.com/. Other things like increased plug fouling and ring sticking may need to be researched.

The Lazair is so efficient (185s) that I use small refill gas jugs (2.5 gallon see through plastic). Using these ensures little waste and always fresh mix. Unless you are just flying your butt completely off 10 gallons of 89-92 Mogas goes a long long way.

Life is good, no bubbles, sweet running engines and lots of flying.

Yeah Shannon, I have a propensity to confuse (my wife will attest to that). I should have finished my thought by adding that I changed back to the larger lines and the bubbles went away. Sorry............
Oh, thanks again for the bolt mod instructions.
