Hi folks - I've had a two times recently, now that it's warmed up a lot, where it won't start without multiple attempts and opening the throttle like mad. It feels like it's not getting gas to keep it going.

Removing the pet carrier, I see air (big old air pockets) in the fuel line.

I'd never had a starting problem before, and this all happened as it has warmed up from the 50s to the 80s suddenly and about 3 days after seriously overfilling my gas tank. I disconnected the that hose that runs to the charcoal canister on the ET4 tonight, so I'll see if that helps.

Is this vapor lock? I did a search, but never came up with hits for air in fuel line. Any tips other than waiting?

I know I can try unscrewing the gas cap if it won't start, so that's an option...I'm mainly after advice and diagnostic help.

What's also weird is that both times the non-starting happened about 1 hour after riding home from work. If I start it up again shortly after stopping, it's fine. Sitting for 3-8 hours at work both days it seems fine, too...might just be coincidence, but thought I should mention it.

Thanks,

Eric

Hi Judy,

It's an ET4. It's started every time since then, and I even rode it after letting it sit about an hour. Looking at it this morning after running an errand, and just now...it seems like there is less air in the gas line having pulled the evap canister hose off the carb (I pulled the hose off at the T not where it attaches to the carb). I wonder if that's helping.

I bought the ET4 late last September, and I remember on hotter days it was always a bit touchier to start. However, that's the same for my minarelli based 49cc 2t I have, too.

Has anyone else pulled their pet carriers out and looked at their gas lines (especially if you're somewhere where it has started warming up after winter)?

Anyone else see some air in their gas line?

If it's not the air in the line causing problems, I may have gotten a bad tank of gas. This all started after overfilling the tank, and the gas is 91 octane ethanol free. Because of cost, and it being a smaller station...I"m guessing the gas could have less than stellar. I may just go with ethanol based 91 octane where I know there is higher turnover in future.
