Microlighters

Hi everyone,

Mostly, when I start my Mizer after being inactive for a week, it would only start on what seems to be one cylinder. It would shake violently & regardless of what I do, it would not get out of this situation.

The only cure is to shut down, & start again whilst holding the starter in until it runs smoothly, which happens quickly.

I've also noticed that on some first starts that it smokes heavily for quite a while although the internal oil injection system is diconnected & I premix my fuel/oil correctly.

The above happens, even if I prime the carbs with fuel (through the air filters) beforehand. On Saturday my battery was not strong enough to remedy this situation & I had to wait until I could jumpstart on Sunday before flying.

After the first start, it performs flawlessly, no misfire, smoking or more heavy starting at all.

Any ideas - I was contacted by another Mizer owner who stated exactly the same symptoms on his, so my problem is not unique.

Regards,

Henni

Hi again,

Someone suggested to me that it might be the fuel left in the engine carbs from the previous week's flight - most of the components in the fuel would evaporate leaving only the oil behind which then causes the smoking on the first fresh weekend start.

Only problem then is, why don't more experience exactly the same?

Henni,

See John Young's starting technique elsewhere on this site. The most common reason I've picked up why people battle to start their engines is low float bowl levels due to a period of not flying or trying to start the engine with the throttle open. You shouldn't get so much evaporation that the "residue" (or slightly two stroke enriched fuel) becomes a problem after only a week.

If you've got a primer, run it until you can hear your system is full (the pump's note changes once the lines are pressurised). Otherwise manually turn the engine with the mags off to get the "juices" flowing as per John's technique. You can fill the bowls manually but I think this is not a good idea as most people use their fuel tank drain to do this and it is unfiltered junk just looking to cause an engine out.

Hi John,

My sincere apologies - I forgot to thank you for the link. Will try out this weekend.
