Hyper Engines Argh!!!!

[greenplane]

I am a seasoned RC guy , i buy and sell maintain etc
However I have recently had two problems with Hobao Hyper engines, both dont and wont start , all factory settings warming of engine etc but nowt, plugs are good and work out of engine fine and in fact in other engines great, fuel is new 20% , But both a hyper 21 and a hyper 32 will not start the larger went back as it was a shop bought engine as i work in a shop too. however the .21 is mine for one of my own customers and no way will it start.
So any ideas thoughts would be much appreciated
Thanks
Mike

Hi had a problem with one of the but pull start one would never fire so I tryed a small drip of fuel in the plug hole then fire it my engine started every time but don't put loads down there just a thought might be worth trying:thumbsup::thumbsup:

I too have had problems with Hobao engines in the past. Was given a .21 and later found myself the owner of 2 macstar 28, one of which was spanking new, but do you think I could ever get any of of them to work properly? More chance of an arm growing out of my arse. They all ended up in the scrap bin at work.

I have no answer for you though, sorry.
