Default I'm trying to help but!!!!

We have a new club member that I met tonight. He has a super tigre 60 or 61 that he is having problems getting it to run OK. Seems like I seen some post about the spray bar having to be pointed in a certain direction. Does anyone know if that is a fact. Also, this engine was made in Italy and If I remember correctly they don't like a lot of nitro. Again is this a fact or myth? Thanks for the help

If memory serves, the spray bar opening needs to be pointed straight down the throat. Most come from the factory correct, but I've had a few that needed rotating. There was a thread years ago (at least 10) that talked extensively about this, what symptoms, how to correct, etc.

The spray bar is for the mid range adjustment. To lean the mid range rotate a little bit at a time.

Is this a newer ST or an older one? If it is an older ST they did not really like or need high nitro fuel.

Manual is here. The old manual was better.

Start with the spraybar pointed straight down the intake and tune from there. If you are able to get a good high end and a good idle but a fat midrange, move it very slightly in either direction and retune. It doesn't take much to have a noticeable effect. And yes, these are high compression engines made to be sold in Europe and Asia where nitro more expensive. It will run well on no nitro or 5%. Some run fine on 10%, while some will never tune right due to the high end having to run so rich to retard the ignition timing.

They run just fine on 15% nitro as well.

The spray bar is close to correct with the fuel nipple pointed at the rear mounting hole. The few ST's that I have had that actually ran good enoough to fly with had the fuel nipple at that angle or slightly up or CCW from that position.

Sure wish everyone would take the time to read that thread Bill posted but it would tend to remove a lot of the questions posted from day to day.
