RE: SuperTigre mid-range problems?
i have read thru this form was hoping to find the problem i have with a st 2300. it is side mounted in a 1/4 yak 54 using a slim line smoke muffler. the engine startes very easy and has great low idle the problem i can't get a rich setting at high end, no matter where the neetle valve is it runs the same on the lean side i have checked every thing
the tank is right the feed and fill lines are ok i get pressure out of the muffler. the engine runs the same from 3 turnes of the needle valve to 1 turn from falling out if you pinch the fuel line it just quites i called st service they couldn't come up with anything except send the engine in the compression seems ok for a new engine i don't want to keep running it like this but i'am at wits end have a lot of smaller st have never had this problem i still run a 1965 tiger 60 it was the first engine i ever purchaced don't know how many hrs. are on it must be a few
thanks
