I once had a G3250 that couldn't be tuned for proper midrange..... even by the people at Perry. They offered to set it up in return for borrowing the engine to develope a Perry carb for it. The message that came back is that there was some sort of timming problem and it couldn't be tuned for anything other than wide open or idle.

This info is actually second hand as that is what I was told by Mike Hurley....he gave the engine to me and I couldn't make it work in the midrange....even with glow plug heat. Then I gave it to another fella and he gave it to someone who gave it away to sombody who was happy with running it at full throttle....or so I was told.

I also had a ST G51 that ran well once I found the right plug and filed off the burr on the glow plug seat.....and sealed the muffler with permatex and put a peice of fuel tubing on the needle valve.

I also had a G61 that ran like a top right out of the box...well with a little fine tuning.

My point is that Supertiger probably has good designs that occationally suffer from poor quality control. With that in mind, I'd rather not gamble with that brand any longer.

BTW, if you get a Supertiger, be sure to check for metal filings where the carb attaches. Both my 51 and 61 had a large shaving in there....looks like it came from when it was drilled for the hole where the brass carb retainer bolt goes. I got this heads up from sombody else who experienced the same thing.
