Thanks guys for all your help.
I have had another afternoon playing with the Savage. Got it sort of sorted.....put it back to stock settings - HSN 5.5 + 1/2 turn, LSN 5.25 - and loosened the plug to start. It was still hard but it did fire up. Had to leave the glow starter on longer though. Running ok...... great! .....till pull cord snapped.......1 hour later.......fixed......spare cord on order!!!
I got it running through 6 (or 7 ish) tanks now on 20% and that's my half a gallon used. Going to buy 25% next. It didn't take long to get through the tanks as the mixture was really rich.
Do you think it will be ok to start leaning off the HSN now?
On the other hand, later, I got the Trophy Truggy 4.6 out for a blast ........ bloody love that car ....it's a demon!! That is running around the 270 degree temps though but got some decent smoke comin outta exhaust. May richen it up a tad to bring temps down a touch. That should be ok on 25% shouldn't it?
Cheers,,
