Hi hope someone can help - (tried a quick forum search but didn't have any luck solving this myself)

just started tuning my rush today after it's run in last week, as far as i'm aware the carb adjustment is fine, i.e. carb goes to full open at full throttle etc. The low needle has been leaned approx 2/8th clockwise and the high needle has been leaned off. Problem is the engine seems to bog down if you go to full throttle from idle and if it cuts out it's bloomin' difficult to restart. Any ideas? One thing i noticed after it cut out was no fuel at carb, if i opened up the throttle and took the glow plug out it took over 10 pumps of the primer to get fuel into the carb and cylinder, close carb, stick plug back in and it would start fairly easily- it was a pretty warm day today - could it just have been overheating and the fuel just vapourising?I did mark the low needles original position so resetting everything is not a problem. i still get smoke at full chat but think i've had my friends running quicker.

My mates savage 25 was playing up today too, hence why i thought the ambient temp was an issue.

Hope someone can shed some light on tuning this wee engine.

Oh, fitted purple rear springs - big difference to the handling, and the fibre brake disc - seems to do the job
